Whacky Peter Wadhams Doubles Down on the Sea Ice “Crisis”


Guest essay by Eric Worrall

In the wake of his failed 2016 “ice free” prediction, Dr. Peter Wadhams has spoken up, claiming most scientists are frightened to speak up about the climate crisis – though he admits his confidence in predicting exact dates has taken a dive.

Dahr Jamail | Arctic Expert on Sea Ice: We Could “Reach Zero” Within Two Years

Arctic sea ice is in big trouble.

This is bad news for multiple reasons, the primary one being that Arctic sea ice helps keep the polar regions cool along with working to moderate the entire global climate.

“Sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space,” explains the National Snow and Ice Data Center’s website. “As sea ice melts in the summer, it exposes the dark ocean surface. Instead of reflecting 80 percent of the sunlight, the ocean absorbs 90 percent of the sunlight. The oceans heat up, and Arctic temperatures rise further.”

Truthout: Numerous people have predicted the vanishing of the Arctic sea ice in summer, including a US Navy study that predicted it by this summer, but they’ve all been too early in their predictions. Why do you feel confident about predicting that summer Arctic sea ice will disappear in either 2017 or 2018 at the latest?

Dr. Peter Wadhams: I don’t feel confident — it’s simply that this is the trend shown by the sea ice volume in recent years, and since that volume is now quite small, it ought to reach zero within one to two more years. But, of course, something could happen to change that.

We have reported quite extensively on the threat of increasing amounts of methane being released as permafrost melts. Why should people be concerned about methane releases in the Arctic, and the fact that these are increasing?

We have modeled what would happen if the rate of emission increased radically to be equivalent to a 50-gigaton pulse (predicted by the Russian scientists who work on offshore methane). It would give a 0.6C boost to global warming immediately — which is a very large figure.

You have been outspoken and frank about how rapidly the situation is changing in the Arctic. Why do you suppose more scientists aren’t being as outspoken in their alarm and concern over what is happening there and what it means to the planet?

Career considerations: If they speak out, they fear that it will upset their promotion prospects, so they keep their heads down.

Any final thoughts you’d like to leave with our readers?

As a final point, sea ice retreat from the Greenland Sea has prevented the formation of chimneys — deep cylinders through which surface water sinks to great depths. This slows the thermohaline circulation [the movement of seawater in a pattern of flow dependent on variations in temperature, which give rise to changes in salt content and hence in density], which will result in cooling — or slower warming — of the Northwestern Atlantic coastline (e.g. Britain) and faster warming of the tropical Atlantic (e.g. more intense hurricanes).

If I’ve understood correctly, we can now expect sea ice to melt away in 2 years (maybe), an imminent 0.6c spike from methane, and a potentially severe drop in Northern temperatures thanks to interruption of the Thermohaline circulation, the “Day after Tomorrow” scenario.

Settled science, anyone?

  1. Do you know why you were wrong? If not, then why do you think you are right now?
    That is called science.
    You are something by a different name.

    • “No thanks, I haven’t had enough beer yet and could not stand any more of these wacky Peter Wadham ravings while sober.”

  2. Scientists are afraid to speak up on the issue. That much is true. But the reason has more to do with likely loss of funding and perhaps jobs if they tell the truth about the fact that this panic is unsupportable on the basis of the data.

    • Exactly! Can he show a single instance where anyone was disciplined or disadvantaged by making excessive or even nonsense claims about the hazards or consequences of projected climate change? What a hack!

      • He is correct. If you speak out by making ridiculous, ill-founded predictions that will be validated / disproved before the end of your career, it is likely to impact your reputation.

        Even alarmist scientist are running a mile from Wadham’s unscientific nonsense and calling it “bollocks”.

        On the contrary, if anyone made a mid term project that works, they would earn respect.

        Since no one has sufficient understanding to predict even a few years ahead most just make hand waving claims for periods so far away that they will be in a rocking chair or a wooden box before they ever get tested.

      • Sorry about the double post, I’ve been getting messages about server updates when I try to post all morning.

    • Or likely the reason they fear speaking up is that too many sceptics keep poking big huge holes in whatever they have to say. It’s one thing to speak without interruption or criticism, it’s entirely different looking down the barrel of eminently qualified sceptics rebuttals.

  3. Wadhams should at least entertain the possibility he was wrong all along. He seems to have a history of persistence in making bad predictions.

      • That is the way of a religion when its prophecies fail. Scientists love to see predictions fail because then they have learned something. Religious loons only go back to their book of religious teaching and make the same old prophecy but just give it a new date. Miller in the 1850s was the classic recently, but he was hardly unique. Seems the rapture is a bit delayed, we just have to interpret the Bible some more.

        As for these arctic ice loons, have they truly never heard of enthalpy? The buoy data shows a decrease in ocean enthalpy in the arctic with the rollover of the AMO. Ice cover itself can be a function of a lot of other things on a yearly or so basis, but in the long run, when you lose enthalpy, you eventually freeze up.

      • Yeah, ShrNfr, temperature is a lousy measure of heat balance. It’s like trying to tell whether a city’s population is rising or falling by counting cars on the beltway.

      • Most “the end of the world is nigh” claims get recalibrated every time the world fails to end. They never realise they were wrong about the world ending, they just miscalculated the date.

        Niburu is still lurking just out of sight ….

      • Aren’t there Biblical passages which state rather plainly that no one “knows the day or the hour” of the Second Coming of Christ (save God, of course), and that it will come like “a thief in the night”, completely unexpected?

        Doesn’t stop your average cult leader from trying, I guess.

      • I once talked with a gentleman who when I mentioned that verse to him replied; The Bible says you won’t know the hour or the day, but it says nothing about the month or the week.

        Literalists drive me crazy.

    • It seems almost as if Wadhams is suffering from a kind of gambler’s fallacy – “Surely this time when I make my prediction, it will come out the way I say.”

  4. ” But, of course, something could happen to change that.” ??

    So he admits they actually have no idea about what direction our climate will take in the next 5 or 10 years ! ! Settled Science….?? Obviously not !

    • All he is doing with that comment is preying for a major volcano so he can say : ” well of course it would have disappeared, except for this unforeseen event which changes everything”.

      The “something could happen” has already happened, the rate of melting has reduced since 2007, the date of minimum is drifting earlier, the accelerating melting on which all the dramatic claims were based is no longer accelerating, it is slowing.

      Only looney-tunes likes Wadhams keep banging on as though post 2007 data tells us nothing new.

      • As he girded himself against the noxious, sulfurous fumes that belched from the chasm in preparation for descent into the bowels of the mountain where mighty pressure and unimaginable heat made rock run in syrupy rivers, Bob paused to consider the unlikely series of events that had led him to become the Great God Vulcan’s proctologist. — Stan Hunter Kranc, State College, PA

  5. Less sea ice means that more heat escapes from the oceans, and therefore into outer space, ie global cooling.

    Wadhams confuses minimum ice extent in September, with “summer”. By Sep, very little solar energy is entering Arctic seas.

    This process is actually a very good example of how the Earth is perfectly able of regulating its temperature.
    After all, it has gone through many episodes, even in recent millenium, when the Arctic was much warmer than now. There was no “runaway warming” then, and there won’t be now.

    • Re: “Wadhams confuses minimum ice extent in September, with “summer” – until Sep 21st, it is summer.

      • OK, then by that definition autumn begins with a six-month polar night at the North Pole. Not much albedo related warming expected there then, but the open sea in polar night surely dissipates a lot of energy.

    • Exactly.

      What is important is the amount of ice between May and July. Say about 6 weeks either side of the summer solstice.

      This coincides with when daylight hours are the longest and the angle of incidence is highest as opposed to the scenario when the sun simply grazes the surface and is largely reflected irrespective of ice conditions.

  6. Yes “something could happen to change that ” . Yes like another goofy prediction from Wadham in about 2 years time .
    Does guy teach people science ?

  7. It is great to see this because TUCRADIO had his talk from Milano, Italy on this morning and it was full of so many references to ‘models’ and how the Arctic will soon be free of ice in the Summer. In the lecture he did sprinkle how the global temperature hasn’t risen for 10 years. Hello! What about 18? or maybe more! Anyway: kudos.

  8. I have been listening to these “boy cries wolf” predictions for years and years now. They are always wrong.

    But let us play devil’s advocate for a moment. If all the ice at the north pole melted one summer, so what? What would that do? Would it be the first time in billions of years? Would the Russians sneak over the poles and attack us by coming down the middle of Canada? Would we not have ice for ice cream in the deep summertime? What?

    What would be so darned bad about an ice free north pole in the summertime?

      • @ JohnKnight, That makes me wonder if the Russians have an “in” they are building bigger and stronger Icebreakers as we speak. (And even “renting” them out to cruise lines).

      • Well, the German icebreaker, the Polarstern, is up there now at 87°N mashing up the ice just to make sure it doesn’t stick together to firmly.

        Join the calls for a 10 year moratorium on icebreakers in the Arctic north of 82°N under any circumstances.

    • But think of all those cuddly polar bears. They might get wet with no ice floes to sit on while they wait for seals to jump to be eaten.

      • Latitude October 9, 2016 at 4:49 pm
        “I’m with Mark on this one……I can’t figure out why I should care”

        Why care,, why you should care? Because there are vast amounts of minerals, Oil and gas deposits in the arctic and if the ice melted anyone, I mean just anyone could go and mine it or pump it out… it ,,it would upset the balance of nature, mankind in its rightful place as prey rather then the the alpha predator, totally against the intent of Gaia (Gaea) it must be stopped,,

        Do I need a tag?
        Hmm, or for Dr. Peter Wadhams; “Here’s your sign”


    • And it would likely be ice free for only a few weeks. And, of course, by ice free we mean less than 1 million sq. km. It will be interesting to watch the sea ice and the NH temperatures (as well as global) over the next 10-30 years to see what happens if and when the AMO starts going negative and especially if the PDO goes partially into phase with the AMO.

      • BillW_1984
        And it would likely be ice free for only a few weeks. And, of course, by ice free we mean less than 1 million sq. km.

        Now, recognize that even “1 million square kilometers of “ice free” Arctic Ocean” actually represents the ENTIRE region between 90 north and 85 degrees north latitude. (Figuring a curved cap centered on the north pole of area 1.0 Mkm^2.)
        In fact, you need 9.0 Mkm^2 sea ice to even get past 75 degrees north latiude.

        Area (Mkm^2)	Latitude
        1.0	84.9
        2.0	82.8
        2.2	82.5
        3.0	81.2
        4.0	79.8
        5.0	78.6
        6.0	77.5
        7.0	76.5
        8.0	75.6
        9.0	74.7
  9. I think specifying a specific year when the ice caps would disappear was always a stupid idea. I am sure it was an attempt to show how serious the problem was. Even so, if the cap was getting smaller every year they could at least claim climate warming was on-going. but when it starts to grow larger, that would seem totally contrary to all their predictions. How do you explain that? I would think from this point on any evidence suggesting the earth is cooling off would become a death nail in their claim. Their projections did not leave any room for delays or reversals.

    • Yes, but we really need to see Arctic ice area increase over the next 5 to 20 years to make good that point.

      Presently, the data set is too short to enable any firm conclusions to be drawn.

    • Yes, I wonder if they will just keep claiming that the warming is causing cooling via polar vortex “weirding” and slowing the thermohaline circulation, and witches? Or will they just go back to the old version where coal and aerosols and pollution are causing the planet to cool, possibly into an ice age, (oh wait, no one ever said that – will be pretty funny if they try to bring that back and will have to go re-edit the Wiki pages) and we have to get rid of all fossil fuels due to global cooling. Sadly, I predict the MSM would mostly just go along with it, we would now have global cooling “de-niers”, one major and several minor political parties invoking CAGC and they can go through another 30 year half-cycle, this time with cooling alarmism.

      I am an experimentalist myself, so I will keep watching the evidence. I don’t know if it will cool slightly or keep warming a bit. I do think that, at least so far, it looks as though the more drastic predictions of warming don’t seem to be materializing. And I think the next 30 years will be quite enlightening, one way or another. After all, you need to go through a complete cycle with modern satellites and measurements to really have a good picture.

  10. Ever notice how the vast majority of these people look like they’ve been just released from some insane asylum?

    • Unpleasant to read coments like this – that’s how amarmists talk about skeptics. Frankly, we’re better than that,

      • Not unpleasant at all, Javert; my comment is accurate. What’s REALLY unpleasant is the number and incendiary level of actual threats and lies that alarmists direct toward those of us who call a spade a spade in both climate science and the deplorable behavior of alarmists.

  11. Wadhams notably didn’t suggest that other scientists were afraid to back him up lest they die mysteriously. IIRC, a year or so ago he suggested that he feared death after some other alarmists had inexplicably died. (A case for Loony Lew.)

    • The UK Telegraph also looked at Wadhams’ failed sea ice predictions on Oct 8, 2016. Other UK Professors are distancing themselves from Peter Wadhams.
      Instead of short term bold predictions, Prof Andrew Shepard of University College London points to the consensus belief that Arctic sea ice will disappear in the coming decades.

      • I haven’t seen your blog before. Quite interesting. I attempted to leave a comment on one of your political threads but I do not think that it was successfully posted. I commented:

        I agree with David Davies that Brexit means.

        the UK leaving the European Union. We will decide on our borders, our laws, and taxpayers’ money

        There is much debate whether the referendum vote means a hard Brexit. Obviously it does for the reason cited by David Davies. We have voted to leave the EU, and this means out of all the various institutions that make up the EU, eg., out of the single market, out of the common agricultural policy, out of the common fisheries policy etc.

        One cannot leave/get off the train by keeping one foot in the carriage. We have voted to leave the train and that means getting out of the carriage.

        One can also see from the way that Remainers framed the debate that they too considered that voting out inevitably means a hard Brexit and out of the single market. Their project fear was based upon a hard Brexit.

        At no time did Remainers suggest that a vote out of the EU would mean that the UK would still be part of the single market, and therefore there should be no economic problems, nothing would change economically even if the public was to vote out. At no time did Remainers suggest that there would be no down turn in the stock market, house prices, employment, no need for any emergency budget since economically there would be no change in our relationship with Europe because we would still be part of the single market. As I say, project fear was based entirely upon the consequence of the national vote to leave the EU meant that the UK would have a hard Brexit.

        Democracy is at a junction. If the political class will not act on the vote and seek to curtail it by a soft Brexit it will further demonstrate that there is no government by the people for the people, but instead government by the elitist few for the benefit of the elitist few.

        Politicians need to be very careful, or they will quickly lose even more trust and will be seen to be an irrelevance.

      • Hi Richard.
        Thanks for the kind comments about my blog. You comment there was caught in moderation.

    • It’s getting harder to make predictions about the past. Who knows what it will turn out to be once NOAA, NASA, EPA have fiddled with it?

      • A fungible past is a standard socialist/communist tactic. The past is whatever we say it is in order to fit the unchangeable future.

      • Oh, here we go. It’s only the left/liberals/communists who rewrite history. Yeah, of course.

        The victor gets to write history, independent of where he fits on your naive black/white polarisation of politics.

    • In the wake of Peter Wadham’s (and Paul Ehrlich’s, James Hanson’s, Tim Flannery’s
      et Big Al’s ) failed climate predictions, these failed predictions should be confined to
      the dust bin of history – errata, along with the illuminaries who made them.

  12. “…I don’t feel confident — it’s simply that this is the trend shown by the sea ice volume in recent years, and since that volume is now quite small, it ought to reach zero within one to two more years…”

    No, the trend should not hit zero.

    • I believe zero arctic sea ice is an asymptote, and can never be reached, which is why Wadhams uses 1M sq Km as a proxy for “ice free”, but even 1M may not be reachable even under the worst-case prediction for this century and beyond.

  13. “Settled science, anyone?”

    Vanishingly settled. Scientism in flux, in service to a cause. And a paycheck.

  14. His comments about the Thermohaline ocean circulation and the agreenland sea clearly indicates he doesn’t even understand how this important issue works so I think one can just ignore this space cadet from now on.

  15. Oh course he’s certain that the Arctic will be ice free in 2 or 3 years. And if need be be in another 2 or 3 after that. The math is very specific how how much heat is retained and the models show catastrophic events as far as the eye can see, but somehow the date on the Arctic melting is … We Were Too Early…
    Any day now a hurricane will hit … and if not this this year then next or the year after that… we are in real trouble here folks ! I mean the Arctic.

  16. “Why do you suppose more scientists aren’t being as outspoken in their alarm and concern over what is happening there and what it means to the planet?”

    Um, probably because the science/evidence doesn’t support your position. So, they don’t think it’s true.

  17. Peter may be suffering from various diseases related to aging such as Alzheimer, Dementia, Diabetes, and many blood related ailments and their debilitate effects on human organs such as the brain.

    Very sad.

  18. Is that a “selfie” of Wadham? ( he looks a bit out of “something” but that must be his cheap cell phone I guess) If so, I wonder what’s on the “whiteboard” behind him, I tried figuring some of it out, but couldn’t make hide or hair out of it. Oh, I get it now, those are his theories about Arctic Ice

  19. The Waldham predictions fail are quite clear. With a downward trend ultimately the sea ice extent will be negative. Since this is not possible, the trend is not real, namely time and ice are independent variables, so the trend has no statistical meaning. Trends only work on dependent variables. But, time does not make ice, so they are not dependent. Waldham doesn’t understand basic statistics, and it shows. His time-climate predictions have no statistical meaning. Therefore, there is no point listening to him. He does not have the capacity to understand that the basic principle of his predictions of time-ice is false. Although, if we do make negative ice (anti-ice) that will be something interesting to study. It would seem that if ice and anti-ice meet, it could exterminate climate, or something like that.

  20. “As sea ice melts in the summer, it exposes the dark ocean surface. Instead of reflecting 80 percent of the sunlight, the ocean absorbs 90 percent of the sunlight. The oceans heat up, and Arctic temperatures rise further.”

    This is categorically untrue. This supposed positive feedback effect is incompatible with the data which shows that rate of ice loss has SLOWED since 2007 not increased.

    FAILED HYPOTHESIS , try again.

    • The quote about 90% of the sunlight being absorbed in an iceless arctic shows that he lacks even basic scientific understanding of optics geometry. Most here know that as the angle of incidence increases (like the suns rays as you go poleward) the greater is the amount of light reflected back out into space (more of the vertically polarized portion WILL go into the ocean but the horizontally polarized reflected portion reduces greatly after latitude 75 degrees. This is, of course, on top of the greatly reduced insolation per square metre as we go poleward. The warming of the ocean by insolation is small indeed. Warm air blowing up into the arctic and warm water under the ice does the job – not insolation.

  21. What really puzzles me is how somebody who calls himself an expert can refer to the earth’s atmosphere in such a simplistic way.
    One should expect the scientists of all people, to understand the sheer complexity of the planet and the impossibility of mankind (at least at this stage) to replicate these complex and mostly ill understood processes.
    Sad days for science.

    • Yep. I was going to point that out. I may be temporary, though. In some graphs it is out of the 2 standard deviations zone.

      • Weather. It’s what caused the low this year, it’s what caused the fast recovery and it’s what is causing the slow down now. Meteorologists must bang their heads on a desk when they see people trying to manipulate weather events into something more than they are.

  22. “Through 2016, the linear rate of decline for September is 87,200 square kilometers (33,700 square miles) per year, or 13.3 percent per decade”

    The trend lines on extent and volume still show an essentially ice free summer arctic ocean between 2025 and 2035.

    and the ice state after this year in terms of thickness/age is not at all good.

    Wadhams is essentially right… the trends show we are heading for ice free. Given a melt season like 2012 again, the record is inevitably going to be broken (we hit second lowest this year in a year of poor melt conditions).

    If its 2017, or 2020, when we get to ice free then its still a big problem, even if Wadhams was 1 to 5 years out…

    • Surely if the ice melted to be joint with 2007, you can’t really say they were poor melt conditions, can you? You would surely need to say the conditions favored melting. Of course, if what you mean is that if something that didn’t happen had happened instead, then things might have melted more, I could say if 2007 and 2012 didn’t happen and something else happened, bla bla bla.

      I’m curious as to how being ice free (excusing the weird definition) for a few days in September causes any “problem”.

      Maybe it will happen one day, who knows, but continuing to predict when and being wrong each time would surely cause any rational person to rethink their hypothesis. In fairness, IPCC don’t claim any of these death spiral scenarios and we shouldn’t resort to picking a few outliners to be a representation of the view.

      • “continuing to predict when and being wrong each time would surely cause any rational person to rethink their hypothesis”

        You’re think the clowns who believe this stuff are rational, John?

        Assumes fact not in evidence.

      • But you can.

        Insolation in June and formation of melt ponds drives summer melt in most years.

        In a year with poor insolation and fewer melt ponds like 2016, melt result should have been indifferent -and here we are with a second lowest (or 2007 tie under NSIDC measure)

        The latest NSIDC report confirms that:

        “Although the onset of surface melt was early over much of the Arctic Ocean, as the melt season progressed, a pattern of stormy weather set up….. Such conditions have been previously shown to limit summer ice loss”

      • You haven’t explained how a few days of ice free (either the real term or IPCC term) would be an issue.

      • By golly it does resemble Obama’s economic growth, good catch Gareth. But, like arctic ice, you don’t expect the economy to go to zero I’m sure.

  23. Predicting a date for the demise of sea ice is just daft. It undermines confidence in climate science. On the other hand saying that there is no problem and sea ice cover is in an expanding trend is just as bad and undermines the argument of sceptics just as efficiently.

    • It is a trend for the past 9 years (increase of the minimums, because 2007 was so low), so the only thing you can then say is that 9 years isn’t a relevant time period. You would be quote right to say it. Just like it is also right to day that the first half of the 2000s, which started the death spiral talk, were also a short period of time.

      Ultimately, the only thing that can prove an increase or decrease one way of the other is time. Until then, there aren’t any proposals to do anything about it, not that would have any impact anyway.

    • Climate “science” undermines itself perfectly well 24/7. It needs no help from Whacko Wadhams.

    • Fortunately, the demise of the glaciers in Scotland turned out well for the kilt wearing inhabitants of said country.

      Who is to say the demise of summer ice won’t turn out equally well for someone. Only the Eeyores* in the environmental movement will continue to be depressed about it.

      * https://en.wikipedia.org/wiki/Eeyore

    • I’d say yes, you are right.

      and the conditions which cause it to reach certain levels are the climate of the arctic…

  24. I’m concerned we are in for a Karlization of sea ice and ENSO data. The ‘problems’ and seemingly outright neglect of longstanding data sets this past year has been a prelude to adjustments to land and sea surface temperature, sea level and other sets in the past.

    Remember Hansen simply pushed the US 1930s and 1940s temp records down below 1998’s in 2007! We even had emails pop up between H and an underling on the progress of the fudge. They saw 1998, as the last opportunity to get a new world record temp and this was scotched by the dreaded ‘Pause’ .
    Y’all remember the Pause? They were emboldened to ‘Just Do It’. It fell to Karl since he was retiring anyway.

    Anyone heard anything about the plight of mountain glaciers lately? They were hyped by the UN up until 2007 too. They’ll be retooling measurement methods in use for over 100 yrs as well. BMO in Oz is probably sharpening their pencils. The Climateers have taken a big hit in Oz this past year. Oh, and have you noticed that your local weathermen have magnified the ‘feels like’ temperatures? “It’s 24C today but it will feel like 35!”. They are also already pondering changing the 150yr old definition of hurricane landfall to include near misses. And ya know that old which a call Simpson scale for storm wind speeds needs an overhaul.

    • Arctic sea ice may be a valid metric, but we have NOT yet measured even a single half-cycle.

      When we know more, we “might” be able make some other conclusions. Until then, we are only considering the impact of a single half-El Nino cycle, or half an AMO or PDO.

      • I agree with Gamecock. It responds over time to a rise in air temperatures and fluctuates with ocean oscillations in addition to wild swings due to winds. In other words, it doesn’t really tell us more than what we already know, and can in fact mislead us, which of course the Alarmists want. They also love the fact that they can use one of their favorite type of arguments, the Appeal to Emotion, since ice is something tangible they can point to as “disappearing”, and intimate that we should be all shocked and alarmed about it.

  25. So basically this guy with the PhD (I’m just guessing he is just a research quack not a medical one) hanging on the wall and a whiteboard with impressive looking formulas scrawled on it…knows just as much about the future of arctic sea ice and melting trends as this armchair climatologist with an MBA that has nothing to do with the field hanging on the wall.
    Glad these guys are worth all the grant money!

    • He’s been studying it for decades – including many years of field research.

      As have the NSIDC – founded in 1957…

      and they and other institutions who have been studying the arctic for decades – from before the 1979 satellite data started – conclude the trend is down.

  26. World sea ice is very low at the moment. Given that antarctic sea ice was at record levels in recent years, it is now currently showing no signs of getting back to those level.

    • Paul
      World sea ice is very low at the moment. Given that antarctic sea ice was at record levels in recent years, it is now currently showing no signs of getting back to those level.

      ??? What?
      Antarctic sea ice (maximums, minimums, and averages) was steadily growing ever-larger from 1992 through 2014 – when it set record HIGH maximum sea ice extents. 2015 – up through the beginning (at the beginning of the record-high El Nino ?) of September 2015. Since September 2015 it has oscillated above and below the long-term average.
      You cannot make any claim of any sort of “new trend” from one year at average levels after 22 years of increasing levels.

      • “You cannot make any claim of any sort of “new trend” from one year at average levels after 22 years of increasing levels.”

        Wanna bet?

      • MarkW, quoting RACookPE1978,
        “You cannot make any claim of any sort of “new trend” from one year at average levels after 22 years of increasing levels.”

        Wanna bet?

        So, one year of average Antarctic sea ice (during a record-setting El Nino year) after 22 years of ever-increasing antarctic sea ice extents. What is the trend?

  27. Another way to conceptualize Arctic Amplification is to think of the Global climate as the dog and the Arctic as the tail. It is clear that the Arctic is highly variable, like a wagging tail. But wagging tails don’t actually control that much of the dog. Peter is obsessed with the tail, and obviously gets it wrong.

    • The arctic is variable in that different weather in different melting seasons produces variable results, but the trend is down…

      and the fact is that the arctic ice is an indicator of wider trends – i.e. it is a clear indicator of warming

      • He he,Griff,

        Many warmists like you, have been predicting NO Summer sea ice in the region,for years now, always wrong it is a boring trend. You need to try something else to bother people with.

        It has been shown the decline has rapidly changed to near zero since 2007.It has been shown that important changes in the weather has showed up, with a reducing melting time frame and less unfavorable winds as well. It has been shown statistically the decline has nearly flattened out. It has been shown to YOU repeatedly in another blog,that the AMO is cooling down,which favors the increasing survival of Summer ice in the region.

        You have also been shown in another blog, of a number of published science papers,showing that for a few thousand years in the early Holocene,there were little to no summer ice. You have also been shown that sea ice changes are connected to the AMO changes.

        Yet you refuse or ignore all this because you like Wadhams, are infected by the dumb CAGW conjecture.

      • No, a wagging tail is not controlling the dog.
        The Arctic, blowing heat out of Earth into space even faster when ice pack is down, is not a predictor of more warming.
        It takes deliberately ignoring climate history of the arctic to confabulate a crisis out of the current sea ice levels.

      • People have been predicting that if the trend continues there’ll be no ice.

        The trend is quite clear.

        And if people misrepresent the statements on the lines of ‘if the trend continues as it did this year we’d see no ice in..’ then that’s skeptics twisting what they said.

        It is dishonest to take only the two points of 2007 and 2016 extent and claim there’s no downward trend or it has stabilised.

      • griffyboy, you make my day each time with laughter

        just a question: is then the cooling and expanding antarctic an indicator of wider trends such as global cooling?

  28. “sea ice retreat from the Greenland Sea has prevented the formation of chimneys ”

    He just pulls this stuff out of thin air or where the sun never shines, doesn’t he? It surely smells. There is no report of downwelling water not happening in the North Atlantic. Studies of the Gulf Stream, looking at sediment cores from between Florida and Cuba, indicate that the Stream speeds up in warm conditions and slows down with cold, which is the opposite of what he is saying. This fits perfectly with the fact that cold water has higher viscosity than warm and would thus be slower to flow. Duh!

    What many “climate scientists,” who like to think that they understand the Arctic, do not realize or refuse to recognize is that solar input to the Arctic is pathetic even at the peak of Summer. Summer sunlight, with the sun at such a low angle, must take a long path through the atmosphere at a low angle which, from atmospheric absorption, makes sunlight ~17% of direct sunlight from overhead. Also, the energy delivered per unit area is spread out due to the low angle, such that it is ~17% of normal overhead energy delivery. Taken together, at the peak of Summer, solar intensity is about 3%. Call it 5% and it is still not a lot of energy. This small amount of energy absorbed by open water would be quickly canceled out by ongoing evaporative cooling. In addition, there is indeed quite a bit of reflection of water at this low angle, so it is not all absorbed. Furthermore—it’s so much fun as junk science can be refuted in so many ways— this 5% insolation is only aat the peak of Summer. During most of Summer, the Sun’s angle is even lower and it is dark for six months. Solar energy input is a non-starter as far as warming the ocean goes.

    Arctic Summer melt is caused mostly by injection of warm water into the Arctic basin, such that the warmer, lower density water would hug the underside of the floating ice and melt the ice from below. Warm air from the south, replacing dense bodies of cold air that flow south toward the equator, also causes melting but not as efficiently as does the warm water.

    The low Arctic ice of 2007 was a perfect storm involving at least two major factors. The North Atlantic Oscillation (NAO) pumped a large bolus of warm water into the Arctic basin, dominant winds of that summer blew a lot of ice out of the Arctic basin where it melted elsewhere, and there appears to have been some ocean floor vulcanism that might have generated more warm water. None of these effects have anything to do with the junk science regarding that the Arctic is on a melting trend, other than the long-term warming we have experienced since the end of the Little Ice Age. Also, assuming an ever-continuing warming trend is ingenuous as history clearly shows that warm periods and cold periods do not last forever and it is likely that the cyclic warming and cooling that we have seen for thousands of years are most likely to continue.

    Pushing the meme that we are on a warming path no matter what thus becomes a political push designed to persuade normal people to allow the government to make changes to their lives that they normally would not tolerate and reject completely.

    • If global warming of the air were the cause for alleged Arctic sea ice decline from its century high in 1979, then Antarctic sea ice should also have contracted. But instead, it has grown dramatically.

      CACA hypothesis falsified. QED.

    • “and there appears to have been some ocean floor vulcanism that might have generated more warm water”

      No there was not. There is no ocean floor vulcanism influencing arctic sea ice melt.

      Insolation is a vital component of summer ice melt.

      • so the gakkel ridge one of the least understood ridges wher explosive volcanism happened on depths before not believed to have made this possible doesn’t exist? hmmmm griff you seem to be very selective

  29. This is the text of an email I sent Professor Wadhams today. I await his reply.

    Dear “Professor” Wadhams.

    Here you go again, reiterating your failed predictions.

    There are only two possible explanations for your behaviour.

    1) You are a shameless charlatan, more concerned with your own personal publicity, rather than the actual science.
    2) You have my sympathy as you are clearly delusional and require medical and/or psychiatric treatment.

    By the way my last bet, which you did not respond to, still stands.
    I bet you £2000 that Arctic sea-ice extent will not fall below 1 Wadham* at its lowest next year (2017).

    • I do, too! And I have been wondering for weeks, What happened to Jimbo?

      About a year ago (?), something happened to make him stop posting on WUWT. He was SUCH fine, highly informative, and frequent commenter — then, after a few posts on WUWT, here and there, ___________________________________ . Silence.

      Whatever the cause (and if Jimbo was hurt, I sure wish the one(s) who hurt him would make it right), WE MISS YOU, JIMBO — please come back!
