When I was a kid, I’d watch cartoons with mad scientists running amok and causing trouble. As an adult, I observed that there actually aren’t any mad scientists. Now, after reading Dr. James Hansen’s latest essay, I’m not so sure anymore.
I have been told of specific well-respected people who have asserted that “Jim Hansen exaggerates” the magnitude and imminence of the climate threat. If only that were true, I would be happy…
…
Climate effects are occurring already and are generally consistent with expectations. The perceptive person should notice that the climate dice are now loaded.
…
CO2, the dominant climate forcing on the long run, will stay in the climate system for millennia…
I was recently at a meeting that included many of the top researchers in climate change. There was universal agreement about the urgency of the climate crisis…if we burn all the fossil fuels it is certain that sea level would eventually rise by tens of meters…Venus – like conditions in the sense of 90 bar surface pressure and surface temperature of several hundred degrees are only plausible on billion – year time scales…
One implication is that if we should “succeed” in digging up and burning all fossil fuels, some parts of the planet would become literally uninhabitable, with some time in the year having wet bulb temperature exceeding 35 °C. At such temperatures , for reasons of physiology and physics, humans cannot survive , because even under ideal conditions of rest and ventilation, it is physically impossible for the environment to carry away the 100 W of metabolic heat that a human body generates when it is at rest 14 . Thus even a person lying quietly naked in hurricane force winds would be unable to survive…
The picture that emerges for Earth sometime in the distant future, if we should dig up and burn every fossil fuel, is thus consistent with that depicted in “Storms” — an ice-free Antarctica and a desolate planet without human inhabitants. Although temperatures in the Himalayas may have become seductive, it is doubtful that the many would allow the wealthy few to appropriate this territory to themselves or that humans would survive with the extermination of most other species on the planet. At least one sentence in “Storms” will need to be corrected in the next edition: even with burning of all fossil fuels the tropical ocean does not “boil”. But it is not an exaggeration to suggest, based on best available scientific evidence, that burning all fossil fuels could result in the planet being not only ice – free but human-free.

UPDATE: Over at Bishop Hill, they discuss Hansen’s other recent non peer reviewed paper:
James Hansen is also getting back into the climate sensitivity fray, posting up an Arxiv preprint that (surprise, surprise) comes up with a much more alarming figure than Lewis or Masters. The estimate is based on paleoclimate data, specifically δ18O data for foraminifera (a class of microscopic animals that got a mention in the Hockey Stick Illusion). However, as has often been noted in the past, these paleoestimates of climate sensitivity are fraught with difficulty as the quality of data on temperatures and forcings in the distant past is shaky indeed.
More and more I think the general alarm sounded by the team over what proxies tell them is based on shaky and inconsistent data. As we’ve seen with Marcott et al, they tend to mold the proxy data into their visions, rather than let the data tell the story honestly.
Hey I finally realize why American astronauts want to use a Russian rocket to get to the ISS.

“Climate effects are occurring already and are generally consistent with expectations.”
Is he referring to expectations from 10 years ago, 10 months ago, or 10 minutes ago?

I think he’s referring to grant funding being consistent with expectations.
“I don’t have to tell you things are bad. Everybody knows things are bad. It’s a depression. Everybody’s out of work or scared of losing their job. The dollar buys a nickel’s worth, banks are going bust, shopkeepers keep a gun under the counter. Punks are running wild in the street and there’s nobody anywhere who seems to know what to do, and there’s no end to it. We know the air is unfit to breathe and our food is unfit to eat, and we sit watching our TV’s while some local newscaster tells us that today we had fifteen homicides and sixty-three violent crimes, as if that’s the way it’s supposed to be. We know things are bad – worse than bad. They’re crazy. It’s like everything everywhere is going crazy, so we don’t go out anymore. We sit in the house, and slowly the world we are living in is getting smaller, and all we say is, ‘Please, at least leave us alone in our living rooms. Let me have my toaster and my TV and my steel-belted radials and I won’t say anything. Just leave us alone.’ Well, I’m not gonna leave you alone. I want you to get mad! I don’t want you to protest. I don’t want you to riot – I don’t want you to write to your congressman because I wouldn’t know what to tell you to write. I don’t know what to do about the depression and the inflation and the Russians and the crime in the street. All I know is that first you’ve got to get mad. You’ve got to say, ‘I’m a HUMAN BEING, God damn it! My life has VALUE!’ So I want you to get up now. I want all of you to get up out of your chairs. I want you to get up right now and go to the window. Open it, and stick your head out, and yell, ‘I’M AS MAD AS HELL, AND I’M NOT GOING TO TAKE THIS ANYMORE!'”
“Good evening. Well, I’ll tell you what happened: I just ran out of bull****. Am I still on the air? I really don’t know any other way to say it other than I just ran out of bull****. Bull**** is all the reasons we give for living. And if we can’t think up any reasons of our own, we always have the God bull****. We don’t know why we’re going through all this pointless pain, humiliation, decays, so there better be someone somewhere who does know. That’s the God bull****. And then, there’s the noble man bull****; that man is a noble creature that can order his own world; who needs God? Well, if there’s anybody out there that can look around this demented slaughterhouse of a world we live in and tell me that man is a noble creature, believe me: That man is full of bull****. I don’t have anything going for me. So I don’t have any bull**** left. I just ran out of it, you see.”
– Howard Beale, Network (1976)…
or will it be James Hansen (2014)?
The statement about 35 C being unlivable is a typical Hanson over simplification error. The evaporation of body water (sweat) would allow heat removal even up past 40C as long as the dew point is well below 35 C, and circulation adequate.
Can someone from Vegas confirm that people with “loaded dice” are also called cheaters?
Imminence. Recently a smart young person told me that she tends to discount global warming as a concern, because of prior assertions that we only had 5 years or 10 years before disastrous consequences — and her observation that not much has changed in the past 5 years.
But then he never explains why the water is not over the West Side Highway.

Tobias and others knocking NASA, please observe:
I am a retired NASA scientist, and a skeptic. Many NASA scientists are outstanding people and outstanding scientists, even if some agree with the CAGW claims. Please remember we sent people to the Moon, and teleoperated vehicles to Mars, etc. However, in every large organization there are kooks. Remember that Buzz Aldren, Harrison Schmidt, the former NASA administrator, and even Hanson’s former boss disagree with him. Your comment is quite out of place. The only reason NASA uses Russian vehicles is due to presidential and congressional politics) flip flopping in NASA directions and funding.
Leonard Weinstein, ScD
RH – Yes it could be possible.
I find quite doubtful though.
The only place I see temps over 120 degrees F is in a desert with a dew point well below 50 degrees F.
Just because something is possible does not make it plausible.
Show me data that would indicate that the places on the earth regularly have dew points in the 80s degree F and in a static state.
Okay, I found a PNAS paper on “wet bulb temperature” exceeding 35 deg. C.:
http://www.pnas.org/content/107/21/9552.full
The authors of this piece (note: edited by Kerry Emanuel) cite GCM model
runs “with a high-CO2”. They present histograms of annual maximum wet-
bulb temperature. This is in support of their contention that people CANNOT
adapt to a world “10 deg. C.” warmer. This overblown temperature is
in the year 2300, with the high-end sensitivity of 4.5 degrees C. for each
doubling of CO2.
Okay, even if the models were correct, even if the extreme warming
far-future scenario they present were correct, even if the human-generated
CO2 remained in the atmosphere for millennia, this paper is wrong.
Simply put, the paper is just making the boring, obvious point that in a world
10 C. warmer, portions of the world would not be survivable by primitives
without access to technology (air conditioning). This point is not
actually stated in the paper.
The paper simply assumes that a “4-to-6 hour exposure to a wet-bulb
temperature over 35 degrees C.” is fatal, and CANNOT be mitigated by
any means other than a fan (the “hurricane” given by the Hansen quote)
or by sweating. There is NO consideration given to allowing the humans
in question access to air conditioning. Thus, my statement above about
the paper’s obvious, boring, and UNSTATED point.
So, 3 centuries in the future, we have to ensure that for
some part of the year, air conditioning is available for most of the
eastern United States, most of the Arabian peninsula, most of Australia,
portions of western Africa, Egypt, much of India, and a small piece of China.
That is eminently doable, as long as we are not hobbled by silly
wind/solar power and overblown environmental regulations.
While Mr. Hansen’s assertion that a person would likely die if exposed to a temperature 95F at 100% humidity for prolonged periods is, technically, true. I feel his argument is also a classic case of misrepresentation. Specifically he is wrong to suggest that, in vast regions, the local relative humidity would to remain at 100% long enough to effect ones health. The problem?… rain cycles and night time temperature cycles.
The bottom line is the local atmosphere’s rain and nighttime temperature cycles continually cool the area altering the relative humidity… so periods of sustained high temperatures with 100% relative humidity are rare.
Anyone who has lived in South America’s tropical areas, where the combination of high temperature and humidity is common, is familiar with earth’s coping mechanism in this situation. Specifically, they know it regularly rains shortly after the mid-day temperature highs and (frequently) later in the evening. In the “wet” season the afternoon rain last approximately an hour… usually pretty intensely. In the “dry” season it simply rains less intensely and slightly less frequently.
The short version: as the local relative humidity increases it begins to rain driving the ground level temperature down and starting the cycle over again.
The pattern’s pretty familiar to anyone who’s lived in such climes. Temperature and relative humidity climb as the day progresses. Rain arrives in the afternoon dropping temperatures below the pre-rain dew point and increasing the immediate relative humidity – at a lower temperature. Then the temperature increases slightly quickly dropping the relative humidity below 100%. Restarting the cycle, some of the rain (by no means all) begins to re-evaporate increasing the relative humidity. The bottom line you end up with wide swings in relative humidity throughout the day.
For example, I lived in the Republic of Panama for a number of years. Over the past 13 years, the average high temperature in Panama City (near sea level) has been 87°F (30°C). The hottest months were February and March (90°F, 32°C), and the coolest month was October (85°F, 29°C). Average nighttime temperatures vary only slightly throughout the year, between 76°F (24°C) and 78°F (25°C). The highest and lowest temperatures recorded in that period were 102°F (38°C) and 68°F (20°C). (see http://www.yourpanama.com/panama-weather.html)
Over the past 11 years, average morning relative humidity has ranged between 87% and 93%, with the lowest months being March and April. Average afternoon relative humidity has ranged between 59% and 81%. On average, October has been the most humid month.
Based on the above it’s pretty clear that, in wet tropical areas, the relative humidity is in a constant state of flux.
Only in a static world, consistent with Hansen’s misbegotten mind, could one imagine conditions where the relative humidity at ground level remained 100% for prolonged periods.

I read this “…some parts of the planet would become literally uninhabitable, with some time in the year having wet bulb temperature exceeding 35 °C. At such temperatures , for reasons of physiology and physics, humans cannot survive , because even under ideal conditions of rest and ventilation, it is physically impossible for the environment to carry away the 100 W of metabolic heat that a human body generates when it is at rest…” and I laughed.
I served in a Police Force in the Far East, in a post where I was permitted to cancel foot patrols when the ambient temperature rose above 35 °C, as ordered by the Commissioner of Police. Mobile patrols continued. The farm-workers in my mainly rural area continued to work, albeit somewhat slower, but life went on.
Oh, the humidity in Summer, when the temperatures were so high was in the region of 90% – 98%, all the time.
Think Hong Kong.
Hansen and his Green Gang of death-eating Luddite sociopaths are nor nihilists but Thanatists, signifying those to whom “Death is the only cure for Life’s disease.” For a full-blown overview of this murderous obsession, we suggest reviewing Paul Ehrlich’s “Population Bomb” (1969), Science Czar John Holdren’s view of humanity as “a mass of seething maggots” (1974), lately such cheerful souls as Keith Farnish, Kentti Linkola, PIK’s Hans-Joachim Schellnhuber– all of a degraded totalitarian mindset worthy of Pol Pot.
Anyone unfamiliar with these names does not appreciate the Green Gang goals common to Briffa, Hansen, Jones, Mann, Trenberth et al. William James’ “Anabaptists of Munster” were kindergartners by comparison.
Reality is that the prophecies are going to be tested. I don’t see China or India curtailing their economic growth and becomig renewable for some time so it is inevitable that CO2 emissions are likely to continue to grow for at least another decade or more.
I have little concern over that – I do not believe these guys anymore – they’re complete hypocrits.
Why the Chinese won’t clean up their smokestack emissions with well tried technology remains a mystery to me.
Surely they’d have tp prefer the improved atmosphere achieved in most western nations through cleaning up smoke stack emissions ?
The CO2 will take care of itself – either increasing biomass or ocean cooling will deal with it.
The problem is you only have to ‘believe’ in something and at the same time ignore the facts (truth), that will quickly take you way beyond reality. It is then promoted by propaganda. Hansen is right in the mix. Then if you oppose him, heaven forbid!
One implication is that if we should “succeed” in digging up and burning all fossil fuels, some parts of the planet would become literally uninhabitable, with some time in the year having wet bulb temperature exceeding 35 °C.
=============
BS. The paleo records show conclusively that the earth has a stable temperature at 22C and 11C. In the not so recent past in geological time scales, long after the “faint sun” ended, CO2 was still much higher than if we burned all known fossil fuels and the earth’s temperature was stable at 22C.

Me thinks that a wet bulb temperature of 95 degree F is impossible.
I have yet to set a dew point above 85 degree F.
It is not at all unusual for at least some days during late July/August in southern Maryland to have afternoon temperature and humidity in the mid-90s. Yes, often it is cooled by a thunderstorm in the late afternoon early evening, but I’ve survived wet bulb temps very close to 95 F fairly often, and I would suspect above that at times as well, without (at least in my youth) any air conditioning beyond a fan.
You know? When they were talking about “global warming” in, response to increasing atmospheric CO2, maybe they might have had the merest smidgen of a point? But when the temperature stopped going up… and they started calling it “climate change”? What they are talking about now is called “weather’.

High Dew Point Temperatures
July 23, 2005
Unusually high dew point temperatures pooled over southern Minnesota during the late afternoon and evening hours of Saturday, July 23. Both Pipestone and St. James reached 86 degrees at 5:00 pm, breaking the old record of 84 that was set at multiple locations on July 20, 2002. During the evening hours on that date, three west central Minnesota locations; Madison, Morris, and Olivia reported dew point temperatures of 84 degrees. Our examination identified one other episode of such extraordinary dew point values. A handful of southern Minnesota locations reported 84 degree dew point temperatures on July 29 and 30, 1999.
Note that there has only been about ten years of higher density hourly dew point temperature readings for Minnesota. The bulk of the automated weather stations were installed in the early to mid 1990’s. The Twin Cities has hourly dew point records going back to 1945.
The dew point temperature at the Twin Cities International Airport on Saturday, July 23 topped out at 80 degrees at 9pm. 80 degree dew point temperatures are rare in the Twin Cities historical record. Since 1945, there have been only twenty-one hours of 80 degree dew point temperatures recorded. Ten of those twenty-one hours came in a ten hour period on July 12 and 13, 1995. The highest dew point temperature ever recorded in the Twin Cities was 81 degrees at 11:00 am on July 30, 1999.
Dew point temperatures in the low 80’s can occasionally be seen across the Gulf Coast and the Upper Mississippi Valley. A handful of locations in the United States have seen dew points as high as 90 degrees F, especially in Florida and Louisiana. Some of the highest combinations of dew points and temperature on earth can be found in the costal regions of the Persian Gulf, the Gulf of Aden and the Red Sea where dew point temperatures as high as 93 degrees have been measured.
The heat index, a “feels like” measure which factors together temperature and dew point temperature, reached 125 degrees at Pipestone, MN at 5:00 pm on July 23. At that time, the air temperature was 93 degrees and the dew point temperature was 86. A quick scan of the historical database reveals only one other heat index value of 125 degrees. An air temperature of 97 degrees teamed with an 84 degree dew point temperature to create a heat index value of 125 degrees at the Red Wing airport at 3:00 pm on July 30, 1999.
[Addendum: July 28, 2005]
In a follow-up investigation, the State Climatology Office discovered that the Pipestone and St. James dew point temperature sensors were reading three to four degrees higher than neighboring stations during June and July of 2005. Therefore, dew point temperatures in Pipestone and St. James reported on July 23 may have been erroneously high. However, both stations are well-maintained, government-sponsored observation sites whose data are widely distributed. Thereofore, the 86 degree dew point temperatures will remain part of the historical database

Could Dr. Hansen come and visit South India? Our summer is not yet in full force but for example in Tirupattur it was 40C at 86% humidity; see http://www.imdchennai.gov.in/rdwr.htm
Thousands of people live and have lived there for millennia.
Not to say that such a temperature is pleasant. On top of we suffer up to 12 hours powercuts a day due to the fact that various Tamil Nadu governments were lured to believe that windmills provide base load and simply planned accordingly. We found out the hard way: they don’t. They only run during our 4 months of summer monsoon. Anyway, big industry go their wind turbines tax free and a few manufactures made windfall profits so not everybody is unhappy.

“It’s often said that genius borders on lunacy. Case in point; Hansen.”
I missed the “genius” part in Hansen, but the lunacy factor always seemed obvious. In psychobabble terms, “The man’s hero complex drove him off into a world of his own invention.”
Unfettered now by job responsibilities, old Jimbo is free to wander off into the really deep grass.”
Whoops;
Andy Warhol called, your fifteen minures “ARE” UP.
Without regard to my poor grammar, PLEASE; JUST FADE AWAY………..
NASA let him go? I cant imagine why. Off his leash, Hansen will be able to unmake that which he made.
Speaking of leashes in this whacky world of alarmism, I am haunted by visions of Grant Foster as Hansen’s self proclaimed “attack dog”. And Saturday night dressups and stuff.
As for “digging up and burning all fossil fuels”, we won’t even come close.
When you add up the huge recent finds in unconventional oil — for example in Australia and Siberia — and all the methane hydrates in the oceans, that’s a colossal reserve. Should humanity survive this century, we will undoubtedly have enough new energy technologies to sustain us without much fossil fuel use.
We’ll use these new energy technologies because they’ll be cheaper than the ever-rising cost of finding and extracting fossil fuels. Also, because we don’t want to continue to pump excess CO2 into the atmosphere if we don’t have to. But not because some activist scaremonger tries to frighten us into throwing away the only chance we have at maintaining an advanced society.
“One implication is that if we should “succeed” in digging up and burning all fossil fuels, some parts of the planet would become literally uninhabitable, with some time in the year having wet bulb temperature exceeding 35 °C.”
Does anyone else you ever wonder, as I do, if any of the AGW alarmists (and Hansen in particular) have actually stopped to consider where all the fossil fuels got their carbon from in the first place?
Please, someone correct me if I am wrong, but I have always been under the impression that fossil fuels are made from plant and animal matter. The animal carbon content coming from plants, and the plant carbon coming, mostly, from atmospheric CO2.
All that would suggest that, prior to being locked in as fossil fuel, the vast majority of that carbon would have been in our atmosphere at some point in the distant past.
The question is, if the wet bulb temperature would make the planet “literally uninhabitable,” the question is begged as to how we ended up with an inhabitable earth at all?
Unless I am missing something huge, then Hansen’s spoutings don’t even pass the most basic logic/plausibility test.
The surface temperature on Venus is because of the very high surface pressure and height of its tropopause, 70KM with ours about 15KM. Its surface gets less insolation than earth due to its high albedo and despite getting twice our insolation. Lapse rate on Venus is just over 10C/km giving 490C for the surface.
