SHOCK: The ‘Father of global warming’, James Hansen, dials back alarm

James Hansen: We Have a Little More Time After All (Whew!)

By Robert Bradley Jr.

“Contrary to the impression favored by governments, the corner has not been turned toward declining emissions and GHG amounts…. Negative CO2 emissions, i. e., extraction of CO2 from the air, is now required.”

– James Hansen, “Young People’s Burden.” October 4, 2016.

“The ponderous response of the climate system also means that we don’t need to instantaneously reduce GHG amounts.”

– James Hansen, “We Hold Truths to be Self-Evident December 2,  2016.

What a difference a few months make!

Just in time for holiday season, and for the Trump Administration, the father of the climate alarm, formerly a climate scientist with NASA/GISS, and now a full-time scientist/activist, has ameliorated his grand climate alarm. The 10-year ultimatum announced in 2006, made more dire in 2009 and since, is now moderated.

This October, we were told that the net emissions of of man-made greenhouse gases in the atmosphere must go negative. Now, “we don’t need to instantaneously reduce GHG amounts.”

A climate scientist might want to see Dr. Hansen’s math and model simulation to understand the revision in the last sixty days.

Maybe the climate can survive Donald Trump after all!

Here is the history:

Old View (July 2006):

“We have at most ten years—not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions” he wrote in his July 2006 review of Al Gore’s book/movie, An Inconvenient Truth. “We have reached a critical tipping point,” he assured readers, adding “it will soon be impossible to avoid climate change with far-ranging undesirable consequences.”

Revised View–Worse Than Thought (2009)

Several years later, with the publication of his 2009 manifesto Storms of My Grandchildren: The Truth about the Coming Climate Catastrophe and Our Last Chance to Save the Planet, he shared “some bad news” (p. 139) with readers:

The dangerous threshold of greenhouse gases is actually lower than what we told you a few years ago. Sorry about that mistake. It does not always work that way. Sometimes our estimates are off in the other direction, and the problem is not as bad as we thought. Not this time.

“The climate system is on the verge of tipping points,” Hansen stated (p. 171). “If the world does not make a dramatic shift in energy policies over the next few years, we may well pass the point of no return.”

Also in 2009, he told the press:

We cannot afford to put off [climate policy] change any longer. We have to get on a new path within this new administration. We have only four years left for Obama to set an example to the rest of the world. America must take the lead.

Revised View–Need to Go Emissions Negative (October 2016)

“Contrary to the impression favored by governments, the corner has not been turned toward declining emissions and GHG amounts.  The world is not effectively addressing the climate matter, nor does it have any plans to do so, regardless of how much government bureaucrats clap each other on the back.…. Negative CO2 emissions, i.e., extraction of CO2 from the air, is now required.”

New View (December 2016):

“Stopping human-made climate change is inherently difficult, because of the nature of the climate system: it is massive, so it responds only slowly to forcings; and, unfortunately, the feedbacks in the climate system are predominately amplifying on time scales of decades-centuries.

The upshot is that there is already much more climate change “in the pipeline” without any further increase of atmospheric greenhouse gases (GHGs). That does not mean the problem is unsolvable, but it does mean that we will need to decrease the amount of GHGs in the relatively near future.

The ponderous response of the climate system also means that we don’t need to instantaneously reduce GHG amounts. However, despite uncertainties about some climate processes, we know enough to say that the time scale on which we must begin to reduce atmospheric GHG amounts is measured in decades, not centuries. Given the fact that the fastest time scale to replace energy systems is decades, that means that we must get the political processes moving now. And that won’t happen until the public has understanding of what is actually needed and demands it.

Anthony Watts commentary:
I think Dr. Hansen has come to the conclusion that climate sensitivity is not as sensitive to carbon dioxide as it was once thought to be in his original a, b, and c scenarios from 1988. We’ve noted previously, that it is 150% wrong.

Figure 1: Temperature forecast Hansen’s group from the year 1988. The various scenarios are 1.5% CO 2 increase (blue), constant increase in CO 2 emissions (green) and stagnant CO 2 emissions (red). In reality, the increase in CO 2 emissions by as much as 2.5%, which would correspond to the scenario above the blue curve. The black curve is the ultimate real-measured temperature (rolling 5-year average). Hansen’s model overestimates the temperature by 1.9 ° C, which is a whopping 150% wrong. Figure supplemented by Hansen et al. (1988) .

This El Nino year is proof positive that climate sensitivity Isn’t anywhere near what he once thought it was. Right now Global temperature has fallen towards the plateau set from the 1998 Super El Nino, especially over land as seen below.
rss-land-data uah-land-data
Combine that with the fact that even as carbon dioxide has been increasing, temperatures have not been upwardly tracking with it, but instead we’ve seen El Niño driven spikes in temperature, which have nothing to do with CO2 sensitivity. The natural variation of the system still rules the climate.

    • Mmmm….Gravy, with thinly sliced Roast Beef, Roast Potatoes, Yorkshire Pudding and a glass of Red Wine. Just so happens this is what I am making tonight for dinner now in honor of Hansen. Cheers!

    • Basically, the guy’s a big opportunistic bullshitter. No surprises here. LOL. These people have the face of brass.

      • … formerly a climate scientist with NASA/GISS, and now a full-time scientist/activist,

        where does that nonsense come from? Hansen was formerly a full-time scientist/activist with NASA/GISS, and now a full-time activist,

    • When the global warming “gravy train” final reaches it’s last stop (none too soon for me) I wonder what train all these environmental folks are going to jump onto next? Hmmm….

      • Fear not. It will shortly be revealed that CO2 is still bad, but that it is causing AGC (Anthropogenic Global Cooling). The only fix will be to reduce CO2 emissions, or at least transfer money from developed nations to dictatorships and warlords. Someone merely put too many negative operators into the models by accident. That problem has been fixed. The threat still exists, and tornadoes, hurricanes, extremes of cold (and hot) will still occur, as will the incidence of earthquakes and meteor strikes.

      • Diesel !! Banning all cars from towns and cities. That will shut economies faster than carbon tax.

        They started if france 4 yrs ago

      • jump UNDER would be useful
        hansens trying to CYA in regard to sucking more govvy paid “advising” i reckon

    • Mr. Hansen also seems to be part of a kickstarter documentary project that will promote 4. generation nuclear. Interesting times indeed.

    • Exactly! To claim that it is already too late would stop the money flow.. Therefore, it is not too late, but is more critical and requires lots more money.

    • So the father of global warming tells us we’ve been lied to all along…
      ….the science is still not settled

      When they can tell me what happened when CO2 levels were in the thousands….

      • Lat, why should we listen to him? He couldn’t even measure temperature correctly and Gavin Schmidt is having to re-adjust all Hansen’s numbers year after year after year.

  1. About time Hansen went outside and realized just how wrong the models are. I’ve gotten really tired of hearing about how “sensitive” our climate is to GHGs when it is nothing of the kind!

    PMK

    • Dr. Hansen has wisely concluded that climate is much less sensitive to carbon dioxide after November 8th 2016.

    • Me too. I Simply refuse to let the climate liars get a pass while they destroy science as a noble endeavor with their deceit.

  2. This really is quite galling. One minute he is inciting a riot and the next he is chanting “…give peace a chance….”.

      • History, other than that “revealed” in socialist societies, always uncovers the real villains. Now, those reading history tend to interpret it in a manner that best reflects on themselves. Evidence Castro, anyone?

    • Paul H.: As much as I would like to believe in Cosmic Justice, I think we must just make do with what we can get. Whether tomorrow or in 10 years, the AGW mime will disappear, and so will all those True Believers, who will never, ever admit to having been believers….

      • Greg, I think most of them will just quietly fade away without ever admitting that they were wrong. But I think it will be sooner than ten years. Two or three cold winters in a row over North America and Europe, eliminate the funding in America, and that will be the end of it. The end that is except for all the residual damage like the lost jobs in the coal mines, the money wasted on wind mills and electric cars, the research grants for junk science that could have been spent on useful research, etc.

        Its the money that keeps it alive.

    • Agreed. After Hansen discredited everybody who did not agree with his and Gore’s predictions, and caused billions of dollars waste in research grants and renewable energy projects when neither could produce a measurable difference to CO2 generation, he is now backpedaling as if nothing bad has happened as a result of his stubbornness and stupidity. Not just taxpayers’ money wasted but also a generation of people brainwashed.

    • Does history remember the names of Ptolemaic mathematicians of the early 17th Century who created ever more elaborate equations to describe the Geocentric movements of the planets and stars?

      History remembers Kepler, Copernicus, Galileo, Brahe. To be sure not all of these got it exactly right until mathematicians could employ Newton’s Mathematica Principae. But still they threw off the wrong paradigm to embrace a new one, and history remembers them.

      History (long history of centuries) will not remember Hansen, Mann, Jones, Trenberth, Santer, etc, except in appendix chapters on the corruption and downfall of late 20th-early 21st Century atmospheric science.

      • But, it will remember Anthony Watts and WUWT, the “little engine that could.”

        November 17, 2006

        “So does anybody have any gee-whiz questions?”

  3. Well, isn’t that interesting -just had a recent debate with a warmist tool er, troll, on another site,
    who quoted Hanson chapter and verse….
    I’m bookmarking this for his inevitable return to this particular site…

    • @ tgm, please oh please can you show the conversation? I need a laugh after reading the disgusting about face from hansen. His ilk make me sick. I hope the new administration throws him in the ditch but I guess with hansen being retired he can now spout anything he wants without losing anything. Like your pension hansen? SCUM!, (sorry about the rant I am just sick of these sycophants)

  4. A desperate attempt by a discredited has-been to regain relevance.

    Once a researcher/scientist stops doing careful well-documented and reproducible work and starts carrying protest signs, that person should no longer expect to be listened to.

    • That’s the way I see it too. If he were to stick to his initial ten years to armageddon prediction, then at this point we all might as well say the heck with it, we’re cooked no matter what we do.

      I see the whole thing as entirely pathetic.

  5. we know enough to say that the time scale on which we must begin to reduce atmospheric GHG amounts is measured in decades, not centuries

    Oh. So all those papers claiming current climate disasters are complete bullsh*t then? After all, if the father of climate insanity himself is now admitting that the disasters he has been predicting are decades to centuries away, then he is at the same time discrediting any claim that current matters (real or imagined) can be blamed on CO2 emissions.

    • Excellent points! Additionally, I would say that if he really believes that there is a long follow on effect from increased CO2, he should be desperate to reduce emissions now, due to the long term effects. What kind of idiot logic is this guy operating from?

      • “No, he said the time was decades, not centuries.”

        But it will be centuries before CO2 emissions even start a downward trend.

        Live with it. :-)

      • Why would anyone want to reduce CO2 emissions? Don’t you want to eat?

        Present levels are a good start, but 800 ppm would be better and 1200 ppm, as in a real greenhouse, best of all. But we probably can’t even make it to 600 ppm in the next hundred years, if ever.

      • Nick Stokes December 3, 2016 at 4:02 pm

        Hi, hope you’re well.
        You are correct to a point. Decades mean a minimum of two and a maximum of 10. That not centuries part. It is a plural. So a single century falls within the time reference.
        Look, he wrote it, not me or you. You can see it as 20 years, someone else 50, and so on.
        As a result, it is a meaningless reference.
        Okay Hansen shared those observation this month. Who knows whar next. The truth is, Nick, he has left people like you with your butt’s hanging in the breeze.
        No matter what is said by the AGW side, Hansen’s remarks are going to be a club used to smack you across the head. Even if he recants, it won’t help. Instead of a responsible scientist to be taken seriously, he will take on the atributes of the straw man in Wizard of Oz.
        Unless Lew & Cooky quietly take him off to a padded cell …

        “The ponderous response of the climate system also means that we don’t need to instantaneously reduce GHG amounts. However, despite uncertainties about some climate processes, we know enough to say that the time scale on which we must begin to reduce atmospheric GHG amounts is measured in decades, not centuries.”

      • What he said in October, 2016

        “Negative CO2 emissions, i.e., extraction of CO2 from the air, is now required.”

      • “What he said in October, 2016”
        What he actually said, properly quoted, was:
        B. “Negative CO2 emissions,” i.e., extraction of CO2 from the air is now required, if climate is to be stabilized on the century time scale, as a result of past failure to reduce emissions.

        on the century time scale – similar to the decade scale to reduce actual amount.

        Mixed metaphor there. But there is nothing in what is quoted here that is any different to before. Just elementary stuff like distinguishing between emissions and amounts. Most people would be very happy if we can get the amount down within a century

      • Nick Stokes December 3, 2016 at 5:22 pm

        Thanks for responding.

        “Most people would be very happy if we can get the amount down within a century”
        Yes yesterday. Tomorrow? When what has been said hits the public that may change.

        All the logic chains are now suspect .
        Hansen admitted “our” estimates are off. Not his. He just grabbed you and dragged you down into the mud with him.
        Credibility is a fragile thing Hansen and by his association has included all of those involved.

        Nick there are people in Ontario Canada that are trying decide, do I, pay a electric bill, or buy food. A electric bill which has grown to such unmanagable preportions due to failed assumtions by climate scientists who believe in AGW, and the politicans who believed them. There is no excuse for this. Not in Ontario or anywhere else.

        Take a look at the Hansen statement. Do you really think people are going to care about getting the amount of of CO2 down after being deceived?
        It is going to get rnteresting.

        “The dangerous threshold of greenhouse gases is actually lower than what we told you a few years ago. Sorry about that mistake. It does not always work that way. Sometimes our estimates are off in the other direction, and the problem is not as bad as we thought. Not this time.”

        michael

        Oh and you do a good job of defending the side you are on.

      • Good point. He wants only to kill 30% of world population by zeroing CO2 emissions, and wants to leave the rest to the then impoverished future generations as a home work.

      • “The dangerous threshold of greenhouse gases is actually lower than what we told you a few years ago.”
        How on earth do you read that into it? That’s not what he is saying at all.

  6. Maybe the climate can survive Donald Trump after all!

    Trump has a site where one can cast one’s pearls in his direction: https://apply.ptt.gov/yourstory/ Here’s what I posted there two days ago:

    I’ve read that scientists and others are calling on you to walk back your skepticism 1) about climate change becoming a major problem, and 2) about “renewables” being the way to solve it.

    I suggest the you respond thusly: 1) “You alarmists make a good-sounding case, but so do climate-change skeptics. I’m therefore going to make my decision based on a series of televised debates between you and them.” (Those shows will draw big audiences.)

    2) Say, “I’m going to hire James Hansen (Gore’s main climate advisor) to head an agency devoted to promoting the installation of innovative nuclear power plants as my ‘no regrets’ carbon-mitigation strategy.” And say, “this path will cost half as much as renewables, and cut CO2 emissions twice as much.” This will split off the majority of the populace who are worried about global warming to your side.

    There are three other leading greens (one of them Stewart Brand of The Whole Earth Catalog) who signed Hansen’s open letter advocating nuclear power as the only realistic carbon-reduction option. Their standing by your side on stage when you make this announcement will give your position credibility. Probably many more will jump on the bandwagon after a month or two.

    You can float a trial balloon by inviting Hansen to a long meeting with you, which will set everybody a-tingle about what it means. It will prepare people for the shock.

    It is only about 20% of the worriers about global warming who are strongly anti-nuke, Most worriers will be glad to take the half-a-loaf deal you offer them. (Actually, 3/4 of a loaf.) I suspect many alarmists are secretly irritated by the anti-nukers in their midst, but don’t say so publicly, in order to maintain the unity of the movement.

    If you can pull this off—and it shouldn’t be THAT hard—you’ll be hailed for decades as the statesman who broke the logjam. It’ll be a major (maybe THE major) accomplishment of your administration.

    Just make warmist politicians an offer they can’t refuse. And if they DO refuse it, then the fault for your administration’s inaction on reducing emissions will be theirs not yours. After a year or two, at most, their obstructionism will crumble, and congressional Democrats will be willing to make a deal.

  7. After 25 years of Jim Hansen’s “death trains,” and ‘we have only 2 years to save the climate,’ and climate models that show an immediate air temperature rise with [CO2], we suddenly now have a “ponderous” climate system and decades to act.

    This is Jim Hansen stepping back because air temperature has done nothing for 20 years.

    Switching to a slowly responding climate is just his tactic to save his incompetent ideas from an empirical disproof.

    Expect no public examination of his self-contradiction; just an uncritical acceptance of his new gospel as though it were his old gospel.

    It’s nice how he managed to include a criticism of the West into his argument. “Democracies played an outsize role in creating the climate problem…” That’ll play well with his progressive demographic.

    Democracies played an outsize role in creating the climate problem” because they are places of freedom where incompetent demagogues such as Jim Hansen are free to mount a bully pulpit and incite political odium. The real “climate problem” is one of scientific incompetence buttressed by lies and supported by prejudice.

    • Obviously major sources CO2, volcanoes and bush fires, are “democracies”. Hansen would be better off trying to connect GHG/CO2 with El Nino and La Nina events. This would open up a completely new field of rent seeking. Give big government and the banks something to hope for Jim. They may throw you some “printed” crumbs. If you can’t come up with another globe blowing disaster based on need to live off others efforts, your time is over.

      • Clearly, he must see that “the gig is up” and that he has to find a new way of spinning himself into relevance and renew his funding. The GOOD NEWS for us is that this is very clear evidence that the cracks in the whole crumbling edifice of AGW theory, practice, politics and funding are so fast appearing that die-hards like the egregious Hansen are looking for new relevance. Sorry, buddy, go tote sandwich-boards to earn a crust … you are irredemably tainted with the label: ‘Snake-Oil Salesman’.

    • Pat
      One is left wondering how old a new CO2 molecule needs to be before it can absorb infrared radiation. Do they get better at it as they age? Do they get tired and run out of absorption capability in old age? This too needs to be studied more.

      • They don’t run out of absorption capability, but they do deplete the IR radiation that can be absorbed

      • That could be the answer, DMA. CO2 is now 25 years old, and no longer energetic enough to quickly warm the air. :-)

      • Alinsky’s rules:
        RULE 7: “A tactic that drags on too long becomes a drag.” Don’t become old news. (Even radical activists get bored. So to keep them excited and involved, organizers are constantly coming up with new tactics.)

  8. Add measurement error bars of +/-0.1 based on reading the foundation papers for satellite microwave brightness temperature. That’s a range of error of at least 0.2, on this y-scale it appears that current global temps are no different from 1980. Try plotting the same data with a y-scale of +/- 3 degrees and a 6 month running average to eliminate the high frequency noise. I don’t think the real world temperature twitches by 0.2 degrees every month.

    • Say that to a warmist at heights.

      BTW, it’s freaking cold here. You didn’t talk about error bars when it was anomalously warm here.

      Regards, 60°N

  9. I wondered what Hansen would do when his disaster scenario failed again. He seems to be oblivious to his failure–maybe he is still in shock over the US election.

  10. He has simultaneously moved the goal posts into the distant future while pretending that he is still credible. He is playing his believers for morons.

    • Not difficult.
      One should always remember that 50% of the earths population is below average intelligence.

    • Yes, perfectly expressed! Pretty slick way to hit the reset button. “Okay folks, the new countdown to disaster starts…………..now!”

      • It is interesting that with calamity-cults the norm is to give a date in the accessible future and when the prophecy fails, they make a new one.

        With the climate-calamity-cult it is different: they say that from now the calamity will occur in X or Y decades. They can never be proven wrong if they call a long game. The surprise is that for a ‘calamity’ to happen, they need a vaguely believable ‘trend’. The Pause is an absolute killer. We never get anywhere near the ‘decades’ of disaster and they re-call the game. This is a sure sign the prophets of doom haven’t a clue what they are talking about. Narry a whit.

        Has-been Hansen, I christen thee the Jim Jones of climate. Gather your nutters around you in some jungle hideout. I’ll send Koolaid. The real stuff. I want you to live there happily in the company of friends.

        I will continue my work of bringing warmth and cooking to these living in energy poverty. Deal?

      • As long as you promise it’s organic grapes with chinese herb extracts…They’ll be fine with that koolaide.

      • Crispin in Waterloo December 3, 2016 at 6:32 pm

        “I will continue my work of bringing warmth and cooking to these living in energy poverty.”

        For at least myself you are a mystery. Now more so. But it appears a good one.

      • To Mike the Morlock

        I rarely say what actually do for a living because ‘it is a bit complicated’. In a single week, the last one, I attended two sessions on introducing smoke reducing coal stoves for farmers in Hebei Province, attended a conference in Beijing on the latest testing protocol for cooking stoves and a NYSERDA conference in Albany NY on improving the performance of space heating wood stoves in NY State. While in Albany I offered to introduce to the Four Corners native Americans burning coal from Peabody a new stove technology that can burn coal without any smoke at all.

        The argument is this: hundreds of millions of people live in permanent energy poverty, defined as spending more than 10% or their income on energy. A great many of them burn coal, primarily. It is fantasy to suggest that this demographic be called upon to ‘reduce their energy consumption’ or their ‘CO2 emissions’. What cheek!

        There is a small cadre of people working on technically advanced solutions for people who are dependent on coal and who live in energy poverty. This field of endeavour is delivering some of the most advanced technologies and theoretical work ever done on the combustion of coal.

        The target populations live ‘outside the bubble’ of the enviro movements who not only condemn them to perpetual energy poverty but demand they ‘reduce their carbon footprint’ on the basis they use coal. In fact they use very little energy. My general goal is to make their lives healthier and to reduce drudgery. I am very fortunate in being able to to make contributions to this field.

  11. The American public (especially the smart phone generation) has the attention span of a gnat, so no matter what he said or did in the past, what he says and does currently is what he will be known for. That’s just the way it is and he knows it.

  12. Jimmy probably thought that he was going to be right in the long-term, so it was worth telling a few porkies in the short term. He forgot the medium term.

    But he still has a great hat.

  13. Jim is just following the Alarmist crowd by moving the goal post when the previous prediction in this case 2006 becomes self evidently wrong (again).

    Just like the Arctic Ocean was going to be ice free 6-years ago (made at the AGU Fall Meeting in 2007)!

    Ha ha

    • He had to do something. After all, in one month 2016 is over.

      Actually I feel Hansen sold his soul to the devil, and now all his good times are over, and he senses he has got to pay the devil his due. Not a very comfortable position to find oneself in, I surmise. He has less of a chance than a cornered rat, for even a cornered rat has a fighting chance. All Hansen can do, I fear, is flip flop like a fish on dry land.

      • I have been saying for years that he (and Gavin Schmidt) should stand trial for “falsifying public records”, for their “adjustments.” After all, every man deserves his day in court, and the right to prove his innocence.

        There might be some interesting “fallout” from such a trial. It might turn out Hansen was “following orders” from higher up. He might plea-bargain, and finger a politician or two or ten. Once things started to unravel things might get very interesting.

        I don’t think it is a crime to be an activist. Falsifying Public Records, on the other hand, is illegal. Likely a lawyer could find irregularities in how funding was handled, as well.

        I just wish Bill Gray was still alive to see all this, but perhaps he is smiling down on us from heaven.

      • IMO grant trough feeders like Mann could also be prosecuted. The chilling effect on real science has to be weighed against the trillions in treasure and millions of lives these criminals have cost.

        Jones is probably beyond the reach of US law, but his compatriot Schmidt isn’t, nor his fellow British Commonwealth citizen Trenberth, nor Hansen nor Mann and a host of other miscreants.

      • I first felt wrath towards Hansen when McIntyre’s careful examination of “adjustments” forced Hansen to retreat back in 2007.

        https://climateaudit.org/2007/08/08/a-new-leaderboard-at-the-us-open/

        I was so vehement that Hansen should be hung out to dry back then that my comment got snipped. (I learned a lot about good manners and patience from McIntyre). But I learned a lot about persistence as well, and about holding Hansen’s feet to the fire at this site, and Tony Heller has been a sort of pit bull in terms of tenacity, over at Realclimatescience.

        But it has been over a decade. Can you believe the knaves held on so long?

      • Some of the conspiracy ringleaders must be held accountable. Many younger academics and government workers had to go along to get along.

        McIntyre opposes, or used to, prosecution. But IMO their crimes stink to high heaven and need to be given a public airing. Let judges and juries decide the hoaxing hucksters’ fate.

        And claw back any and all grant money from “scientists” who don’t archive their publicly-funded data. The academic, green industrial swamp needs to be drained along with the Washington-Wall Street axis swamp. Sorry for the worse than mixed metaphor.

      • Caleb,
        In normal times a man is innocent until proven guilty. The burden of prof on the accuser.

        In these post-trut times of fake news from the MSM, men like Roger pielke Jr are ajudged guilty until proven innocent. Thus your observation, “everyman deserves his day in court and the right to prove his innonence.”

        Individual rights are meaningless before an all powerful state.

        We live in Orwellian times after 8 years of The Worst President Ever.

  14. This change of mind by James Hansen is another of the early benefits of the Trump-Effect. We can look forward to many more as Trump assumes power. Warmistas are heading for the exit door.

  16. Picking the land only data is interesting but not useful in considering global warming. The latest UAH data from November continues to be in the +0.4 range, well above the level before the latest El Nino. As J. Curry mentioned a few days ago, it will take some months to perhaps 5 years before we can judge whether or not the latest El Nino may be followed by a step change as may have occurred in the last (1997-89) El Nino).

    • The surface responds more promptly to forcings because surficial materials have a heat capacity about 1/4 of water. That is, water temperature is going to lag land surface temperature changes. If you want some insight on what is happening now, instead of waiting, it is best to look at land temperatures rather than sea surface temperatures or a combination that is buffered by the water temperatures.

      • The problem is noise. Any fast response component will show noise effects on the output much more prominently than a lagged, heavily damped component.

    • Yes, but the cooling reaction to the end of El Nino is likely to show up in the land data first, given the basic sluggishness/dampening due to the size of the ocean heat sync. If the effect works as expected, the Land+Sea data should ultimately decline as well, it’ll just take longer to see it. I think that’s the situation to which Dr. Curry refers.

      This is my assumption, please challenge if you have more information on this idea.

      • The deep seas (the ocean heat capacity) is all that really matters in this climate system state. The air component is a 2nd degree component. But as land dwelling creatures then that fast component, 2nd degree response, is important to us to as weather. The rest is climate arising from what is happening ing with OHC and those ocean cycles.

  17. A current theory, gaining much momentum, is that we now live in a “Post-Truth Society”. As ‘Old-School’, I want to stop the World and get off. We’re all headed backwards to oblivion fast if there’s no-one’s word we can rely on — excpet as viewed though a lens of “follow the money”.
    Back to the Four Estates … there used to be a separation of powers, and those independent powers were the foundations & corner-pillars of our society. Not any more, … and in my lifetime!
    Independent scientific thought has been hi-jacked by the political Pay-Masters: “You only say what we say you can say … or else!” to which there is a flip-side: toady-up to the Pay-Masters for a living. And so we have an unholy alliance between political opportunists and Snake-Oil Salesmen prepared to do anything, say anything for financial benefit. Truth, as in any war, against the people is the first casualty. George Orwell’s Big Brother would be proud of the way we are being strung-along by this cozy, mutually beneficial scam on the taxpayer which has little to do with scientfic probity & intellectual honesty.

    • Bill Clinton (and his sidekick The Algore) started us down the slippery slope of Post-truth. It accelerated some under GWB, Jr. Who did nothing to stop the climate alarmism lies.
      Then It took off wholecloth into The realm of whole Untruths with Obama.

  18. Would someone please advise our Prime Minister that his Carbon Tax is not needed yet. I sent e-mails in the past but I’m not a scientist so he does not listen to me. He oft repeated during his election campaign that his decisions would be guided by accepted science. Please, climatologists out there, help us!

    • Eh?
      Accepted science in Canadian Liberal speak, is that which transfers the wealth from your effort,into their pockets.
      You have to read in Liberaleeze, accepted by the Party.
      Or any other government action that forces money from taxpayers and enriches the chosen friends and family.

      Just Baffle them with BS, they seem to be used to it.

    • André, You don’t have to do a thing. Just watch Junior trying to square the circle, one minute talking up a carbon tax to discourage the use of fossil fuels, the next, approving the construction of 2 out of 3 crude oil pipelines to encourage their use, as we Canadians “transition” to a carbon-fee world. Yes, transition indeed! As if any company would invest billions in a project that will need decades to generate a payback while we “transition” off that product. We’ll be “transitioning” for a very, very long time. Wake me up when somebody discovers a renewable that has the energy density, reliability, storeability and transportability of fossil fuels.

    • Premier Mom is getting smacked real hard over electricity prices. Once it starts costing real money I expect the population will quit being apathetic about climate change. The Conservatives have to quit paying lip service to climate change and take advantage of the situation.

      When people across the country start paying much more for energy because of Trudeau Jr’s carbon tax, we have to make sure he gets the blame, not the provinces.

      Chretien and Martin cut back payments to the provinces. The provinces made cutbacks that hurt the population and got the blame. The provincial governments made some questionable decisions but the blame really belonged to Chretien and Martin, and they got off scot-free on that issue. Trudeau shouldn’t be able to take advantage of that kind of thing.

      • Jr. isn’t nearly as smart as his Dad. Folks forget that Sr. was involved with The Club of Rome. SK and MB are now “conservative”, Notley has about a 10% approval rating, so AB will go back to the right soon. Ontario is a mess, so could easily swing back. Hopefully Jr. is a one-term comedy act! He already has created a lot of damage. We are down to ~8 hrs. of low-angle sun so solar won’t be of much value. Snow is piling on top of the Panels. The windmills don’t function very well at low temp. The folly should be obvious before long. Suzuki – Canada’s answer to Hansen- isn’t have the same effect he once had.

  19. And the back-pedaling already in progress steadily, even frantically increases. They see the writing on the wall. And it spells T R U M P.

    • There is no change. Instantaneous reduction was never an option. What he has been saying is:

      “Given the fact that the fastest time scale to replace energy systems is decades, that means that we must get the political processes moving now. “

      • And, implied in that statement, Mr. Stokes, is the premise: decades are not too short a time scale.

        That is, Mr. Stokes, as MANY on this thread have pointed out, Hansen simply moved the goal posts to keep the game, going.

        Well, Hansen didn’t get the memo:

        CO2 UP. WARMING STOPPED.

        Game over.

      • This is probably pointless, but, dear mod, if you would please be so kind, please close my italics attempt after the words, “time scale.” Thanks!

      • “IT has always been his view that we urgently need to reduce emissions”

        Seems like he’s changed his mind, doesn’t it?

        It’s amazing how a regime change can focus the mind, wouldn’t you agree?

      • Mr. Stokes, the record (please read that back, court reporter…..) says otherwise:

        We have at most ten years—not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions” {Hansen} wrote …..

        You’ll be wondering where I found that. It was in the above article.

      • “It will be decades before that reduces GHG amounts.”

        With China, India, Turkey, Indonesia, Japan, Germany, soon the USA and also many other countries, totally disregarding the anti-CO2 scam, and continuing to build coal and gas fired power stations, it will be CENTURIES, not decades before global CO2 emissions even start a negative trend.

        And won’t the world’s plant life LOVE IT !!

      • I don’t see any dialback on Hanson’s part at all. What I see is, “Just because my previously published deadline(s) has(have) passed, don’t stop throwing money down this rathole. You MUST still expend billions on useless renewables and other Climate Change nonsense.” That’s what I read.

      • “ten years to alter fundamentally the trajectory of global greenhouse emissions”
        I agree with Cyrus. Whether you like what he’s saying or not, it hasn’t changed. Reducing emissions is urgent, in order to reduce the amount of CO2 in air within decades, and stabilize climate on a century scale.

      • Nick,

        “IT has always been his view that we urgently need to reduce emissions. ”

        Thanks for the LOL. I’m too tired to stay up and watch SNL. So thanks for filling in with the humor.

      • You are correct Ric. Nick Stokes is trying to sugar coat the atrocious actions, comments, and assertions by these people. Why skeptics are the same as war criminals, remember Nick ? Remember the wanted posters at the Paris Scam a Thon? Remember the language used to silence skeptics or actions taken by state attorney generals ? The threat was never some decades out. No price was too large to pay for saving the planet. Destroying the west’s economies, political systems and way of life was a given. Action had to be taken immediately, tipping points and run a way greenhouse conditions would turn the earth into a hellish cauldron within 10 years. The science was settled for all the deiners of gravity, evolution, mentally sick ( articles have been published), problem with authority, don’t understand science, and my favorite, ” you’re not a climate scientist ” , what papers have you published ? ” ….. I remember very clearly the last 20 years Nick. And like most here, have volumes of saved pdf ‘s stating such things.

      • Ric,
        I’m not sure why people think it is so important to parse Hansen’s statements so obsessively. But at least if it needs doing, they should be read. Hansen has always wanted urgent action to limit emissions. That is what is needed to get GHG amount down. But as he says in this statement as always, that won’t happen immediately – it would take decades. And, again as he says in the latest, if action on emissions is delayed, then more drastic action later will be needed.

        That’s Hansen’s view. It may well be that people won’t do it. That isn’t his fault. He tried.

    • Nick Stokes
      December 3, 2016 at 5:32 pm

      Why do you want to reduce emissions of CO2? Actual pollution, yes, but emissions of an essential trace gas? Are you nuts?

      CO2 going from 300 to 400 ppm has been a great boon to the world. Continuing to 500 and 600 would be better still.

      There is no correlation between the growth in CO2 since WWII and global temperature. From 1945 to 1977, CO2 increased monotonously, while earth cooled dramatically. Then for about 20 years, the planet warmed slightly, accidentally coinciding with a continued rise in CO2 at about the same rate. After 1998, temperatures were about flat, again despite the same monotonous increase in CO2. So climbing CO2 has coincided with 32 years of pronounced cooling, 21 years of slight warming and 18 years of no trend.

      So, no worries. But if continued CO2 gains does eventually barely warm the planet, that’s good, too. What catastrophic consequences do you imagine would befall the world at 500 ppm, for instance? Would have to be pretty bad to offset all the good done by greener planet enjoying more plant food in its air.

  20. A technical point, if anyone can help. I’m confused about the actual level of increase in CO2 since 1988. From the chart showing Hansen’s predictions we have this sentence:

    In reality, the increase in CO2 emissions by as much as 2.5%, which would correspond to the scenario above the blue curve.

    I don’t believe I’m nitpicking, as that doesn’t seem like an actual complete sentence. It’s a fragment. The word “is” is missing.

    Is 2.5% the actual CO2 increase? And is that 2.5% per annum? Because I thought it was a lot more in total.

    • Human CO2 Emissions

      (eyeballing it, it looks like a, ~ 60% increase since “Hansen’s Big Day” (1988))

      2010-2011 % Increase — CO2 Emissions

      (net: 12.8%)

      Looks like human CO2 was on a trajectory that flew off the end of Hansen’s chart many years ago….

      (sure is good he wasn’t assigned to Flight Command)

      CO2 UP. WARMING STOPPED.

      • Thanks Janice.

        So I’ll assume we’ve had MORE than the 1.5% increase in total yearly emissions that Hansen said would correspond to the blue line (temperatures going way up). And that 2.5% is the roughly correct figure. With that, according to Hansen, by now temperatures should have already went through the roof. The oceans should be almost boiling. But we got … nothing. Zero. Nada. No noticeable change in temperature or climate, at all.

      • Thank you, Clyde Spencer. Do you have the graph that shows your ~38% figure? My find (graph above) makes it look like CO2 c. 1988 was around 5,000. Thanks! (and, I believe you, that your figures are correct, just would like to have a better graph for the record, here)

      • You’re welcome, Eric. Good to see you back. Well, lol, I guess all that heat went to San Diego (where someone we know said it was, “Hot as HE{CK}!” lololol a couple years ago) — that comment stuck with me, just hit the funny bone that day. Thanks for a smile.

        :)

      • Thanks again Janice. I should be back every once in a while. I was kind of concentrating my attention on the general election instead of climate change. Now we finally got a real skeptic as president! (And GWB and GHWB were NOT skeptics!)

      • Eric Simpson December 3, 2016 at 3:55 pm
        Thanks Janice.

        So I’ll assume we’ve had MORE than the 1.5% increase in total yearly emissions that Hansen said would correspond to the blue line (temperatures going way up).

        That assumption is incorrect, Hansen’s projection for Scenario B was CO2 level of 400.5ppm.

      • Phil “That assumption is incorrect, Hansen’s projection for Scenario B was CO2 level of 400.5ppm.”

        Then why does the caption on the graph on this page say that the reality is the increase in CO2 emissions is 2.5%, which “would correspond to the scenario ABOVE the blue curve.” ?

      • Phil

        In other words, no matter what we do, even if we increase CO2 emissions through the roof, it would never go above 600ppm.

        The 600ppm level of CO2 does not seem like anything to be alarmed about. Indeed, it would seem to be a positive.

      • Eric,

        Yes, it’s hard at best to cook up any fossil fuel use scenario over the next century that gets us to 600 ppm. We’re unlikely to keep gaining two to three ppm per year, as gas replaces coal and oil in more and more applications. But even at two ppm per year, it would obviously take 100 years to reach 600 ppm.

        Salubrious as 600 ppm would be, 800 would be better, getting us into the zone that most pleases most plants, to include all trees and the majority of crops. As noted elsewhere, 1000-1300 ppm, as in greenhouses, would be best of all.

      • Chimp

        If our CO2 emissions are going to naturally nosedive I hope we can do something to keep those emissions up so we can reap the benefits of the ppm reaching at least 600ppm if not the higher levels that you would prefer. I’m usually against govt subsidies, but maybe, as people switch to natural gas and other energy sources, we should provide big subsidies for burning coal and oil to keep that CO2 level rising.

        And btw, keep in mind that the 1300ppm that you mention would be ideal is just over 1 part CO2 per 1000.

        1 part per 1000! This is what the fear-mongering Chicken Littles are squawking about!

      • Eric,

        Dunno if we’ll ever need to subsidize fossil fuel burning. The world is in a naturally warming trend, so CO2 should stay in the 300s ppm even if humans don’t burn any wood, coal, oil or gas. But we’ll continue to engage in CH4- and CO2-producing activities even if and when most of our electrical power and transport energy comes from nuclear, hydro, “renewable” and other sources.

        If wind and solar ever become economical, I hope that their dire environmental costs can be ameliorated somehow. It’s for the birds and the bats, if not the children.

      • Chimp,

        Speaking of wind power / and birds, I know that in the mountains by Big Bear Lake CA they close off a popular trail for nearly 6 months because they are worried that some hikers may inadvertently disturb the habitat of a few nesting Bald Eagles.

        But drive off the mountain into the desert below (near Barstow) and you find just hundreds of these massive & ugly windmill monsters that must be killing scores of Bald Eagles all the time. SHUT THOSE WIND MONSTERS DOWN!

        Here’s is a truly disturbing video, big bird KILLED by windmill:

      • Eric,

        It’s so hypocritical it’s sickening that windmills and solar farms are exempt from environmental and endangered species legislation.

        And the production of windmills and solar panels in China would never pass environmental muster here.

      • Eric Simpson December 3, 2016 at 5:14 pm
        Phil “That assumption is incorrect, Hansen’s projection for Scenario B was CO2 level of 400.5ppm.”

        I don’t know where they got their numbers from but the Hansen data shows 400.5ppm for scenario B. Perhaps you should ask the original poster?

    • ftp://aftp.cmdl.noaa.gov/products/trends/co2/co2_annmean_mlo.txt

      Mauna Loa shows growth in annual mean CO2 fraction from 351.56 ppm in 1988 to 400.83 ppm in 2015, a 27-year gain of 49.27 ppm or 14.01%. Thus, the average yearly growth in CO2 concentration has been 1.82 ppm. It has ranged from 0.48 ppm in 1992 to 3.05 in 2015. This El Nino year might equal or exceed last year. CO2 jumped 2.93 ppm in the El Nino year of 1998, but just 0.93 in 1999. The lowest growth in this century was 1.56 ppm in 2004.

      A Pinatubo effect might be evident in 1991, when CO2 gained only 0.99 ppm, and especially ’92. However the growth rate was already headed down, as it grew 2.29 ppm in 1987, 2.13 in 1988, 1.32 in 1989 and 1.19 ppm in 1990.

      • Thanks for those numbers, Chimp. There seems to be a lot of variance, but a report out (with graphic) last month suggests that the rate of CO2 growth has been flat at 2% for the 12+ years since 2002, while the rate of growth had been growing for decades before that: http://www.dailymail.co.uk/sciencetech/article-3917244/Is-greenhouse-effect-slowing-CO2-atmosphere-plateaued-12-years.html

        A possible explanation is that a growing biomass of plants are soaking up a lot of the CO2.

        I’ve also heard it predicted (as by Art Robinson) that even with growing CO2 emissions the limit on the parts per million (PPM) that we’d see would be ~ 600ppm. I don’t know what the reasoning was, but an increase to 600ppm with it positive effects on plants (and essentially zero affect on warming at these ppm levels) has got to be considered a big benefit to the planet.

      • The El Nino CO2 ‘burps’ are just Henry’s Law of physical chemistry. The effective rate is just under 2ppm with a very slight acceleration. More signiticant is that ~1/3 of all CO2 increase since 1958 (Keeling curve inception) has been since 2000, a period in which except formthe now rapidly cooling 2015-16 El Nino blip there has been no atmospheric warming detected by satellite or balloon.

  21. Every time alarmists say we have reached the point of no return or tipping point ,people lose any incentive to do anything. The proper interpretation of that observation is that it is futile to do anything as its now too late the world is doomed. We should totally spend our resources on the current generation as climate change has already gone too far to save the future. It is similar logic that caused the Australian government to sack a whole lot of workers at its chief scientific body the CSIRO who were told that because the science is 97% certain there was no need to continue to research it.
    That caused serious angst and unfortunately the government backtracked and rehired many of them. If you expect people to believe in what you say then understand that the consequences of this belief may be that the money tap will be turned off.

    • David, you are absolutely right. There fore I am going with their worst prediction, I am going out and enjoy myself before it is too late. ( the aussies rehiring the CSIRO was a joke, but I guess the golden hand shake must have cost more than keeping them on and at least you know where they are.)

  22. The motivation for Hansen’s switch is obviously the election of Trump. He never did believe his “doom is nigh” nonsense – he was just pressing for immediate action since he had a favorable dupe in the White House. Now that we’ve got a President who is going to show no inclination to drastically cut CO2 emissions for the next 4-8 years, Hansen needs to dial back the apocalypse. Otherwise, in 2020 or 2024 everybody is going to think it’s too late to do anything about the climate and we might as well go out enjoying ourselves.

    Here’s my climate-related prediction. As soon as there is another Democrat in the White House, Hansen – if he’s still alive – will again get on his street-corner soapbox with his end-of-the-world-is-coming routine about “tipping points” and “four year deadlines.”

      • +1

        they should have known they would be caught.

    • Agreed Kurt!

      I am surprised, I had begun to think that Hansen was showing age related senility; but this turn around show that he is coherent and attentive to current events.

      When a new leader takes the field, especially a no-nonsense impatient leader, all of the political gluteous maximus osculators, flexible fawners and climate fund parasitic sycophants; those with brains at least, immediately bow while pretending to respectfully celebrate the new leader’s words and ideas. All, while thinking Marcus Brutus thoughts. Et tu?

  23. “This El Nino year is proof positive that climate sensitivity Isn’t anywhere near what he once thought it was. Right now Global temperature has fallen towards the plateau set from the 1998 Super El Nino, especially over land as seen below..

    Well no.
    Global temps haven’t “fallen towards the plateau set ….”

    In fact this last November was the second warmest in the UAH sat temp record.

    “Combine that with the fact that even as carbon dioxide has been increasing, temperatures have not been upwardly tracking with it, but instead we’ve seen El Niño driven spikes in temperature, which have nothing to do with CO2 sensitivity. The natural variation of the system still rules the climate.”

    Why would you expect “temperatures to track with it” (in a monatomic fashion) ?
    There is a natural variation. On top of the AGW signal.

    For the same reason that you say the EN has raised GMST’s, then the previous 18 odd years of predominantly -ve PDO/ENSO/LN regime suppressed them.
    You can’t just credit the heat from the cycle and deny the cooling side.
    Either both are true or neither are.

    Also this is the history of the PDO regime vs GMST.
    Please do notice that all varieties climb along with the temp.

    So generally speaking we have a system that receives solar energy, stores it and then,in cycles, returns some of it to the atmosphere, and all the while (long term trend) manages to make the atmosphere warmer.
    Whilst also heating the deeper ocean…..

    If the sun is not powering warming (it isn’t – ask Leif), and as you imply instead ENs are, then the oceans would be cooling.
    A transfer of heat from ocean to atmosphere.

    http://www.nodc.noaa.gov/OC5/3M_HEAT_CONTENT/

    • What AGW signal?

      No such thing is in evidence globally. Whatever warming has occurred since CO2 took off after WWII is well within normal bounds. Previous warming cycles since the Holocene Optimum have lasted longer and gotten hotter.

      For that matter, for practically the first half of the monotonic postwar CO2 rise, earth responded by getting colder. So much so in fact that in the ’70s the scare was the coming return of the ice sheets, not global warming.

      Humans have made cities and some other parts of the planet warmer, but overall, not so much, and not measurably from the GHE. So far, more CO2 has been beneficial to plants and other living things.

    • Dear Mr. McLeod,

      (in your ear) You mistakenly posted the wrong graphs. They (##1 and 2) SUPPORT the statement you (apparently) intended to contradict:

      Global temperature has fallen towards the plateau set from the 1998 Super El Nino….

      (btw: we saw you slip that card into your sleeve — well, I thought you’d be better off knowing, you want to get hired for more gigs, don’t you? — i.e., no one was fooled by your “warmest in the UAH record” sleight of hand.)

      Janice

    • Fascinating stuff ToneB.

      You say that “In fact this last November was the second warmest in the UAH sat temp record.”

      So what will it be next month and next year, and how many of the next 10 will be higher or lower. Time to make a prediction based on your knowledge of the world and they see how it turns out. Of course it will help for you to point out your previous predictions and say how they turned out.

      You end with “A transfer of heat from ocean to atmosphere.”

      Tell us how the heat got into the oceans in the first place and name three physical phenomena which would control the rate at which the transfer occurs.

      Oh, and yes I would expect there to be a measurement somewhere which points to monotonic increase in some quantity as support for the CAGW hypothesis. Drawing straight lines on cyclic and noisy data doesn’t count.

    • Toneb,

      You ask, “Why would you expect “temperatures to track with it” (in a monatomic fashion) ?”

      Umm, because that’s what the models show. You know, the ones that predict climate catastrophe right around the corner. No, not that corner, the next one…

      • But.but…haven’t we already passed the “tipping” point(s?) that Hansen and the rest of the Muppets had projected?
        Yet, here we still are commenting on WUWT.
        Perhaps all those “tipping points” were, what’s current the term?, “Fake News”? “Political Science”?

    • Toneb, that is all way to systematic and logical for the choir here. They prefer the tabloid:

      “SHOCK:” nonsense; anything that confirms their ideological bias.

      But hats off to you for trying.

    • Nice bit of bafflegraph there. You must have read “How to lie with statistics”. Three different sources, to different time scales, apparently using linear least squares on self-correlated data, one graph with multiply corrected figures, homogenization, different periods, Well Done! it’s almost believable

    • Speaking of “cherry-picking” intervals, your GISTEMP graph with the meaningless linear trends completely obscures what happened before 1977 (try starting this in the late 50s, for example). And then notice that stopping somewhere around 2007 obscures how flat that period from 1997/1998 is, up to the latest El Nino.

      Net, net, you took the step function that was associated with the major El Nino in 1997/1998 and used it to pretend there is some sort of pure linear trend over the last 50 years instead of the variation we’ve experienced (with a slow upward trend) over the last 100+ years. And of course, even the 0.6 degrees C you noted over the fifty year period only works out to 1.2 C/century. And CO2 has increased how much over that period? And therefore the sensitivity is what?

      • And guess who Troll Tone B is trying to smear (use to create confusion)?

        (for those new to WUWT, “Tony B” is a fine science realist scholar’s scholar who regularly posts impeccably well-founded-in-science comments)

    • How many of the ocean buoys are present in the Arctic? Where is it that sea ice absence has allowed the oceans to cool? Oh yeah, the Arctic. Did you also forget about the paper showing upward vertical movement of energy in the oceans? Is that why you limited the data to 700 m?

      This is what happens when a person doesn’t understand the data he is using. ToneB is a perfect example of why bias so easily destroys ones critical thinking ability.

      • Richard M,

        Critical thinking is a handicap if you are a climate change believer.

        The Climate Holy trinity for the Left is:
        -The IPCC (the gospel-spewing savior)
        -The UN (the benevolent Father)
        -The Keeling Curve (the omnipresent ghost affecting all life).

    • i stick with Bob Tisdale’s theory: i suspect the global temp will soon show a small step up. (though this time signs are a bit contradictionary: arctic sea ice very low, but greenlands ice melting is also very low with a record whopping + 100 Gton far above any recorded gain anomaly. so not sure if it will)

      if the temp will make a step up around the +0.4 anomaly mark that makes El nino driving the warming….

      that gives Leif a big problem: the only driver of El nino is…. the sun. (and cloudiness)

    • Toneb

      You nailed it for once, it is a natural warming cycle and see you didn’t even have to mention agw to explain it.

  24. Clearly, Hansen must see that “the gig is up” and that he has to find a new way of spinning himself into some kind of new relevance and concomitant funding.
    The GOOD NEWS for us is that this is very clear evidence — from no less than ***HANSEN*** that the cracks in the whole crumbling edifice of AGW theory, practice, politics and funding are so fast appearing that die-hards like him are looking for a new start.
    Sorry, buddy, go tote sandwich-boards to earn a crust … you are irredeemably tainted with the label: ‘Snake-Oil Salesman’.

  25. Guardian piece from July 31, 2008:

    https://www.theguardian.com/environment/2008/aug/01/climatechange.carbonemissions

    “Time is fast running out to stop irreversible climate change, a group of global warming experts warns today. We have only 100 months to avoid disaster. Andrew Simms explains why we must act now – and where to begin…….”

    100 months from the end of July, 2008 was Nov. 30, 2016 (if my math is right). Terrific, so I have been getting all set for runaway climate change this year and was planning on attending Ms. Schmidt’s Good Grief therapy sessions out in Utah.

    And now Hansen comes along and tells us that we’ve been given a bit of a reprieve from the Nov 30th deadline this year. I mean, what’s a body supposed to do here? End-of-the-world gloom and doomers have been persistently wrong throughout human history, but climate alarmists can’t possibly be repeating history here, can they?

    Noooo, of course not. (sarc).

    • Exactly. Hansen wants to glean favor from the skeptics by being the idiot that finally learned the real science. If the political worm turned, it would bet a given that he would pivot back to alarmism. He is a political whore.

  26. Hansen is hedging his bets. Nothing to see here, folks, he says.

    How much of our money has this man caused to be wasted on this CAGW sc@m? How many people has he driven temporarily insane with fear because of his lies? He’s got practically the whole elite world marching to his tune and now he wants to change this tune a little.

    We want our money back, Hansen.

    • He is not changing his tune one iota. That is purely the bias you see when you look at all this through the WUWT prism.

      • “He is not changing his tune one iota. That is purely the bias you see when you look at all this through the WUWT prism”

        Yeah, yeah, yeah…

        You just go right on believing your hokey schtick, tony.

        Jim Hansen Climate Change: On the Edge
        Published on Friday, February 17, 2006, by the Independent/UK
        Available here: http://www.commondreams.org/views06/0217-22.htm
        Original here: http://news.independent.co.uk/environment/article345926.ece (truncated and requires purchase).

        In 2006: “How long have we got? We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree. … we cannot wait for new technologies like capturing emissions from burning coal. We have to act with what we have. This decade, that means focusing on energy efficiency and renewable sources of energy that do not burn carbon. We don’t have much time left. (my bold)”

        Jim Hansen, 2016: “The ponderous response of the climate system also means that we don’t need to instantaneously reduce GHG amounts. … the time scale on which we must begin to reduce atmospheric GHG amounts is measured in decades,… (my bold)”

        Also in the 2006, Independent: “Once a sheet starts to disintegrate, it can reach a tipping point beyond which break-up is explosively rapid. The issue is how close we are getting to that tipping point. The summer of 2005 broke all records for melting in Greenland. So we may be on the edge. (my bold)”

        Hansen’s changed his tune many iota.

        Here’s probably why: catastrophe predicted within a decade of 2006. Let’s see, that’s umm … calculating … 2016! Greenland icesheet: still here. Air temperature change 2006-2016: approximately zero (El Niño apart).

        2006: On the edge
        2016: Ponderosity

        He’s back-sliding.

      • Tony,

        So, claiming settled science, predicting catastrophe right around the corner ans shouting that “We’re on the Venus Express, the oceans are going to boil and we’re all going to die!” isn’t one iota different from saying there is much we don’t know about climate and that there’s plenty of time. What color is the sky on your planet?

      • Through the prism of reality, here is what Hansen said in 2009. Compare and contrast with now:

        In his book Storms of my Grandchildren, Hansen issued this dire warning: “[I]f we burn all reserves of oil, gas, and coal, there is a substantial chance we will initiate the runaway greenhouse. If we also burn the tar sands and tar shale, I believe the Venus syndrome is a dead certainty.” (In fact it would take ten times as much CO2 as could be released by all the presently accessible fossil fuels to have any chance of runaway heating, even by the accounting of climate alarmists.)

        http://news.nationalgeographic.com/news/2013/13/130729-runaway-greenhouse-global-warming-venus-ocean-climate-science/

        He said that burning of fossil fuels leaves earth in “imminent peril”. He suggests that millions of species, and humanity itself, are threatened. The book title refers to the ferocious and stormy weather events that will occur next generation if fossil fuel use continues in the way it has.

        Hansen claimed that we immediately need to cut back atmospheric carbon dioxide emissions to stabilized at 350 ppm or less, in order to avoid environmental disasters for generations to come. He advocated prompt phaseout of coal plant emissions, plus improved forestry and agricultural practices.

        That was then. This is now. The urgency is gone with the wind.

      • Ok you got me. He’s a contrarian.In fact, wasn’t he talking about the looming ice age back in the seventies?

      • Tony,

        I don’t know what Hansen’s opinion was about global cooling in the 1970s, but his colleagues at NASA and NOAA publicly expressed concern about the looming return of ice sheets.

        Academia of course was also infected with the possibly lucrative fear. In 1974, the year after I graduated, my Stanford profs Ehrlich and Holdren (Obama’s science advisor) warned of coming icy doom. Ditto Schneider and many others who later jumped on the global warming band wagon, or should I say gravy train?

  27. The quantitative absurdity this whole lost generation is based upon is Hansen’s claim , http://cosy.com/Science/Hansen.avi , that Venus’s surface temperature , 225% ( 400K > ) the gray body temperature in its orbit is due to some electromagnetic , ie : spectral , phenomenon . Quantitatively absurd by the most classic experimentally founded and verifiable computations . ( I’m waiting to see some brilliantly simple demonstrations of these classic quantitative laws . )

    Yet the entire GHG paradigm asserts that some cascade of spectral filters trap the 33K difference from the crudely estimated radiative balanced temperature of 255K .

    SHOW ME .
    Either the equations or the experiment . Some variation on Ritchie’s 1830s experiment should do . Nothing complicated — just demonstrate it in a 1 dimensional sandwich between a heat source and sink .

    You can’t get the equations to balance without the terms for the other macroscopic force .

    • Even if, as it would seem, we live in a ‘Post-Truth’ world (thanks in large to the Mannipulators of Climate
      Science), the irony is that TRUTH becomes The Gold Standard.
      And the ULTIMATE TRUTH can only be determined by a return to the old-fashioned principles of rigorous
      Scientific challenge, repeatability of results and vigorous debate, etc. For Heaven’s sake, Einstein is still being questioned (albeit at the margins) but *his* science has never been settled, has it? I posit that *no* science is *ever* “settled”, so who are these sinecure-seeking, Charlatan, Snake-Oil Salesmen to persuade us otherwise?
      I think we ‘lost the script’ shortly before the onset of the AGW debate …. perhaps by the back-room politco/scientific spin-doctoring during the mad-cow scare. The Pay-Masters told the Scientists what to say to further their political ends. Goodbye scientific integrity.
      The Scientists, not being short of brain synapses, twigged-on that it is a two-way street … and here we are with this unholy alliance between opportunistic politicians and sinecure-seeking pseudo-scientists (a pox on both of them!)
      Let TRUTH be held to the highest levels of testing, not something gleaned from pseudo-scientists, politicians and — of course — their ever-sensationalist parroting friends — the media.

    • Agree the whole Venus/CO2 thing is totally messed up but it is the foundation of the AGW movement, damn you Carl Sagan, it’s the massive Venutian atmospheric pressure creating supercritical C02 at the surface, basically the surface of Venus is an liquidy ocean-like CO2, as any rookie scientist knows you heat a liquid up and it veerrrrrry slowly rises due to buoyancy, hardly any convection at all. But on Earth when you heat up air or vaporize water at the surface it rises very fast that’s why nearly 90% of heat transfer is due to convection. But the fake news is that is Venus is hot due to CO2 not pressure and since that is the official propaganda try to oppose it and you get banished.

      • Venus ~95% CO2 atmosphere, HOT! Mars, 95% CO2 atmosphere, COLD! Venus, ~90 x earth atmospheric pressure/mass. Mars ~0.6 earth atmospheric pressure/mass. Gas laws apply. CO2 insignificant to temperature.

      • Yes . But it still needs to be emphasized that the force which “causes” the pressure is that only other macroscopic force : gravity . That pressure , “lapse rate” , whatever , doesn’t just happen . It is due to precisely quantifiable and quantified non-optional gravitational force . It cannot be left out of the energy balance equations . And the trade-off shows itself as kinetic thermal energy . Others , eg : HockeySchtick , have worked out the equations . I’m totally focused on finding the market for my 4th.CoSy , but that does seriously include people interested in modeling planetary physics as I discussed at the Minnowbrook2013 APL Implementers Conference so I’ll wait for others to motivate work in that direction .

        The bottom line , tho , is that the notion that a spectral GHG effect is responsible for the ~ 33K difference between our “radiative balance” temperature and our surface temperature is simply , classically , and experimentally provably false . It defies the Divergence Theorem . It fails undergraduate physics and Hansen should have been laughed out of the room for incompetence when he first made his claim . Instead it has become a paradigm which has retarded a generation .

        The only effect changes in CO2 or other GHGs have on our temperature is the de minimis changes they may make at these already optically saturated levels in our spectrum as seen from outside . No “tipping points” around except the one at 273.15 .

  28. Anthony

    Interesting RSS plot: sort of looks like the area under the 1998 El Nino peak is about equal to area under the 2015/16 peak, which would make sense if approximately the same total energy was released.

    • Jane,
      Compare for yourself the data on 2015/16 vs. 1998 El Ninos.

      (Mucho thanks to Bob Tisdale and his blog.)

  29. Anthony Watts commentary:
    I think Dr. Hansen has come to the conclusion that climate sensitivity is not as sensitive to carbon dioxide as it was once thought to be in his original a, b, and c scenarios from 1988. We’ve noted previously, that it is 150% wrong.

    Mr Watts, this relationship is extremely easy to map-out, and should have been the starting point of any serious research. You should commission a simple article that Simply take a data set of Temperature and CO2 and add on the marginal energy absorption of atmospheric CO2. That last data is easily found using MODTRAN.

    The δC / δW/M^2 doesn’t make much of a case for CO2 to be the cause.


  30. Just look at this chart. The ΔC falls between 1880 and 1910, yet the ΔW/M^2 increases. The ΔC then climbs between 1910 and 1945, and the ΔW/M^2 increases. The ΔC then falls between 1945 and 1985, and the ΔW/M^2 increases. The ΔC then climbs between 1985 and 2016, and the ΔW/M^2 increases. CO2 trapping W/M^2 can result in either falling or rising temperatures. That is a problem.

    • @Nick Stokes, this is a very very very easy problem to solve. Simply calculate the ΔC°/ΔW/M^2. You simply can’t tie CO2 to ΔC° and CO2’s ΔW/M^2. If you can’t demonstrate that the additional energy trapped by CO2 results in higher temperatures, you can’t make your case.

      • Greg,
        “As you well know it is the temperature record which has been adjusted to fit the earlier claims, if you are going to use GISS LOTI.”
        What I very well know is that it has no dependence on adjustments, which in any case are not made by Hansen, but NOAA. I know that because I calculate global temperatures myself, using unadjusted GHCN temperatures. And it makes no difference. TempLS in green, GISS L/O in brown:

      • How is that different from standard sensitivity, expressed as °C/(forcing in W/m2)?

        The numbers don’t add up. There is extreme variability with the Δ°C/ΔW/M^2, in fact at some times it may be (+) and at others (-). There must be other factors driving temperature, otherwise,there would be a linear relationship. There isn’t.

      • “Nick Stokes December 3, 2016 at 4:06 pm

        How is that different from standard sensitivity, expressed as °C/(forcing in W/m2)?”

        Forcing? What is being forced? Theory? And you say science is on your side? Total BS!

      • Nick writes

        TempLS in green

        Most closely tracking scenario C which is Hansen’s prediction for rapid decline in CO2 emissions. Reality is much closer to scenario A which is increasing CO2 emissions. Scenario B is slowing rate of use. Are we doing that? No. Just ask China and India…

      • Although I’ll admit that the numbers Hansen used (A:410ppm, B406ppm, C~370ppm – assuming you’ve quoted them correctly at your site) would put the scenario closer to B. So basically Hansen over estimated the warming as well as over estimating the emissions. in terms of “naming” the scenarios.

      • “Hansen over estimated the warming as well as over estimating the emissions. in terms of “naming” the scenarios.”
        The scenarios are more complex than can be covered by simple tag names. They allow for changes in CH4, CFCs, and for volcanoes (at least B and C). CH4 fell well short, for CFCs, the effects of the Montreal protocol came after 1988. Hansen’s program predicts the effects of GHG gases. It does not predict the amounts that might be put there by emission. It does not even relate emissions to concentration.

        Without comparing the evolution to the actual numbers input, you can’t say that he overestimated warming.
        As I said above, those gas numbers were posted here for a similar paper the following year. They don’t exactly correspond, but are close.

      • Nick writes

        Without comparing the evolution to the actual numbers input, you can’t say that he overestimated warming.

        Nonsense. You can see his projection is tracking most closely to scenario C and that was based on about a 370ppm CO2 calculation. There is no way the other GHGs make up for that difference.

        Hansen’s projection was a fit based on the current warming rates in his day. That’s what happened and explains his results perfectly.

      • Nick writes

        Hansen’s program predicts the effects of GHG gases. It does not predict the amounts that might be put there by emission.

        Hansen had another program to predict the CO2 emissions. Hence why they’re output to a ridiculous 12 decimal places. I’ll warrant it was very simplistic.

        From Hansen’s paper

        The range of climate forcings covered by the three scenarios is further increased by the fact that scenario A includes the effect of several hypothetical or crudely estimated trace gas trends (ozone, stratospheric water vapor, and minor chlorine and fluorine compounds) <b<which are not included in scenarios B and C.

        So…nope. You cant blame the effect of CFCs in his scenario B and C projections.

      • Oh and I see that Hansen predicted a positive feedback from stratospheric H2O. You asked who had assumed water vapour would increase in the stratosphere (in the face of it actually being a negative feedback and decreasing in reality) and now you have the answer.

      • TTTM,
        “You cant blame the effect of CFCs in his scenario B and C projections.”
        No. Here are the headings of the gas conc file I posted:
        CO2_A N2O_A CH4_A CFC11_A CFC12_A CO2_B N2O_B CH4_B CFC11_B CFC12_B CO2_C N2O_C CH4_C CFC11_C CFC12_C

        CFC11 and 12 were in all scenarios. Here are the actual numbers for 2015, from that 1989 file, with CFC nums from here:

        		CO2  	N2O  	CH4  	CFC-11  	CFC-12
        Scen A  403.0 	0.34    2.78  	   1.398  		2.4
        Scen B  398.6  	0.33     2.28  	   0.61  		1.06
        Scen C  367.8 	0.31     1.91  	   0.26  		0.51
        Actual 	399		0.328  1.83	  0.23		0.52
        

        CO2, N2O was scen B, the rest Scen C

      • Nick writes

        CFC11 and 12 were in all scenarios.

        OK, I’m willing to accept “minor chlorine and fluorine compounds” doesn’t include CFCs as a whole.

        What’s going on with Hansen’s Figure 2? He appears to be implying that the CO2 forcing for lets say scenario A is about 0.8W/m2 by 2050 but when you add the other trace gasses and even add the negative impact from aerosols, the forcing is about 2.2W/m2

        How does that work exactly?

      • Obviously I mean delta T rather than W/m2 but it looks like he’s attributing about 2/3 of the warming to the trace gasses??

    • No Nick , that’s a disingenuous claim. As you well know it is the temperature record which has been adjusted to fit the earlier claims, if you are going to use GISS LOTI.

      What Hansen said in 1988 was NOT based on rigging the SST record by applying NMAT “corrections” to daytime SST.

      Post hoc adjustments to SST do not count in assessing how accurate his predictions were, not to mention the constant ‘warming up’ of the land based data as well.

      Also your blue line “GISS Ts MET stations” ( ie the land record ) is not comparable to the “global temperatures” plotted from Hansen.

      With exception of the recent spike, the closest match seems to be “scenario C” which is the drastic reduction on CO2 output starting in 1990 which just did not happen. Basically AGW is busted.

      Thanks for the graph.

      • Greg,
        Reply above
        The test for scenarios is what happened. Scearios were defined in terms of forcing – GHG concentrations. In fact, what evolved was between B and C. Discussion here.

      • Nick StokesDecember 3, 2016 at 4:46 pm
        ” I calculate global temperatures myself, using unadjusted GHCN temperatures.”
        GHCN temperatures are already adjusted by the time you get them to use Nick. Tell the truth for a change.

      • “Nick Stokes
        The test for scenarios is what happened. Scearios were defined in terms of forcing – GHG concentrations.”

        That’s not accurate. Hansen’s three scenarios were distinguished by different GHG emissions rates, not rates of increasing concentration in the atmosphere. Those are two different things. Global emissions rates since 1988 met or exceeded Hansen’s scenario A, in which he assumed a 1.5% annual increase in emissions from 1988. At that rate, in the 17 years from 1998 to 2015, CO2 emissions would have increased by a factor of 1.49. This article pegs actual emissions increase since 1990 at 50%: https://insideclimatenews.org/news/19052016/global-co2-emissions-still-accelerating-noaa-greenhouse-gas-index.

        Temperatures rose nowhere near what Hansen’s model predicted for our actual growth in emissions.

        That’s not accurate. Hansen’s three scenarios were distinguished by different GHG emissions rates, not rates of increasing concentration in the atmosphere. Those are two different things. Global emissions rates since 1988 met or exceeded Hansen’s scenario A,
        As stated in Hansen et al 1988 scenario A assumed continuing exponential trace gas growth, B assumed a reduced linear growth of trace gases, and C assumed a rapid curtailment of trace emissions.
        Hansen’s projection for scenario B was CO2 by 2016 of 400.5ppm.

      • “GHCN temperatures are already adjusted by the time you get them to use Nick. “
        No evidence, and easily refuted. I have written a post here setting out how BoM goes from AWS numbers posted every half hour (within minutes) to a monthly file, CLIMAT form, and so to GHCN unadjusted. You can check at every stepo. But of course, no-one is interested in that. More fun just to rant.

      • “Hansen’s three scenarios were distinguished by different GHG emissions rates, not rates of increasing concentration in the atmosphere. “
        No. Emission ideas inspired them, but you can’t use those for computation (or not in Hansen’s day). You need concentrations, and they have been posted. Here is Hansen setting that out:

        The actual numbers (gas conc) for the scenarios are given here. That’s from a paper a year later, but using the same scenarios.

      • “Phil:
        As stated in Hansen et al 1988 scenario A assumed continuing exponential trace gas growth, B assumed a reduced linear growth of trace gases, and C assumed a rapid curtailment of trace emissions.”

        You need to read the Hansen’s paper more carefully. These are the exact words on the assumptions of his scenario A: “Scenario A assumes that the growth rates of trace gas EMISSIONS typical of the 1970s and 1980s will continue indefinitely. The assumed annual growth averages about 1.5% of annual EMISSIONS.”

        Nick Stokes:

        “Emission ideas inspired them, but you can’t use those for computation (or not in Hansen’s day). You need concentrations.”

        Emissions “ideas” didn’t “inspire” the scenarios (whatever that gibberish means). The emissions growth rates WERE the scenarios. Whatever CO2 concentrations resulted from those scenarios were, like temperatures, an output of the scenario, not an input. Otherwise, he would have included those in the paper itself. And the portions of appendix B that you don’t quote affirms again that the assumptions of the scenarios are in the growth of emissions, not atmospheric concentration.

        You’re just engaging in sophistry to try to explain away the fact that his predictions of what would occur for what he testified under oath before Congress was the “business as usual scenario” was wildly inaccurate. And do you really want to be arguing argue that Hansen’s knowledge of the climate system wasn’t good enough for him to get something relatively simple right, like what atmospheric CO2 concentration would result from a given rate of growth in emissions, but that he understands the climate well enough to get the insanely hard stuff right, like what the temperature curve is going to look like for a given rise in concentration. What you see as some kind of validation for a wrong prediction is just an ex post facto correlation to try to salvage something from the failure.

        “Phil:
        As stated in Hansen et al 1988 scenario A assumed continuing exponential trace gas growth, B assumed a reduced linear growth of trace gases, and C assumed a rapid curtailment of trace emissions.”

        You need to read the Hansen’s paper more carefully. These are the exact words on the assumptions of his scenario A: “Scenario A assumes that the growth rates of trace gas EMISSIONS typical of the 1970s and 1980s will continue indefinitely. The assumed annual growth averages about 1.5% of annual EMISSIONS.”

        I have read it very carefully, many times, my statement to which you refer is accurate.

        You’re just engaging in sophistry to try to explain away the fact that his predictions of what would occur for what he testified under oath before Congress was the “business as usual scenario” was wildly inaccurate.

        His projections for CO2 in 2016 were:
        A 405.4ppm, B 400.5ppm, C 367.8
        M-L data Oct 2015 398.3ppm, Oct 2016 401.6ppm
        Not bad for a estimate made 30 years ago!
        As he stated at the time he expected that scenario B was “perhaps the most plausible of the three” and that scenario A “must eventually be on the high side of reality”, also that scenario A included some speculative, “crudely estimated trace gas trends” which the others did not.
        His estimates for CH4 and CFCs are better matched by scenario C, although after plateauing after 2000 CH4 is now growing again. (CH4 fixed at 1916 ppb, actual 1834ppb)

      • “Phil

        I have read it very carefully, many times, my statement to which you refer is accurate.”

        No – it’s not accurate. Your statement was that Scenarios A-C related to growth of CO2 concentrations in the atmosphere. Hansen’s scenarios were for different options for man-made emissions, not different rates of growth in ppm of CO2 in the air. Hansen was asked specifically about this when he testified before Congress, and he confirmed that scenario A predicted what would happen if GHG emissions continued on their “business as usual” exponential growth. The resulting increase in CO2 concentration in the atmosphere was, like temperatures, a result of the scenario, not part of what was assumed in the scenario.

        “His projections for CO2 in 2016 were:
        A 405.4ppm, B 400.5ppm, C 367.8
        M-L data Oct 2015 398.3ppm, Oct 2016 401.6ppm
        Not bad for a estimate made 30 years ago!”

        No – it’s a lousy prediction. You’re illogically conflating his predictions of CO2 concentration in the atmosphere for ALL the emissions scenarios and trying to compare that entire range with what actually occurred. Read the passage of yours I just quoted more critically this time. The CO2 concentration in 2016 that actually resulted from the world continuing its exponential growth in CO2 (scenario A) was less than what Hansen thought it would be if CO2 emissions were held to linear instead of exponential growth. No reasonable analysis would call that “not bad.” If your bar for being “not a bad estimate” of actual CO2 growth is so low that hitting anywhere within the range of any of the three estimates is good enough, then what exactly was the point of differentiating CO2 concentrations for each scenario in the first place?

        “As he stated at the time he expected that scenario B was “perhaps the most plausible of the three” and that scenario A “must eventually be on the high side of reality”, also that scenario A included some speculative, “crudely estimated trace gas trends” which the others did not.”

        Stop taking quotes from Hansen’s paper out of context. With respect to scenario A, his only caveat was that, since it relied on continued exponential growth in CO2 emissions, it must”eventually” be on the high side of reality as we started running out of fossil fuels. Hansen’s vacillations between scenarios A and B related to the long term projections, not the short term projections. We clearly haven’t felt any limit on fossil fuel production in the last 30 years – inventories of fossil fuels are continually increasing, and again, the real world output most closely followed scenario A except for one major volcanic eruption, which even the climate alarmists admit would have only shown a transitory effect for about five years.

        And even if you were to assume that Hansen’s’ statement about Scenario B being “perhaps” the most plausible (lovely weasel word, that) related not to the very long term projections but even to the short term temperature predictions, what does it matter? We now know that the actual growth in CO2 emissions – being by far the most important greenhouse gas considered by Hansen – met or exceeded what was considered by Hansen to be Scenario A. What Hansen considered to be the most likely emissions scenario in 1988, before he could have known what would happen, is not relevant to judging the accuracy of the prediction after the real world results have come in. You’re just trying to seize on this weasel language to support your revisionist history of Hansen’s predictions.

      • “an output of the scenario, not an input”
        They may be an output of the scenario. But they are the input to the GCM, and the only forcing input suplied. Not emissions, or terms like “business as usual”. You can only assess the performance of the GCM in terms of the actual numbers it is given to work with. And they were as Phil describes.

    • If I’m reading the temperature annotations on this old graph correctly, are you showing that the peak of the current El Nino was 0.5 degrees C higher than the 1998 El Nino? That’s certainly not consistent with the RSS/UAH data, and seems larger than the (less accurate) land/ocean sets as well – and shows dramatic increase starting in some time around 2012 – does that make sense? I know it helps in trying to make your case, but you’re not providing needed information – for example, which “scenario” of Hansen’s actually happened?

      • ” you showing that the peak of the current El Nino was 0.5 degrees C higher than the 1998 El Nino?”

        Yes, that is what GISS says, and other surface indices.

        I’ve discussed what scenario happened here:

        ” The only test that matters is what actually occurred. And the test of that are the actual GHG concentrations that he used, relative to what we now measure. The actual numbers are in files here. Scenario A, highest emissions, has 410 ppm in 2015. Scen B has 406, and Scen C has 369.5. The differences between A and B mainly lie elsewhere – B allowed for a volcano (much like Pinatubo), and of course there are other gases, including CFC’s, which were still being emitted in 1988, but not much now. Measured CO2 fell a little short of Scenarios A and B, and methane fell quite a lot short, as did CFCs. So overall, the actual scenario that unfolded was between B and C. “

    • “In fact, Hansen was predicting surface air temperature. And his prediction has stood up very well.”

      Yeah, if you go by that bastardized surface temperature chart, custom made to make the predictions look good.

      Comparing data using a bogus chart just gives you bogus conclusions.

        Well, I don’t think you are using unadjusted data. See below.

        “10. “Data adjustment” is used to continue the perception of global warming:

        For the first several years of my research I relied on the climate data banks of NASA and GISS, two of the most prestigious scientific bodies of our country. After years of painstaking gathering of data, and relentless graphing of that data, I discovered that I was not looking at the originally gathered data, but data that had been “adjusted” for what was deemed “scientific reasons.” Unadjusted data is simply not available from these data banks.”

        Would like to have your thoughts on this. And the thoughts of all the other people who use this data to do their work.

      • “Would like to have your thoughts on this.”
        As far as Biezen is concerned, this is simply untrue:
        “Unadjusted data is simply not available from these data banks. Fortunately I was able to find the original weather station data from over 7000 weather stations from around the world in the KNMI database. (Royal Dutch Meteorological Institute).”

        He hasn’t looked. Unadjusted GHCN (qcu) is available here in the same directory as adjusted. That’s where KNMI (and most others) get it. And there is vastly more unadjusted data in GHCN daily.
        As mentioned above, I use GHCN unadjusted to calculate a global index, with very little difference to GISS etc. I have just written a post here which traces through how AWS numbers posted by BoM every half hour are shown in real time, transmitted to publicly available WMO files (CLIMAT) and to GHCN unadjusted, all without change.

      • ” Unadjusted data is simply not available from these data banks”

        Well, for some reason, noone who uses these data banks wants to comment on the claim that they are not unadjusted data.

      • “Well, for some reason, noone who uses these data banks wants to comment on the claim that they are not unadjusted data.”
        I comment, as linked above and elsewhere. Others may think the claims just too unsubstantiated (as they are). The thing is, if you really want to press this stuff, you need a demonstrated example. The data is all out there. Just find a case where you think data presented as unadjusted is not so. Then there is something to work on.

      • Ppm T T ppm

        As an example Nick. More changes have been made since. Notice how the temperature was adjusted upwards from 2009 … and so on until I stopped at 1960. In a previous post I quoted the ppm for one year and the the response was ” where did you get that. That’s not what I have “… implying that any research I do is invalid by using incorrect data. Would you care to explain why temperatures were adjusted ? All data is from NOAA as posted.

        Sorry about that Nick. I see you did reply. It’s funny, I didn’t see any reply from you at the time I posted, even though it looks like you posted four hours before I did.

        “Others may think the claims just too unsubstantiated (as they are). The thing is, if you really want to press this stuff, you need a demonstrated example.”

        Maybe we need to get Mike van Biezen, the author of the article, to come over here and defend his claims. I’m thinking that might be interesting.

    • And his prediction has stood up very well…..

      So you’re saying we no longer need to reduce CO2 levels?…..what his prediction was based on

      • Nick, GHCN temperatures are already adjusted by the time you get them to use Nick. Tell the truth for a change.

      • NOAA is so corrupted that even its raw “data” can’t be trusted. Its flunkies have their thumbs on the the thermometers, as it were.

      • Nick,

    • “And his prediction has stood up very well.”

      Aren’t those NOAA/GISS “adjustments” just dandy :-)

      Fabrication at its worst.

      • Science is the argument, not the papers, Nick. You’ve refuted none of my analyses, not one.

        I’ve also debated top climate modelers in my reviews, and have shown they’re widely incompetent. Maybe that should be wildly incompetent, because they apparently know nothing whatever about physical error analysis all the while purporting physical analysis.

        Apparently, you’re in the same boat; also here.

        Snark all you like, Nick. You’ve consistently lost the argument where the rubber actually meets the road.

    • Nick, can it really be true that you both know nothing at all about propagated uncertainty and are impervious to figuring it out?

      Very hard to believe. And yet, evidence of its absence is right there before us. But, I admit, imperviousness is a non-unique solution to the problem of non-presence. Maybe there’s a different causal reason.

        Maybe there’s a different causal reason.

        Nick appears to be heavily invested in CFD modelling. Hence his appreciation for the GCMs. Nick, for your benefit, models are always wrong but sometimes useful and for the purposes you (probably) use them, they’re definitely useful. Instantaneous uses like modelling a wing’s performance or near instantaneous uses like weather forecasting. Fine.

        However, for the purposes of 100 year projections, GCMs are not useful.

    • Nick, in spite of a constant increase of anthropogenic co2 increase if you look at the yearly increase in temperature and co2 ppm per year, co2 clearly follows temperature. All your chart produces is that there has been a very slight underlying warming trend and co2 follows. It is not certain that all of the resulting increase in co2 is anthropogenic . While it is to be expected that anthropogenic co2 is mixed with the natural, there is no way of knowing whether the total amount increase is a result of human input or entirely from natural sources based on increases in temperature. Referring to isotopic amounts has run into considerable doubt. Also, the assertion that co2 remains in the atmosphere for hundreds of years is also false. At the current rate of sinking, 100% of the co2 in the atmosphere would be reduced to 0 if, in fact the co2 were in balance and anthropogenic co2 was the only cause in increase, in less than 100 years and all anthropogenic co2 were stopped immediately. … and in the last year NOAA has both adjusted both the co2 record and temperature after it pointed out that co2 followed temperature. They have also done some other things to try to account for what can only be massive of amounts of anthropogenic co2 that remains unaccounted for. The co2 record itself is no longer an apples to apples comparison. In a previous argument with Isvalgaard, I didn’t answer his last statement on TSI. However, he knows as well I do that small difference in numbers have big results. The entire notion of SLR is predicated on warming of the oceans. It doesn’t take much to get the catastrophic rise that has been predicted. If that had in fact happened, no one here would be arguing except how to fix this problem. The heat is definitely not hiding in the ocean.
      C/AGW has too many assumptions, and in any case it’s the best case scenario calculated for disaster based on those assumptions. Every single calculation was rounded up in favor of AGW, and every single mitigating factor was negatively reviewed and rounded down.
      TSI is an assumption of variability over time, all of the amounts of where that energy goes is also an assumption. A difference in any direction causes entirely different results. My point about the instrumentation error and the math, from the decline, should mathematically put us in the beginnings of an ice age, per the math, not the actual. Yet, those numbers when produced back in 2001 match all of the other calculations. There is absolutely no way that could have happened unless it was contrived.
      Unless you have a vested interest in AGW or just totally dense, this has to make sense to you. Arguing otherwise puts you in one of the two camps. Perhaps both.

      • If ‘co2 clearly follows temperature’, why did temperature lag behind co2 in UAH/RSS from 1998 – 2014 while that same co2 steadily rose over the period? How could co2 be rising but not temperature if co2 only follows temp? Co2 didn’t follow temperature then.

      • Co2 follows temperature the ppm per year clearly follow the temperature. Temperature did decline but there is an underlying warming trend. A slight one. Before NOAA started fixing the record, 1998 co2 ppm was 2.93 and temperature was 0.64 above normal for that year. 1999 temp was 0.46 above norm and co2 ppm declined to 0.93 . I graphed out every year from 1960 and every year co2 did the same thing, it followed. In spite of constant year over year increases. My point is that it’s somewhat warmer, and there is more co2. Whether it’s entirely from natural or anthropogenic sources, or some percentage is unknown. Only that co2 can not be causing deviations in temperature.
        I am stating this outright, I’m using their data. Whether it’s right or not, is another issue. Even though NOAA has been adjusting the data, the pattern is still evident.
        1994 1.91ppm 0.33c
        1995 1.99ppm 0.45c
        1996 1.25ppm 0.32c
        1997 1.91ppm 0.52c
        1998 2.93ppm 0.64c
        1999 0.93ppm 0.46c

        The trend lines and the slopes are the same. Co2 follows temperature. That’s not true for the years I presented, it’s true for as far back as I cared to go, 1960. There are people that can show co2 lags temperature in the past. The graph C/AGW has that shows total co2 amounts and yearly temperature anomolies is misleading. I’m saying co2 amounts are increasing because of temperature not because of anthropogenic co2. There would be no reason over a 5, 10, or 20 year period that co2 ppm would fluctuate with temperature in the face of constant year over year increases in production. It’s not as they have suggested a random variation. It is constant. The picture becomes even clearer when factoring in the size of the ever growing sinks, of which there is no possible explanation. According to C/AGW, the oceans were colder in 1960 than today, able to absorb more or less co2 ? And tropical forests, more or less in 1960 than today ? What reason could there be for today 1 and a half times more co2 is being sunk than the entire yearly amount than in 1965 ? And that’s the offical amount. The actual is probably much greater. The offical amount is 50%, I have anywhere from 68% to over 80%. You can do that too, mole amounts or weight per volume.

      • UAH/RSS both show a temperature decline in the LT from 1998-2014. Your meanderings still don’t explain why there was an almost 10% increase in atmospheric co2 during that same period while the temperature declined. According to your post “co2 clearly follows warming” and “co2 ppm clearly follow warming”, except obviously not.

      • Obviously you’re not looking at the same information in the same way. Did you graph it ? It becomes very apparent. Each and every year co2 followed temperature. According to the all, there has been no decline in temperature. Your ramblings seem to be a feeble attempt at discrediting this line of research in hopes that, ” the only thing left for temperature increase is co2 “. Do you think this hasn’t been done before ? And further, you tone isn’t one of interest, it’s condemnation which might lead to a pissing match of some sort, which I’m really not interested in.

      • LOL – so you claim that from 1998 – 2104 UAH/RSS lower troposphere temps rose equal to the almost 10% increase in atmospheric co2? Woodfortrees would even laugh at the odd postulation. You’re right tho, its not worth further deliberations about such a complete falsehood.

      • Calling it a falsehood and being one are two different things. The data speaks for itself, or did. From 1960 until 2015 co2 followed temperature. There is a third party involved and that is the interplay of cosmic rays. It is or was event in the record with the solar cycle and Ray activity in 1962 and 63. Belittling me won’t change those facts.
        Do you know what this site is ? It’s a site where true believers become skeptics. Every year the educational system churns out another batch of I’ll informed, spoon feed useful idiots. And every year the tactics, 15 year old information, and arrogance with a different name appears. Some quickly see what wrong, and others take awhile. There are many here, that were once believers that have converted over. Do you know how many skeptics become believers in AGW ? If you could convince me, you could convince every skeptic here. The science is not with you on this. That’s why no one goes back to believing in AGW.
        And I can and will defend my position that there has been an underlying warming trend and that warming trend along with cosmic ray activity influences co2 levels. There may be countervailing influences that I’m not aware of, but until so stated this stands.
        Which by the way, there are a lot of ideas here to which have a great deal of merit. This is just one of many. How it all fits together is why we keep talking about. Among skeptics, the science is not settled.

      • UAH & RSS data from 1998 – 2014 easily disprove your ‘co2 clearly follows warming’ claim. And global atmospheric co2 rose steadily from 1945 thru 1975 yet there was no appreciable global warming then, so you don’t seem to have any sturdy data on that 1960 – 2015 time span either. So that also disproves the falsehood you claim of ‘co2 following’.

      • uhh, no thanks, not interested in any more of your gobbledygook. You still can’t explain UAH/RSS 1998-2014 or 1960-75 non warming, no sense going any further. I’m guessing 4chan and Alex Jones are your ‘go to’ sources for cosmic rays. Take care now.

      • And you can’t explain the sinks either. All I have to do is see whether anyone at NOAA is listening. Evidently they are, else they wouldn’t have bothered to change the numbers. I don’t pay much attention to the numbers your throwing around, I don’t trust them. Either you’re a die hard warmest with a vested interest or dumber than a box of rocks.
        To you it’s rambling about nothing, to someone else it’s serious. I don’t think you have a clue what I’m talking about. It’s the co2 sinks. It seems you can’t do more than one equation in you head. Not only are the sinks a problem… you know suppose the sinks didn’t grow at all. And then there is the missing co2, production minus the 50 % that is suppose to have been sunk. Then that leaves, let’s cherry pick 2011, 7.5 BMT that’s unaccounted for, on top on the sink taking out a total of 19 BMT, suppose the natural sink is static at 6BMT as it was in 1965, then when you are looking at the co2 ppm with temperature … but then you have no idea what I’m talking about.

  31. I’m prepared to believe that Hanson really does believe in global warming. I believe this because he was one of the few to recommend nuclear as the best means of fighting it.

    Most of the other big supporters seemed more interested in promoting a social agenda, and one of the things they could not stand was Nuclear. It had to be their version of renewable or the highway.

    • You know, if the Greens/Alarmists *really* wanted to do anything to save the planet from a runaway greenhouse, then the solution to their problem is to wholeheartedly support powering the world economies with nuclear power.

      Nuclear power will satisfy the Greens/alarmists’ desire to lower CO2 emmissions, and the skeptic side will support nuclear power because it is one of the best alternatives.

      If the Greens/Alarmists can get over their revulsion to nuclear power, we can all get on the same page.

      This will never happen with wind and solar. Wind and solar are deadends and the sooner people realize it, the sooner we can start doing something that will actually make our lives better.

      • Problem is the propagators of environazisism don’t care about “saving” the “environment”, all they care about is controlling people, punishing people, subjugating people. They simply use their hordes of delusional followers who DO actually care about enviromentalism to push their socialistic political ideology.

  32. ..The “Trump Effect” is getting Yuuuge !!….Finally, sanity may be returning to this area of science…As for Hansen, he has lost all credibility…

  33. I should note the request to make a “tax deductible donation to the nonprofit Climate Science Legal Defense Fund. “

    • With the new administration in place, those guys will likely need a huge “Climate Science Legal Defense Fund”. Mark Steyn’s countersuit isn’t going to be the only legal tangle they get in – I’m wondering if there are any emails left on the EPA servers. I’m guessing that a lot of EPA folks wind up on disability from carpal tunnel syndrome – too many hits on the “delete” button.

    • I should note the request to make a “tax deductible donation to the nonprofit Climate Science Legal Defense Fund. “

      I got audited by the IRS 3 times under Obama, and many Tea Party Groups were harassed, and this group gets tax exempt status? Trump definitely needs to look into IRS treatment equity.

      • It would be interesting for you to make a claim to the Climate Fund. Since you are probably not a member of the 97% consensus that WU refers to that has been injured, you probably would not be covered. Tyranny of the minority?

    Like Australia ,that is no longer buying the science is settled crap , the so called USA climate scientists who can’t defend their pronouncements are going to see their funding vanish and their reputations exposed to direct sun light .

    • James Hansen Lecturing on Climate to Millenials

      (youtube)

      (Charlie Brown is Hansen’s agent…. only because he thought Hansen was his dad’s boss….. (Hansen, a close relative of Lucy the football sc@mmer, lied to him, shock!)).

  35. Let’s all remember Hansen is the godfather of catastrophic global warming.

    At the beginning, there was Hansen and Manabe. Manabe thought doubled CO2 might provide up to 2.0C of warming. But Hansen was the 4.5C guy, and somehow, he got Manabe banned out of the movement in the early 1980s. I mean Manabe was completely shut out afterward.

    And then when Hansen teamed up with Michael Mann and saw that screwing around the data provided big benefits for funding and reputation after Michael Mann’s 1998 hockey stick, he realized that they could get away with playing with the data and exaggeration was the way to go.

    Since then, it has been nothing but finding ways to make a tiny warming trend turn into a big warming trend and using dirty, dirty tricks to keep the pressure on and the funding flowing in.

    He was the godfather and he should pay a very big price for what he has down.

    • “Unfortunately?”

      I was wondering about that, too.

      I guess he means it is unfortunate for him in his effort to prove his case, because it will take a long time before it becomes apparent that CAGW is true.

      That also helps with his claims being disproved because it will supposedly take so long to show up because of the timescales involved. I can hear him now: “Just be patient, it’s coming. You’ll see that CAGW one of these days.”

      He is trying to cover all his bases.

  36. This is the problem. Temperatures increased from 56.3°F in 1910 to 57.4°F in 1945. CO2 increased from 300 to 310, for an increase in W/M^2 of 0.157W/M^2. In other words, trapping 0.157W/M^2 resulted in an increase of 1.1°F. Temperatures then increased an equal amount between 1977 and 2005. CO2 increased from 330 to 380. This resulted in an increase in W/M^2 of 0.66. 0.66 is 4.2x the energy of 0.157. How does “trapping” 4.22x more energy result in an equal increase in temperature? Clearly, there is a problem pointing a finger at CO2.

    • I have two questions about this graph set: 1) What global temperature dataset was used, and what version of it was used? (Or when was that version current?)

      2) What is the justification for stopping at 2006? I suspect the reason is that the hiatus started in 2001-2005 depending on which one of reasonably honest analysis methods and 1997-1998 according to what I consider as less-honest ones abusing the greatest El Nino after 1878 (according to most sources including https://wattsupwiththat.com/2015/11/17/is-the-current-el-nino-stronger-than-the-one-in-199798/), and the hiatus gradually got too great to ignore around 2009-2014.

        2) What is the justification for stopping at 2006?

        I just googled CO2 and Temperature Data and Graph and that chart came up. Choose any dataset or chart you want, they will all show the same response. Facts are the Δ°C/ΔW/M^2 for any ΔCO2. Simply open up MODTRAN and do the calculations. CO2 is irrelevant once H20 is thrown into the mix. Once again, the above analysis should have been the starting point of any serious scientific theory, and CO2 fails miserably using the data and charts the global warming alarmists have published. They don’t even know how to analyze and reach the proper conclusion of their data.

    • “This is the problem. Temperatures increased from 56.3°F in 1910 to 57.4°F in 1945. CO2 increased from 300 to 310, for an increase in W/M^2 of 0.157W/M^2. In other words, trapping 0.157W/M^2 resulted in an increase of 1.1°F”

      Nope.
      That’s not a problem.
      The +ve forcing of GHG’s did not counter the -ve forcing of aerosols until the 1970’s ….

      Global dimming ….
      https://en.m.wikipedia.org/wiki/Global_dimming

      And natural variation drove GSMT’s…..

      So, as ever there are natural climate cycles, that are ocean driven, and, as ever, some here think you can extrapolate with one or the other but not both.
      Both act together.
      Which is why CO2 forcing is never NOT going to involve slow downs/speed-ups.
      It’s actually quite simple if you just apply common sense, science really isn’t needed.
      GSMT’s couldn’t accelerate away until CO2 became the dominant forcing, which it did by the 1980’s.

      • CO2 became the dominant forcing, which it did by the 1980’s.

        1) Temperatures didn’t accelerate post-1980, the slope is the same as between 1910 and 1945
        2) CO2 only increased from 340 (290.042W/m2) to 400(289.288W/m2). Less than 1W/M^2.
        3) Water vapor has increased over that time
        4) Cleaner air/less particulate matter has allowed more radiation to reach the earth surface and most importantly oceans.

        Bottom line, cleaner air, moister air and El Ninos/Ninas can explain the temperatures far greater than CO2. Temperatures simply don’t match CO2. They follow ocean temperatures which are due to visible radiation, not IR between 13 to 18µ

      • Aerosols were so accurately measured prior to the 1980s and provide a definitive argument for unexplained temp variations in the past. Lol. Pretty graph though.

      • One thing we do measure well is humidity. Guess what? Since 1974 it has increased from 10 to 10.75, a 7.5% increase in the most significant GHG. Plug that into MODTRAN and you get a change in absorption of 289.288 W/m2 to 287.718 W/m2 for a Δ of 1.57W/M^2. That is the equivalent of changing CO2 from 400 to 560. Bottom line, cleaner air, greater radiation reaching the oceans, warming oceans, more humidity can easily explain the warming. You don’t need CO2, all you need is the Clean Air Act.

  37. I guess Tom Steyer and George Soros can sick their climate Gestapo on Hansen like they did to Roger Pielke, Jr. They got to much money riding on the hustle to let Hansen keep saying that.

    On the other hand, I’m not surprised. Jim Hansen can read a calendar and thus realize there will be a Republican President in the WH until at least Jan 20, 2021. So the point of no-return must politically be extended beyond that date to keep the perpetual hustle running.

  38. Old wine but sweet to the taste

    OLD DEATH TRAIN HANSEN
    Always Good For A Laugh

    More holy than thou
    He warns you of Venus
    The only thing now
    That hardens his penis

    He rants at the crowds
    A coot with the hypers
    His mind in the clouds
    A load in his diapers.

    He quotes from the Greens —
    We work for the many
    (But really that means
    They’re after the money)

    He quotes from the Reds —
    Consensus is dictum
    (Good socialist heads
    Are all up one rectum)

    A Fascist he cries
    This Goebbels of weather —
    The truth is in lies
    The bigger the better

    So just like a skunk
    His sight is alarming
    His science is junk
    There’s no global warming

    Eugene WR Gallun

  39. Rather than dialing it back, James Hansen should simply turn it off. That would be the scientific (and sensible) thing to do.

  40. “…we must get the political processes moving now.”

    Hansen is still demanding an immediate political solution. That’s not a big change from what he’s demanded in the past. However, I think he’s come to realize that telling people “we’ve waited too long and now it’s too late to save the planet” tends to make them give up. If it’s already too late to stop climate change, why even try? Climate change is just the means to an end for Hansen. So now he’s saying, it’s not too late after all. We just have to get started immediately. Of course, if we continue to ignore him, he’ll repeat the same message next year, and the year after that, and the year after that…

  41. The reality is that there in no real evidence that CO2 has any effect on climate. There is not such evidence in the paleoclimate record. There is evidence that warmer temperatures cause the amount of CO2 in the atmosphere to increase and that is because warmer oceans cannot hold as much CO2 as colder oceans. There is no real evidence that the increase in CO2 ever added to the warming. After more than two decades of effort the IPCC has made no progress toward determing what the climate sensivity of CO2 really is. They have been unable to measure it. Others have come up with scientific rational to support the idea that the climate sensivity of CO2 is really some small number cllose to zero if not zero but the IPCC has intentionally ignored this rational for fear of losing their funding. If CO2 really affected climate one would expect that the increase in CO2 over the past 30 years would have caused at least a measureable increase in the dry lapse rate in the troposphere but such has not happened. The heat capacity of the atomosphere and gravity cause the surface of the Earth to be 33 degrees C warmer than it would be without an atmosphere. This convective greenhouse effect, as derived from first principals is responsible for all 33 degrees C that has been observed and it has nothing to do with the LWIR absorption properties of so called greenhouse gases. There is no room for an additional radiant greenhouse effect. A radiant greenhouse effect has not been detected anywhere in the solar system including Earth and Venus. Without the existance of a radiant greenhouse effect the AGW conjecture is nothing but unsupported science fiction.

    The primary greenhouse gas in the atmosphere it H2O, not CO2. Removing all the CO2 that has been generated by Man’s burning of fossil fuel would have little effect upon the total amount of greenhouse gas in our atmosphere. Molecuel per molecuel, H2O is a much stronger absorber of IR than CO2 but all good IR absorbers are also good IR radiators so it is very doubtful weather the so called greenhouse gases provide any insulation what so ever. There are no engineering applications where CO2 has been used as an insulator. We must also take note that the primary means of heat energy transport in the troposphere is by conduction, convection, and H2O phase change. Heat energy via LWIR absorption band radiation is insignificant and has no effect upon the lapse rate.

    Dr Hansen needs to realize that his predictions haave been wrong because his models have been wrong.

    • Will,
      Hansen abandoned his veil of science methodology when he retired from NASA to become a full-time climate change advocate.

      Retired Hansen no longer needs to be a scientist. That is someone carefully weighing projections against huge uncertainties. For Activist Hansn, it’s full-on projection, damn any uncertainty.

  42. Does this mean J.Mann and J. Han are going to accept emails from citizens who actually witness “climate” change? Oh! Of course not! Only the chosen of god are allowed to have opinions.

  43. Climate change can be controlled as easy as controlling a home a/c system you just need to know where the controls are located. And be able to pay the price requested.

  44. So after 20 years of “we MUST act before [pre-2017] or it will be TOO LATE!”, we’ll now get “we MUST act before [next date for moving the goalposts] or it will be TOO LATE!”.

    That about it?

    • I think Hansen is just trying to extend the time before he is held accountable. He is moving the goal posts farther into the future. It’s not quite a “never mind”, it’s more like an “I changed my mind”.

  45. The Christmas gifts are just pouring in!

    Greed Party, I mean Green Party, shill, I mean Jill, has just cancelled recounting in PA because a judge asked her to simply post a 1$ million bond. I don’t understand why she wouldn’t comply, seeing how she raised many times the amount necessary to recount the states she targeted. I mean, she now has around $7 million in the bank, so what’s the problem?

    Her goal was $2.5 million, then $4.5 million, then $7.5 million, and it’s now been raised to $9.5 million. Meanwhile, Hillary is begging for unpaid VOLUNTEERS to recount! I get the feeling there is going to be a lot of money left over in a few days. Time for a three week “party business conference” in Aruba, right?

  47. Using land only data to proof the globe has gone back to normal is not correct.

    http://woodfortrees.org/graph/rss-land/from:2010/plot/rss/from:2010

    As you can see all over the timescale, the land temp is just more “nervous”, jumping up and down more than global with its lage weight of oceans with more heat storage capacity.

    The differrence between max el Nino and now is 1.3°C for land only compared to global 0.6°C.

    Some have claimed, that the ocean heat capacity is delaying the temperature drop, Therefore land only graphs show the cooling a bit earlier. But in the grap you see no lag. Just the amplitude is higher.

    BTW, both curves went up a bit again…

  48. Back in my father’s days, schmucks like Hansen would have been locked in an asylum where they were protected from themselves.

    • ‘Asylum’ is just another word for ‘safe space’.

      Put them all in an asylum, that’s what they want anyway.

      • What if though? It would explain DT softening his stance (which he did recently). Wouldn’t it just be intriguing?

      • “What if though? It would explain DT softening his stance (which he did recently). Wouldn’t it just be intriguing?”

        Softening his stance? Have you been reading the New York Times, Simon?

        I suggest we just wait and see what Trump acutally does instead of speculating on what he will do on this issue. It shouldn’t be long before we know one way or another. And if you read the transcript of the New York Times interview, you wouldn’t think Trump had softened on anything to do with climate change. Or at least, I didn’t.

  49. Hey, if your crazy predictions reach their sell-by date you can either refine your ideas to match the world and it’s data or you can back the truck up and tow the goal posts ten more years down the road.
    Jimmy obviously prefers his carbon belching truck to, you know, science and thinking and stuff.

  50. Basically the “deniers” were 100% correct, aka Tony Heller, Steven Goddard, John Coleman and Co from the very start. Even the “lukewarmers” aka blackboard Julie are now backing off LOL

  51. Folks,

    Very entertaining/instructive/provocative info. THANKS.

    Questions…
    Does the ocean emit long wave IR, or just land?
    Or, what frequencies of IR (if any) are emitted by the ocean that can be absorbed/re-emitted by CO2?
    Or, what is the general pathway for shortwave insolation-caused ocean-warming to result in long wave radiation to space.

    Thanks for whatever answers are given.

  52. Regarding the thick black curve in figure 1: It looks like it was smoothed by a time period much shorter than 5 years, maybe around 1-2 years. Also, what is the justification of having the observation period ending 5 years ago in comparison to a 1988 forecast? Above the graph is a heading, “Models versus observations 1958 – 2011”.

    Another thing, the observed temperature dataset is not noted, let alone its version. I tried my hand at using Woodfortrees to duplicate this, and I got a close approximation by smoothing HadCRUT3 twice by averaging periods close to a year and using begin and end times, as such: http://woodfortrees.org/plot/hadcrut3gl/mean:12/from:1957.5/to:2012.2/mean:11

    Any comments please, such as what global dataset and what version thereof (or what time the version used was current) was used, and the specific smoothing algorhythm?

    At this point, I don’t think it was necessary to stop at 2011, because global temperature continued its shortfall from the model forecasts until the spike from the recent El Nino.

  53. Hansen’s intent is obvious. He and others spent the last several years stirring the left into a froth of panic over the climate. Now with Trump’s election, they are in total meltdown. The climate is done, there will be federal immigration agents kicking down doors and jailing people indiscriminately, and the Supreme Court was the only thing keeping Trump from re-instituting Prima Nocta using his pen and phone.

    Now that Hansen and his ilk have pushed so many to the edge of the irrational cliff, he wants to talk them back down so they fall back in ranks and will be ready for the next battle. The last thing they want is for people to break ranks and start accepting that they can’t force their agenda onto the world, so they will have to “wait and see” what the climate does next. That’s game over for the hysterics pushing the global warming scam.

  54. Hansen quote:

    “Stopping human-made climate change is inherently difficult, because of the nature of the climate system: it is massive, so it responds only slowly to forcings; and, unfortunately, the feedbacks in the climate system are predominately amplifying on time scales of decades-centuries.”

    If this is true, and I personally think that it is, then how is it possible for scientists to have already reliably quantified the degree to which this massive, slow-reacting climate system responds to our forcings, faster than the climate system has had a chance to actually respond to them?

  55. Anthony I disagree with your conclusion. I don’t think he had a change of heart or suddenly thinks that climate sensitivity is lower. I think it’s much simpler and more obvious than that: if he continues to claim we’re doomed and past the point of no return (actually past the tipping point) then there would be little justification for reducing emissions as it would be too late. Therefore he must reframe his argument to convince people and governments that there is still a need to reduce emissions and still time to save the planet.

    It’s that simple. Either it’s too late and the ballyhooed tipping point has been exceeded or it’s not. If it’s too late then any investment should be made adapting to future warming not trying to prevent it.

  56. The huge amount of discussion about whether Dr Hansen flouted either or bothDC laws or fashion rules overlooks a more significant point
    Given he has now argued we have decades
    to act on emissions or the amount of CO2 in the atmosphere this should be made clear to the msm and climate activists everywhere whst their guru now thinks
    No doubt he will cop further abuse from radicals like Naomi Klein as having “sold out”

    Second his now position seems to underpin
    the position of Bjorn Lomborg who has been arguing along similar lines for over a decade ie we should hasten slowly as there is no imminent emergency and we should invest in R and D to bring down the cost of renewables before rushing into them
    Now I am not defending Lomborg but am making the point even his essentially similar views that GHG are a problem for the climate are not close enough to the orthodoxy rampant in certain academic circles
    Accordingly Lomborg’s more cautious approach now remarkably similar to guru Hansen has resulted in him bring scorned and excluded from universities by the dominant orthodoxy that we must act now and radically so.These academic theories of climate crisis now dominate left of centre political parties policy positions
    Eg in my home state of Victoria Australia
    which has had for decades a reliable brown coal fired electricity system supporting locsl
    manufacturing the local greens have set a target of 90% renewables (read wind and solar) by 2030 which is only 14 years away while the centre left governing ALP seeks 40% renewables by 2025 in even less time.
    My guess is Hansen’s revisionary stance will be just ignored or hushed over by the climate activists and their supporting msm such as the Fairfax press and the Guardian

  57. Follow the money: he wants his side to not miss the surge in traditional energy stocks.

    He probably already got in before Trump made it to be president-elect. Al Gore too.
    These guys have no shame. It is and was all about the money.

  58. Hansen should be tarred & feathered & ridden out of many towns all over America on many asses & always facing aft. He’s a laughing stock & deserves such punishment until nature take its toll.

  59. Seems like the end of the gravy train loomed into sight and had the be pushed just over the horizon where it belongs, so more fear , uncertainty and doubt about the future can be sown among the populace

  60. Seems he’s realized that his dire predictions of imminent disaster are not going to happen, so he has to do what a lot of people do in that situation …. start a new dialogue and pretend they never made any of the dire predictions. That is a favorite tactic of most prophets of doom.

  61. HANSEN: Deer frozen in the headlights of approaching Trump Train.

    Complex political issues rendered into simple sentences.
    5 cents, please.

  62. I think it is simply that JImbo is getting older and wants to retire to Florida where he can live nice and warm. That would seem contradictory to his position to want to cool the planet for most of his entire grant seeking career.

  63. Crony climatism, fabricated temperature records and wild claims of catastrophic climate disaster have pushed CAGW and AGW past the tipping point of any shred of believability. Hansen’s slight moderation in tone is designed to postpone total destruction–and that’s all it “might” accomplish.

    • “Crony climatism, fabricated temperature records and wild claims of catastrophic climate disaster have pushed CAGW and AGW past the tipping point of any shred of believability. ”
      Beautifully stated …….

  64. Look at the graph presented above. It starts at 1975 but it could as well have started at 1945 because we all know that temperatures fell between 1945-1975. So the total temperature change for the 70 years from 1945-2015 is at most 0.3C. That’s it folks. 105 PPM of co2 pumped into the atmosphere. All tgis alarm alarm alarm over 0.3C.

    He says that the climate system has “momentum”. That there is heat built in. Where? Where is the evidence of that? There is none. If co2 is having some small effect on temperature it will require pumping in vastly more co2 to get any additional al increase. There is no “built in” momentum. There is no evidence of any momentum.

  65. Earth’s carbon cycle contains 46,713 Gt (E15 gr) +/- 850 Gt (+/- 1.8%) of stores and reservoirs with a couple hundred fluxes Gt/y (+/- ??) flowing among those reservoirs. Mankind’s gross contribution over 260 years was 555 Gt or 1.2%. (IPCC AR5 Fig 6.1) Mankind’s net contribution, 240 Gt or 0.53%, (dry labbed by IPCC to make the numbers work) to this bubbling, churning caldron of carbon/carbon dioxide is 4 Gt/y +/- 96%. (IPCC AR5 Table 6.1) Seems relatively trivial to me. IPCC et. al. says natural variations can’t explain the increase in CO2. With these tiny percentages and high levels of uncertainty how would anybody even know? BTW fossil fuel between 1750 and 2011 represented 0.34% of the biospheric carbon cycle.

  66. My friends,

    Back to topic, I’m afraid – Hansen.

    From the east side of the pond, what I see is this. When someone with any kind of political power contradicts what they previously said, it is incumbent on them to explain the reason why.

    Although I’ve lived in the US, I have no time for your political institutions (nor for any this side of the pond, neither). But didn’t Hansen testify X to congress back in 1988? If he’s now saying not-X, he has a duty to explain why. And if he fails to explain, is he not guilty of perjury? Not as serious a crime as it should be, in my opinion.

    And on another tack: I’m sorry, but in my estimation those of you who see Trump as some kind of divine deliverer are in for a big shock. That’s even if he is confirmed as president.

    • “And on another tack: I’m sorry, but in my estimation those of you who see Trump as some kind of divine deliverer are in for a big shock. That’s even if he is confirmed as president.”
      Somehow the liberals continue to drag Trump into every conversation, perhaps because they
      can’t come up with any plausible arguments. “That even if he’s confirmed as President.”
      This is pretty ignorant talk folks, even from a Brit. Amazing how an irrelevant candidate, fronting for Hillary and being financed by Hillary, can claim the need for a recount , and in states where illegal voting by illegal aliens was nowhere near the level achieved in corrupt California. She claims she just wants to make sure the election was honest, but avoids recounts in all those places where we KNOW the election was not honest and wants a recount that will allow those illegal immigrant votes to stand. Trump’s first order of business in legislation that will eliminate the Democrat Party’s bad habit of allowing the dead, unborn and illegal immigrants from casting ballots in Federal elections. It is long past due to bring honesty to the election booth. Many a Democratic President was elected thru fraud. Just take a look at LA and Cook County.

      • Oh my dear Arthur,

        Don’t you know about the electoral college? Don’t you know that individual “electors” can be bribed to vote differently from the popular vote inside their states? Don’t you know that there’s a possibility (remote, I admit) that the electoral college might declare H. Clinton president rather than D. Trump?

        I suspect I may know more about your country’s political system than you do.

        Cheers,
        Neil

  67. Actually, Hansen has shocked the corrupt green folks before when he insisted that renewable power like wind and solar was a stupid and ineffective way to reduce carbon emissions and strongly advised nuclear power, advice which the majority of greenies seem to continue opposing, irregardless of the immaculate safety record of nuclear power in the Western countries. But then, no one ever accused the greenie beenies of logical thought These nuclear-ignorant souls continue pointing to Chernobyl of decades ago, a reactor that would never have been allowed in any Western country, or the many advances in safety design and response capability that virtually guarantees that we will continue to experience zero fatalities as a result of operating our nuclear reactors. My big criticism of Hansen is his failure to push molten salt nuclear technology.

  68. “Stopping human-made climate change is inherently difficult, because of the nature of the climate system: it is massive, so it responds only slowly to forcings; and, unfortunately, the feedbacks in the climate system are predominately amplifying on time scales of decades-centuries.”
    Actually, I believe that it is easy to stop 97 percent of climate change in 2 steps.
    1. Quit altering the data.
    2. Quit lying about it.
    See. Done at no cost or taxes.

      I like your style, Gerald! Short and sweet, and to the point.

  69. Anyone that seriously seeks the truth, this chart can explain the warming of the lower atmosphere and cooling of the stratosphere. CO2 can’t do that. Bottom line, cleaner air allowed more radiation to reach the oceans, warmer oceans produced more humidity, more humidity traps more heat. Less humidity in the stratosphere trapped less heat. CO2 is a constant 400ppm up to 80km.

  70. CO2 is a constant 400ppm up to 80km. Temperature doesn’t follow CO2 in the atmosphere, it follows H20 and O3, not CO2.

  71. NASA never mentions CO2 when explaining the temperature gradient for the various atmospheric levels.

    Temperature in the Mesosphere
    The top of the mesosphere is the coldest part of the atmosphere. It can get down to -90° C (-130° F) there! As you go higher in the mesosphere, the air gets colder.

    The air is much thinner (less dense) in the mesosphere than in the stratosphere below. There are fewer air molecules to absorb incoming electromagnetic radiation from the Sun. That includes molecules of ozone, which absorb ultraviolet radiation and heat the stratosphere. In the mesosphere, the thin air and small amounts of ozone prevent the air from warming much.

    Carbon dioxide in the mesosphere also helps make this layer cold. CO2 molecules absorb heat energy when they bounce off of other molecules. The CO2 releases some of that energy as photons in a process called radiative emission. Some of those photons travel upward into space. This carries heat away from the mesosphere.

    Temperature in the Stratosphere
    The temperature gets warmer as you go upward in the stratosphere. Earth’s “sunscreen”, the ozone layer, is within the stratosphere. Ozone molecules absorb energy from ultraviolet “light” coming from the Sun. They turn that energy into heat. That is what heats the stratosphere.

    Temperature in the Troposphere
    The temperature gets colder as you go upward in the troposphere. Light from the Sun heats the ground. The warm ground gives off the heat as infrared “light”. The IR energy heats the troposphere. The lowest part of the troposphere is the warmest because it is closest to the ground, where the heat is coming from.

  72. When describing the temperature gradient of Antarctica they explain it due to H2O, not CO2.

    Water has a high specific heat capacity, this means that it has a large influence on local weather, cooling or warming the surrounding land and keeping temperatures more even and constant. If you look at the climate zones map at the top of this page, you will see that coastal areas generally have smaller temperature ranges over the year than inland areas. This is partly due to the high specific heat capacity of the surrounding or nearby water.

    The clear skies and dry air above the Plateau allow continuous long-wave heat loss from the surface, and even during the summer little heating occurs because of the high surface albedo. The resulting equilibrium temperature profile is very stable: this is consistent with a downward sensible heat flux, which compensates the net radiational loss at the surface. For example, measurements at Vostok on the Plateau in July 1989 showed – 78� C at the surface, – 44� C about 600 m above (i.e. an inversion of 34 K !), and then cooling to -73� C at about 8,000 m (1). The inversion elsewhere in Antarctica in winter ranges from about 25 K inland to about 10 K around the coast, but its strength varies from-day-to-day, especially along the coast, as weather systems move and evolve.

    Clouds are more common near the coast (in fact some coastal stations are overcast most of the time) and they are always stratiform (3).

    There are large variations in climate across the continent owing mainly to differences in latitude, altitude, and distance from the Southern Ocean. The Antarctic climate as a whole can be discussed in terms of three different climate areas: the interior climate, the coastal climate and the climate of the Antarctic Peninsula.

    The coldest and driest areas are inland, where the ice sheets form high plateaux (exceeding 4000m altitude on the East Antarctic Ice Sheet). In these areas, extremely cold air descends to create persistent high pressure that brings settled conditions with relatively low wind speeds. Temperatures during the austral summer rarely exceed -20°C and during the winter months temperatures are often around -60°C. Precipitation is usually snow in the form of ‘diamond dust’ – tiny ice crystals formed from the sublimation of water vapour in a clear, but intensely cold

    Funny how all these groups faily to mention CO2 of the cause of any temperature gradient.

  73. I have often wondered with the UN ranting nonstop about global warming and sea level rise, why they are spending billions of dollars in renovations on the UN headquarters which is only about 100 feet from the East River and only a few feet above sea level rather than moving to higher ground. You learn more from somebody’s actions than their words.

  74. Anthony Watts commentary: “I think Dr. Hansen has come to the conclusion that climate sensitivity is not as sensitive to carbon dioxide as it was once thought to be in his original”

    Anthony, I disagree and think that he is sucking you into a false sense of relief that he is giving up his assault on science. His new narrative is not an admission by this junk science zealot that he is wrong. Rather this new narrative is a ploy to avoid accountability for the failure by his models and to push the doomsday prediction out to a future date so his models failures can no longer be checked against reality. He is still waiving his hands and saying “the sky is falling”, but like the “heat is hiding in the ocean” ploy he now has a convenient excuse for why NY is not under water and the planet is not on fire. Now he can keep making his nonsense claims and demands for carbon taxes and just point and say to his cult followers that doomsday is “in the pipeline”.

  75. Translation: Oct. We must elect a Democrat or we are doomed.
    Dec. Don’t give up and stop supporting us, after Trump we still have time.

    Pathetic.

  76. Most Professions are governed by a Professional Body, usually with appropriately gleaned government remit as to establishing entrance requirements & licensing, professional standards of practice, disciplinary powers, Codes of Conduct, fiduciary duties to society at large, etc. Dentists, Doctors, Lawyers, Pharmacists, Architects, Engineers (I speak from experience — if I designed a dam which failed *I* would be on the hook as the Certifying Engineer) and a host of others, all subscribe to these principles in order to gain the acclamation of Certified Practitioner in their field of expertise.
    What, pray, is the Professional Body which governs the practice of “Climate Science”? Which jurisdictions give them charter to practise? From evidence to hand, I think the answer is a stunning “NONE!!” And so these so-called “Scientists”, untramelled by any code of Professional Ethics, have run-amok for 30 years or so, ON THE PUBLIC PURSE, with every fantasy-theory in their book (to serve their ends) WITHOUT ANY ACCREDITED PROFESSIONAL CENSURE.
    If *you* were to write the foundational Charter for the Professional Order of Snake-Oil Salesmen (many, many applicants!), you cdn’t do better than assess there’s no need ….. gullible governments, complicit with incendiary, sensationalist-seeking media ([wo]manned by otherwise no-hope flotsam-clutchers), and a (sadly) gullible public, 90% of whom suck this trash up as TRUTH.
    My proposition is an Institution of Professional Climate Scientists: maybe 2 Chapters, representing the divisions, but facilitating the ongoing dialog by institutional rules of cross-examination in an objectively-driven, formal process, not media-hype and scare-tactics.

  77. Whenever someone has the ignorance, audacity and naivete to tell you that we have five years to act, you can safely tell him to relax. After five years, we’ll be granted another extension. We are ALWAYS granted another extension.

    We will never hear, “Well, I guess we’d better change our strategic approach from mitigation against climate change to adjusting to the global climate cycle.”

  78. Forgotten is Claude Levi-Strauss’ greatest fear, “the poisoning of the planet,” our air quality; what were relatively uncontaminated oceans, weather systems and food chains, which is now expected no later than 2024 rather than the original of sometime after 2030.

    In 1972 that process of poisoning the planet was called “Overshoot and Collapse.” A more terrifying descriptor is “Global Famine,” which seems to exceed that of “the Sixth Mass Extinction Event” for some reason.

    Warming, climate change and the rest, are attributed to only one, or a few, of the 90,000 manmade chemicals floating about in our spaceship’s biosphere, our lungs, livers, lymph nodes and future life forms.

    Effective detoxification of our spaceship’s various living environments – is that possible? Before the life forms upon which we’ll depend upon for our subsistence get over warmed and cease to be?

  79. Create the “In Limbo impending doom” that is ALWAYS impending, so that in 100 years from now, we’ll have the same rinse and repeat, with the proviso that there is permanently a “little more time”

    I love the paradox, incidentally

  80. The global warming train’s steam temperature increased of 0.2°K in a decade. At this rate, the global warming train will reach the Andromeda galaxy in 4 billion years (anyway)

  81. It’s just occurred to me that Hansen’s recent statement that mitigation is not immediately urgent, but can be phased in over a lengthy period, is consistent with the implementation of a “nuclear” CO2-reduction strategy. I suspect he made this statement after consulting with a member of Trump’s team, which may be planning to unveil such a plan.

    Hansen is Gore’s advisor on climate-related matters. Gore’s visit to Trump is consistent with what I speculated about Hansen, namely that a “nuclear” CO2-reduction strategy is in the works.
