Spectacularly Poor Climate Science At NASA

Dr. James Hansen of NASA, has been the world’s leading promoter of the idea that the world is headed towards “climate disaster.” There is little evidence to back this up.

In 2008, Hansen wrote about “stabilizing” the climate :

Stabilizing atmospheric CO2 and climate requires that net CO2 emissions approach zero, because of the long lifetime of CO2


Yet in 1999, he made it quite clear that past climate was not stable, and that there was little evidence to support that idea that the climate was becoming unstable.

Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath.

In that same 1999 report, he showed that US temperatures peaked in 1934, and declined through the rest of the century.

In 1989, NOAA and the UK’s leading expert agreed with Hansen that US had not warmed.

February 04, 1989

Last week, scientists from the United States Commerce Department’s National Oceanic and Atmospheric Administration said that a study of temperature readings for the contiguous 48 states over the last century showed there had been no significant change in average temperature over that period.

Dr. (Phil) Jones said in a telephone interview today that his own results for the 48 states agreed with those findings.

But in the year 2000, NASA and NOAA altered the historical US temperature record, which now shows that there was about one degree centigrade US warming during the century before 1989.

NASA Fig.D.gif (513×438)

The animated image below shows the changes which Dr. Hansen made to the historical US temperature record after the year 1999. He cooled the 1930s, and warmed the 1980s and 1990s. The year 1998 went from being more than half a degree cooler than 1934, to warmer than 1934.

Hansen’s recent temperature data tampering is not limited to the US. He has done the same thing all over the planet. Below is one recent example in Iceland, where he dramatically cooled the first half of the century, and warmed the present. He appears to be trying to erase evidence that there was a very warm period in much of the Arctic around 1940.

Original version  Altered version

The changes in Reykjavik, Iceland were particularly heinous – because they were specifically objected to by the Icelandic Met Office. Meteorologist Mark Johnson contacted  the senior expert at the Icelandic Met Office and asked him about NASA data tampering in iceland. Here is their exchange :

 1) Are you happy with the adjustments as they stand right now?

No, I am not happy with the adjustments as they stand, but I might no be quite up to date. I don’t know if they have been making additional changes during the last 2-3 weeks.  

2) Have you or any of your staff contacted or been contacted by anyone from NASA Goddard Space Institute officials?

No, but we made some contact with them about 5-6 weeks ago.  Best wishes, 

Trausti Jónsson senior meteorologist Icelandic Meteorological Office

The altering of Icelandic data by NASA was particularly troubling, because the cooling from 1940 to 1980 was a well known and difficult historical period in Iceland. NASA  erased Iceland’s history, without even the courtesy to contact Iceland’s experts.

Additionally, we know that there was tremendous warming in the Arctic prior to the 1940s, which Hansen has erased from the historical record in Iceland, Greenland and elsewhere.

In 1947, noted geophysicist Dr. Hans Ahlmann reported to the University of California Geophysical Institute that the Arctic had warmed ten degrees since 1900.

31 May 1947 – Warmer Arctic Climate May Raise Ocean Levels

Arctic warming was well known as early as 1922.


Many leading experts prior to the Hansen era, agreed that the earlier Arctic warming was real, and quite dramatic.

CLEVELAND, Feb. 16 (A.A.P.) Dr. William S. Carlson, an Arctic expert, said to-night that the Polar icecaps were melting at an astonishing and unexplained rate and were threatening to swamp seaports   by raising the ocean levels.

Leading Arctic expert from 1953

The glaciers of Norway and Alaska are only half the size they were 50 years age. The temperature around Spitsbergen has so modified that the sailing time has lengthened from three to eight months of the year,”

Leading Arctic expert from 1952

LONDON (A.P.).-The earth is getting warmer. The oceans are getting deeper. The glaciers are getting smaller. Even the fish are changing their way of life.

All this and more is going on because of a vast, unaccountable, century-by-century change, in climate. In his study at Bedford College in London, Britain’s distinguished geographer, Professor Gordon Manley, is worrying about it.

Leading geographer from 1950

Dr. Ahlman urged the establishment of an international agency to study conditions on a global basis. Temperatures had risen 10 degrees since 1900. The navigable season along Western Spitzbergen now last- ed eight months instead of three.

Leading Arctic expert from 1947

it was concluded that near Polar temperatures are on an average six degrees higher than those registered by Nansen 40 years ago. Ice measurements were on an average only 6½ feet against from 9¼ to 13 feet.

Russian report from 1940

Similarly NASA temperature records for Antarctica have also been altered. In 2005, NASA showed most of Antarctic on a long term cooling trend, but in 2007 they changed it to a long term warming trend – despite the fact that 2007 was the year of record sea ice in Antarctica.

The map below from 2005 shows long term cooling.

In 2007, they replaced the image above with a different one which incorrectly showed long term warming.

Disintegration: Antarctic Warming Claims Another Ice Shelf : Feature Articles

NASA has been altering data and changing the historical record from one pole to the other. Not surprisingly, the vast majority of these changes have trended towards more warming than the original thermometer readings indicated.


In 1988, Hansen made three very famous forecasts (shown below) of temperature rise, based on high, medium and very low (Scenario C) CO2 production.


His forecasts were very poor, and indicate that he has greatly overestimated the effect of CO2 on the climate. The graph below overlays the most recent NASA global temperatures(red line) on Hansen’s predictions from 1988. The red circle shows 2012 temperature anomalies so far.

NASA reported temperatures show more of an increase than satellites do, but even the NASA temperatures fall below Scenario C – which essentially assumes that people stopped producing CO2 in the year 2000. Hansen’s own data invalidates his theory, yet he continues to ramp up his claims about the magnitude of global warming. This is the mark of a very poor scientist.

Sea Level

Now, on to his claims about sea level. Hansen has consistently made sea level forecasts far above the upper bounds of those from the IPCC (18-59cm.) In 2007, he forecast sea level rise up to 25 metres to the US Senate, which is nearly fifty times higher than the IPCC’s highest forecast.

Antarctic blues and the Australian drought 

In 1988, Hansen told (sympathetic) journalist Bob Reiss that the West Side Highway in Manhattan would be underwater within 20 or 30 years (2008-2018). In 2001, he confirmed and reiterated that claim.

While doing research 12 or 13 years ago, I met Jim Hansen, the scientist who in 1988 predicted the greenhouse effect before Congress. I went over to the window with him and looked out on Broadway in New York City and said, “If what you’re saying about the greenhouse effect is true, is anything going to look different down there in 20 years?” He looked for a while and was quiet and didn’t say anything for a couple seconds. Then he said, “Well, there will be more traffic.” I, of course, didn’t think he heard the question right. Then he explained, “The West Side Highway [which runs along the Hudson River] will be under water. And there will be tape across the windows across the street because of high winds. And the same birds won’t be there. The trees in the median strip will change.” Then he said, “There will be more police cars.” Why? “Well, you know what happens to crime when the heat goes up.”

And so far, over the last 10 years, we’ve had 10 of the hottest years on record.

Didn’t he also say that restaurants would have signs in their windows that read, “Water by request only.”

Under the greenhouse effect, extreme weather increases. Depending on where you are in terms of the hydrological cycle, you get more of whatever you’re prone to get. New York can get droughts, the droughts can get more severe and you’ll have signs in restaurants saying “Water by request only.”

When did he say this will happen?

Within 20 or 30 years. And remember we had this conversation in 1988 or 1989.

Does he still believe these things?

Yes, he still believes everything. I talked to him a few months ago and he said he wouldn’t change anything that he said then.

Stormy weather – Global Warming – Salon.com

Dr. Hansen has also been making wildly exaggerated forecasts about a wide variety of topics for almost three decades, like this one from 1986

The News and Courier – Google News Archive Search

In March 2006, he forecast a “Super El Nino” which went against the opinion of the expert community, and never materialized.

We suggest that an El Niño is likely to originate in 2006 and that there is a good chance it will be a “super El Niño”, rivaling the 1983 and 1997-1998 El Niños, which were successively labeled the “El Niño of the century” as they were of unprecedented strength in the previous 100 years.

– Prometheus: Out on a Limb with a Super El Niño Prediction Archives

In March, 2011 – he again predicted a strong El Nino which never materialized.

Based on sub­sur­face ocean tem­pera­tures, the way these have pro­gres­sed the past sever­al months, and com­parisons with de­velop­ment of prior El Niños, we be­lieve that the sys­tem is mov­ing toward a strong El Niño start­ing this summ­er. It’s not a sure bet, but it is pro­b­able.


In 2012, the NASA model is once again predicting a strong El Nino, which no one else is forecasting.

SST_table.gif (587×507)

Why does James Hansen keep incorrectly predicting strong El Ninos? The reason is simple – they bring the temperature up, and he expects to see that. A very unsophisticated, lazy and ineffective basis for science.

Antarctic Ice

In 1984, Dr. Hansen predicted a large amount of ice loss in Antarctica as CO2 increases. The image below forecasts 40% albedo loss in the Ross Sea (after a doubling of CO2) which corresponds to loss of white, reflective sea ice.


Contrary to Hansen’s forecast trend, Antarctic sea ice has steadily increased – particularly in the Ross Sea.

Excess ice in the Ross Sea shown in the red circle above. This is the region which Hansen forecast peak ice loss.

Conspiracy Theorist?

Dr. Hansen has alluded on several occasions  to the idea that there is a well funded group of people working to intentionally ruin the climate.

James Hansen, one of the world’s leading climate scientists, will today call for the chief executives of large fossil fuel companies to be put on trial for high crimes against humanity and nature, accusing them of actively spreading doubt about global warming in the same way that tobacco companies blurred the links between smoking and cancer.

Put oil firm chiefs on trial, says leading climate change scientist | Environment | The Guardian

“There is a very concerted effort by people who would prefer to see business to continue as usual. They have been winning the public debate with the help of tremendous resources.”

Scientist hits climate change skepticism – UPI.com

Hansen has never provided any evidence to support the idea that skeptics are either well funded or intentionally misleading the public, yet he frequently repeats this claim.

Dr. Hansen has suggested that fossil fuel corporation CEOs are intentionally committing high crimes against the planet – because they don’t believe his spectacularly failed mispredictions.

Hansen went on to say: “CEOs of fossil energy companies know what they are doing and are aware of long-term consequences of continued business as usual. In my opinion, these CEOs should be tried for high crimes against humanity and nature.”

James Hansen: Try Fossil Fuel CEOs For ‘High Crimes Against Humanity

Additionally Dr. Hansen has been arrested several times for committing crimes in “defense of the planet”

 Other NASA climate failures

Dr. Hansen is not the only climate scientist at NASA making spectacular mispredictions. Five years ago another NASA scientist predicted a possible ice-free Arctic in 2012

NASA climate scientist Jay Zwally said: “At this rate, the Arctic Ocean could be nearly ice-free at the end of summer by 2012, much faster than previous predictions.”

Arctic Sea Ice Gone in Summer Within Five Years?

Arctic ice extent is now within a couple percent of normal, and Alaska has the most extensive sea ice ever recorded.

University of Illinois – Cryosphere Today


For the past 30 years, NASA climate scientists under the leadership of Dr. Hansen have demonstrated nearly complete incompetence in forecasting, and they have tampered with data to try to hide their mispredictions.

    “The individual sciences of our epoch have become specialized in these three eternal vital constants the sexual instinct, the sense of death, and the space-time anguish. After their analysis, after the experimental speculation, it again becomes necessary to sublimate them. The sexual instinct must be sublimated in esthetics; the sense of death in love; and the space-time anguish in metaphysics and religion. Enough of denying; one must affirm. Enough of trying to cure; one must sublimate! Enough of disintegration; one must integrate, integrate, integrate.

    • TNSteve says:

      It has gotten worse under the current administration. NASA has been changed into a political organization focused on Muslim outreach and climate research. I am not sure, if there are cultists, money chasers or some other devious reason why they belittle all who disagree with them. It is a shame that Russia controls our trips to space, primary booster rocket for Atlas and now has stated no more future visits to the space station we contributed the most to operate. I know that true science welcomes continued research and would not refuse to discuss the subject with flat “Earthers” or anyone else. We know less today than we will know, unless we slip into another dark age. Why are global warming/climate change pushers so venomous about non believers? If they are right, science will prove them out. It is funny how they support using Middle East oil, not Canadian via pipeline, not US energy independence but continued flow of petro dollars to people that hate the US and use the money to support terrorism and the spread of their radical groups worldwide. The response I got from the Whitehouse about the Keystone pipeline was that Obama did not want to do anything that would increase our carbon footprint Really? Pipeline Vs ocean/truck transport? Same amount of oil? How does that not reduce the footprint? I think many voters are gullible, but politicians are devious. Now, with COMMON CORE they will educate/brainwash our children to ensure the right ideas are in place. Sad ,

      • I’ve wondered similar things, too! I think the venom and ridicule is due to Saul Alinsky acolytes’ adherence to Rules for Radicals. Common Core is insidious, and functions as indoctrination. There are so many contradictions in the current powers that be, as you said. I don’t understand why we’re rushing to pay money to people who hate us, i.e. for petroleum from North Africa and the Middle East, when the U.S. and Canada have such abundant natural resources of our own.

        • Allan says:

          —-i have a IQ of 160—-
          could of fooled me!

          That sort of ignorance has its roots in the work of Thomas Malthus ..(whom the East India Company sent out to inventory the Planet). And its legacy is all around us today as otherwise decent people consider racial genocide “a bit of a shame” but at the same time, “an enivitable consequence”

          ——–The position of Malthus, the classic spokesman of zero
          population growth, is too well known to dwell on here.
          But also Charles Darwin, who essentially viewed man as
          another form of beast, somewhat like a clever ape, took
          his cue from the work of Malthus. As he himself admits,
          it was a reading of Malthus’s An Essay on the Principle
          of Population which prompted Darwin to compose his
          Origin of Species. Vernadsky had during his student days
          encountered the work of Pastor Malthus on population,
          and rejected it outright. Referring to Malthus’ fundamental
          thesis, Vernadsky writes:
          Malthus doesn’t realize that his fundamental results
          lead to entirely different conclusions. You might say
          that they are simply not true, because he did not take
          into consideration the fact that, estimating accurately
          the long-term growth of human population geologically,
          as regards food and the necessities of life, the expansion
          of plant and animals comprising it, must inevitably
          increase with greater force and speed, expressing a
          more rapid rate of reproduction, than that of the population.
          It’s necessary to always have this correction in
          mind. Historically, it is only the irrational elements in
          our social system that make it difficult to clearly observe
          the effect of this natural phenomenon.———- http://www.21stcenturysciencetech.com/Articles_2013/Fall-Winter_2013/Greening_Vernadsky.pdf

While we can do things to improve energy, make it cleaner, new technologies- I’m all for it-we do not have to take the kind of steps the Obama people are claiming we have to take. I truly hope the scare tactics don’t work. I have heard enough scientists trash such reports of doom as totally unfounded by data to realize that it is all highly exaggerated and agenda driven.

  15. TNSteve says:

    It is a shame that Obama has reduced NASA to prove climate change and Muslim outreach, both of which should not be primary objectives to a once great AMERICAN institution. I do know figures never lie, but liars figure. I think in some cases people are blinded by money or their cult like blind belief that leads them to deny other, science, continued open minded research and call all who disagree flat earthers and ignore them. I always though science is never settled, otherwise we would have stopped many years ago when the answers of those days was so well known. Regardless, it is shameful how data is being used, abused and pushed as absolute on the masses. I still think follow the money and who owns carbon credit exchanges.

  16. Doug Cotton says:

    Yes, James Hansen was a key figure from the early 1980’s as I point out on my website where you’ll see links to my new book “Why it’s not carbon dioxide after all” now available for less through eBay (around $15) or $5.95 through Kindle. If you are interested in learning about the new 21st century paradigm shift in climate science you’ll find an explanation therein for all planets. .

  17. TNSteve says:

    Is true science ever really settled? Follow the money. Soros likes collapsing countries and their currency making billions. Now, Soros and Gore have a great Ponzi scheme, using environmental cultists, western guilt and crooked politicians to make billions , maybe even trillions off controlling the carbon credit exchanges, They will not work unless the west commits and redistributes their wealth tot he third world where the man made carbon credits are purchased and traded via the exchanges. The irony is pollute just pay for it! It is beyond me how so many people are believers. I hope the real independent scientists keep seeking the truth .

  19. VincentDV says:

    Brian Kinney has a point though. With a growth rate of 1%, it takes only 70 years to double the world population. If nothing stops the population from growing, ultimately the whole earth surface would be covered with humans (which won’t happen because of food shortage, disease and other gloom & doom).

    But he is wrong in thinking this is inevitable. Well developed regions like the U.S. and Europe have a growth rate close to zero. We don’t need to annihilate 90% of mankind, there’s a less cynical and more humane solution: help, facilitate and allow the development of the third world.

    P.S. I have an IQ of 974 so my remark is superior to Brian’s!

  21. Sirws says:

    Interesting summary of alterations over time.

    Scenario C prediction, as a trend over decades and not year by year, is actually pretty good in capturing the ballpark movement and order of magnitude; especially using 80’s supercomputer technology and dynamic climatology theory. An 8 degree latitude by 10 degree longitude grid point model around the global is pretty freakin’ coarse for simulating any kind of reality.

    I acknowledge that Hansen asserted that C was the least likely outcome for the future as far as projected greenhouse gas emission levels go but then this is also not a dynamic atmosphere-ocean model. The ocean is considered but is static and non responsive to changes in the atmosphere such as wind patterns that would affect the transportation of warmth by the ocean (it is assumed fixed at estimates for the climate of the day); and the ocean only responds in a simplistic manner to changes in the air temperature directly above the grid point where the calculations are made. The ocean in this 1988 model has no depth or movement (i.e. currents) simulated.

    And that’s not to mention guesses as to exactly when a significant volcanic eruption would inject atmospheric cooling aerosols aloft in the model (may explain some of the noise between predicted and observed lines where they don’t line up).

    The red dot the author has added is irrelevant on this plot for comparison purposes because the lines show 5-year running means not individual years let alone portions thereof. This point value is therefore not directly comparable with the line of Scenario C.

  22. Gene Eggleston says:

    The following statement appears in many supposedly scientific proofs that global warming is not happening.
    “Contrary to the forecast trend of the models, Antarctic sea ice has steadily increased – particularly in the Ross Sea.”
    This is a sure sign the source is fraudulent. Sea ice increase was specifically predicted by most climate models. Technically it is not ‘sea-ice’. It is fresh water ice formed from water rapidly and increasingly running off the Antarctic land mass. Fresh water freezes at a higher temperature than sea water. So any source that claims to be knowledgeable about climate change and denies global warming based, at least in part, on increasing Antarctic ice is either a liar or ignorant.

    • geran says:

      Gene, your last sentence needed a little rework: “So any source that claims to be knowledgeable about climate change and accepts global warming based, at least in part, on anything from Hansen, NASA, or any other tax-funded agency, is either a liar or ignorant.”

    • Very laughable. People like you will be prosecuted for crimes against humanity for the long term. You are a testament to the US educational system — meaning – because I am sure you need interpretation — you don’t understand what science is. Cherry picking data or events isn’t science. This is done by people who are funded – not by the government – by by the carbon interests (oil, coal, and natural gas).

          as the baby boom generation retires and the population of golf courses peaks
          there will be more falls onto hard astro turf putting greens resulting in more head injuries than would occur with natural grass

Stop knowing all and do some research outside the grant money circle. Also check money trial behind carbon exchanges. Soros, gore own them n they make money not less co2

    In the U.S., the politcal debate about climate change is over, and the warmists lost big time. The liberal, progressive, left wing Democrats were crushed in November, even though they made a big issue of “climate change”. I truly hope the crazed, left wing climate scientists keep making a big deal about the issue. Have protests, scream from the pages of your favorite left wing newspaper. It will only accelerate your losses in 2016.

    Whenever someone mentions the name James Hansen, I just say, “Please don’t talk dirty to me”.

    Just for fun, let’s look back at the first two paragraphs of his testimony before the Energy and Natural Resources Committee of the United States Senate on 23 June 1988, about his certainty that the record high temperatures were the result of human activity:

    “Mr Chairman and committee members, thank you for the opportunity to present the results of my research on the greenhouse effect, which has been carried out with my colleagues at the NASA Goddard Institute for Space Studies.

    I would like to draw three main conclusions. Number one, the earth is warmer in 1988 than at any time in the history of instrumental measurements. Number two, the global warming is now large enough that we can ascribe with a degree of confidence a cause and effect relationship to the greenhouse effect. And number three, our computer simulations indicate that the greenhouse effect is already large enough to begin to effect the probability of extreme events such as summer heat waves.”

    That was in June 1988… and today we know what a load of bullshit it was… “we can ascribe with a degree of confidence a cause and effect relationship to the greenhouse effect…”!!!! Really?

  26. Miles Izzo says:

    Minor point: in your “Sea Ice Extent” graphic, the Weddell Sea is circled, but you’ve called it the “Ross Sea” in the text below. In the graphic, it appears that the region near the Ross Sea has indeed decreased in ice, thus confirming Hansen’s prediction. It would be prudent to correct this.

    Antarctican ice has no relation to Arctic ice. Indeed as Antarctica has such subfreezing temperatures that as the world warms up it indeed might see more snow. But the earth would still be warming up. Charts on this section that show arctic ice extent don’t extend to September when the ice is at a minimum. I recommend the following site.

    No one is waiting for climate change to happen, it’s here. We don’t get rain, we get flash floods. The West has record drought and most likely record flooding with the El Nino phenomenon the strongest ever seen. With all the fires, mudslides will be terrible. Flooding so bad in Indiana where I live drowned crops and made it impossible for farmers to get in the field. Every year gets warmer. How can anyone really believe climate change is a hoax to get more grant money for scholarly articles? Many here I guess. Where do you people live? in some dome that doesn’t get “weather”? It’s easier to pretend it isn’t happening since this scenario is terrifying. This is like the parents who won’t vaccinate their kids because they want to believe it’s better for them. Well, you won’t have to be a skeptic much longer, have fun kids.

    • You have absolutely no idea what you are talking about. The Southwest and Rocky Mountains are very wet. Indiana was much hotter in the 1930s.

      If you studied history, you would know that climate is cyclical.

    • Colleen , its best to keep quiet and let everybody think you are stupid than to speak and remove all doubt . The earth is 4.6 billion years old and you are looking at the last 10-20 years and say they are indicative of what is happening , NO , the stories much more complex than that and requires some effort to be put in , go and obtain some historical data on weather and climate for the last 100 years and see .

  37. amosbatto says:

    This is an incredibly deceptive article, written by someone who doesn’t know the first thing about climate science. I am probably wasting my time, but I will attempt to explain the problems with this article.

    First of all, a lot of Hansen’s predictions are based upon paleohistory. We know that during the Eemian, which was the last interglacial 120 thousand years ago (MIS 3e), when CO2 reached a maximum of 300 ppm in the atmosphere, the temperature was roughly 1 C warmer than today and the sea levels were 6-9 meteres higher. The last time the Earth had a similar atmosphere as we have today was during the late Pliocene, 3.5 million years ago, when there was 360-400 ppm of CO2, the sea level was 22.5 meters higher today and the temperature was 2-3 C warmer than today.

    So we know from paleohistory that our atmosphere today of 400 ppm of CO2 will produce much higher temperatures and much higher sea levels in the long term. The debate is how long will it take before we come into energy balance and the temperatures will stop rising. Currently the oceans are absorbing 93% of the total heat, whereas the atmosphere only absorbs 2%, so we still haven’t experienced the majority of the heating, which will come in the future. It takes a long time to heat up the ocean which is an average depth of 4 km deep. Likewise, it takes a long time to melt the Greenland and Antarctic Ice sheets, so there is a lag between the changes in the level of greenhouse gas effects in the atmosphere and the changes in the temperature and the sea level. Eventually, however, the ocean will stop absorbing heat and the heat it has absorbed will start being emitted into the atmosphere, which will warm the temperatures. Likewise, as the icesheets melt, there will be less ice on the planet to absorb heat. Currently the Earth is absorbing more energy than it is emitting, but eventualy this energy imbalance will end and we will see the same temperature and sea rises that occurred in the past when the level of greenhouse gases was increased.

    The big debate among the scientists is how fast will the changes occur, not whether they will eventually occur. James Hansen and a growing number of his collegues believe that the change will occur much faster at an exponential rate, but the consensus view as expressed by the IPCC is that these changes will occur much slower at a linear rate. There is a growing body of evidence from the paleohistory that sea level change and temperature change reaches tipping points and then changes very quickly. Hansen and his coauthors have looked at that evidence and predicts that the same will happen today. After having read a half dozen of the recent articles by Hansen et al., I find their arguments very convincing why we can expect rapid climate change in the future. Based on the paleoclimate, they argue that we need to reduce the CO2 levels to 350 ppm, or possible to 300 ppm if we want to stabilize the climate.

    Now this article criticizes Hansen because he has predicted back in the late 80s, that we will start to see rapid temperature and sea rise within 20 or 30 years time. Predicting when tipping points will be reached and strong feedback loops will kick in is extremely difficult, especially in 1988 when there is was limited data from the ice cores and ocean floor samples. Today we have much better paleoclimate data, and most climatologists agree that abrupt climate will probably happen if we continue on the current path. They just don’t agree when it could happen.

    If we stabilize the level of greenhouse gases in the atmosphere at today’s levels, almost all scientists will predict that the sea will be roughly 25 meters higher than today in the year 4000, because they can see that from paleohistory, but is very hard to predict how soon it will rise, because we don’t have good models for how ice sheets melt, nor to the models incorporate the topography of Greenland and Antarctica. Likewise, it is very hard to predict how fast temperatures will rise, because we have to be able to model heat flow in the oceans, cloud formation, and many other things which are not well understood.

    Most models used by the IPCC Assessment Reports have left out important feedback loops, so they predict linear change, but the paleohistorical record shows climate change doesn’t occur linearly. Most feedbacks aren’t well enough understood to acturately model them. For example, we know know that roughly 25% of the warming which has occurred was caused by the disappearance of 40% of the area of the Antarctic sea ice which changed the Earth’s albedo, but most models still don’t incorporate the positive feedback from melting ice. Nobody is sure how to model the way that rising acidity in the ocean and rising temperatures are reducing the phytoplankton which is the biggest carbon sink on the planet. There has been some modeling of tropical forest dieback, which is the second largest carbon sink on the planet, but again, the CMIP5 models used in the IPCC’s Fifth Assessment Report don’t include that positive feedback.

    The real disagreement among climate scientists is whether we should take drastic action now as Hansen argues because abrupt climate change is possible by mid-century or whether we can reduce greenhouse gase emissions gradually, because the radiative forcing has to be much higher to cause abrupt climate change.

    This article argues that we can’t trust NASA scientists because they have mispredicted highly stochastic events like annual ice melt and el niño. Yes, professional scientists do get this stuff wrong occasionally, but this article cherry picks a few mispredictions. For example, I could just as easily point to the time that Hansen et al. accurately predicted the temperature change and change in radiative force that would occur from the SO2 that was released by the eruption of Mount Pinatubo in 1991. Short term weather prediction is highly variable, but long-term climate trends are much less variable, and prediction is much more reliable.

    Most of the “evidence” presented in this article is cherry-picked and doesn’t present the whole picture. The Arctic sea ice has lost 70% of its volume since the late 1970s. Both Greenland and Antarctica are loosing ice volume at accelerating rates. The growth of sea ice around Antarctica is actually a result of climate change, but looking at Antarctica as a whole shows that it is loosing ice. Likewise, just looking at one season’s ice growth in the Arctic and ignoring the trend over 40 years is not honest science.

    As for the argument that NASA GISS is manipulating the temperature record, that argument is frankly baloney. Here is what the GISS FAC has to say about:
    Q. Why can’t we use just raw data?
    A. Just averaging the raw data would give results that are highly dependent on the particular locations (latitude and elevation) and reporting periods of the actual weather stations; such results would mostly reflect those accidental circumstances rather than yield meaningful information about our climate.

    Q. Can you illustrate the above with a simple example?
    A. Assume, e.g., that a station at the bottom of a mountain sent in reports continuously starting in 1880 and assume that a station was built near the top of that mountain and started reporting in 1900. Since those new temperatures are much lower than the temperatures from the station in the valley, averaging the two temperature series would create a substantial temperature drop starting in 1900.

    Q. How can we combine the data of the two stations above in a meaningful way?
    A. What may be done before combining those data is to increase the new data or lower the old ones until the two series seem consistent. How much we have to adjust these data may be estimated by comparing the time period with reports from both stations: After the offset, the averages over the common period should be equal. (This is the basis for the GISS method). As new data become available, the offset determined using that method may change. This explains why additional recent data can impact also much earlier data in any regional or global time series.

    Another approach is to replace both series by their anomalies with respect to a fixed base period. This is the method used by the University of East Anglia’s Climatic Research Unit (CRU) in the UK. The disadvantage is that stations that did not report during that whole base period cannot be used.

    More mathematically complex methods are used by NOAA National Centers for Environmental Information (NOAA/NCEI) and the Berkeley Earth Project, but the resulting differences are small.

    • Jason Calley says:

      Hey amosbatto! I think you have done a great job of presenting the orthodox (note that I do not say “consensus”) opinion of CAGW. Pretty much everyone who frequents Tony’s (aka Steven’s) site is well aware of those arguments. Many, perhaps even most, sceptics started with a nominal acceptance of the current orthodoxy. The scepticism only came after we started looking in more depth into the scientific and logical basis of those arguments, and found them to be unconvincing.

      For example, you say, “So we know from paleohistory that our atmosphere today of 400 ppm of CO2 will produce much higher temperatures and much higher sea levels in the long term.” Really? Does that logically follow? What is the error band on the 300ppm CO2 from the Eemian? Do we know whether that CO2 was responsible for the warm climate, or was it perhaps the result of the warmer seas outgassing CO2? If we are in danger of a climate tipping point today, why did the climate not tip during the Eemian when it was warmer? Or during the Holocene Climatic Optimum much more recently? Yes, the radiative properties of CO2 work to make it a greenhouse gas — but those properties only give a doubling rate of about 1 degree, and that is only in an atmosphere where water vapor is excluded. When the H2O IR overlap is included, CO2 effects become MUCH smaller. If increased water evaporation serves as a 3 or 4 times multiplier, why did that not happen during the Eemian? In fact, ANY source of warming would start the H2O feedback, even the H2O feedback triggers more H2O feedback, so how has the climate not gone run-away a billion years ago? Does it make sense that a system with positive feedback will be stable (cyclic, but still stable with no run away) for hundreds of millions of years? Even more tellingly, the distinctive marker for CO2 induced warming is a hot spot in the upper troposphere. That marker has not been observed, therefore something else must be responsible for any current warming.

      We could go on and on and on, but the ONLY thing I have ever seen that convinced a warmist to change was when they did their OWN research. For example, you say, “As for the argument that NASA GISS is manipulating the temperature record, that argument is frankly baloney.” I would urge you to look over https://chiefio.wordpress.com/gistemp/

      Pretend you are a Martian, cold, logical, impartial. Look at the data. No, not the “adjusted” data, the numbers that have been changed with only a hand waving justification which does not allow another person to replicate them — the actual numbers with realistic error bars.

        Excellent response, but climate cult and politicians will never be open minded, it seems. I think the primary drivers now for a few is power, control and money. They want to set up carbon credits, broker the deals on the carbon credit exchanges they set up, using the CC they provide to all western governments . All made up, do they must start a panic and absolute acceptance of their crustal mission to save mankind. Once there they broker the CC exchanges taking a percent of the commodity exchange and money pours in for really nothing. Obama had declared to greatest threat to mankind is climate change. Nothing els just climate change. Insane, global terrorists is not. I think oceans, sun and natural events drive 98 to 99%, not man. But to get control , power and money man must believe the sky is falling and it is our fault . Of course climate does and gas happened and will control to happen. I just don’t believe redistribution of wealth and making money is the answer. Since when is science absolutely settled , except on this issue? Cultist mAy never be reached, but you effort to explain is appreciated .

    It’s desperately sad to watch a knowledgeable reader like Mr. Calley trying sincerely to explain how difficult it is to produce entirely clean data, and have him answered by Mr. Goddard’s two-word reply “moron alert”. Mr.Goddard means that Mr. Calley is a moron, which is a mistake. Mr. Calley’s piece is actually well-researched and he is able to make subtle distinctions between similar phenomena; i.e. he understands how science works. Mr. Goddard does not have a clue how science works, and a post consisting of the words ‘moron alert’ signals that on some level he refuses to learn how science works. That doesn’t mean he is stupid; only that he is too lazy or arrogant (or frightened of climate change, which would be a sign of some intelligence) to make the effort.

    (Ee>Ep+E1at) = (E>P+1at)
    What is the most difficult scientific question of global hydroelectric that no one scientists could the answer to it?
    Now the hard global question!
    How can we produce clean energy in a best way by the potential of water Static head in dams & seas that this water pressure can push to the center of planet?
    This is by getting benefit of joint scientific formula (E>P+1at) with immersion turbines method inside the water of dams & seas (Immersion turbines of series and parallel in zero point of opposite forces).
    Ee= High pressure clean energy that is produced by the water power plants in the depth of water via released fixed potential energy of water natural pressure (More than ten meters of water) with new method (Immersion turbines of series and parallel in zero point of opposite forces).
    Ep= Released fixed potential energy of water natural pressure in water depth (More than ten meters of water).
    E1at= Amount of energy that is consumed at a small pump of one atmosphere power is the ability (In the same place of the water power plant in water depth).
    This new method is as like as old method of energy production in dams.
    The difference is that the volume capacity of atmosphere can be made with equipment (Boxes cycle of pipes).
    With help of this new formula in any depth of water you can get the powerful clean energy!
    This new method can help us to transfer of volume capacity of the atmosphere to the deep water!
    Natural pressure of water in any depth of water can help to exit water in the boxes cycle of pipes that they installed at the same depth (New power plant of developed hydroelectric).
    This new formula and new method will produce cheap energy in the world and they can change the world soon!
    Now this scientific new formula and this new method that has been registered officially by the Ministry of Justice of Kurdistan Regional Government under the No. 952/6 from 12th of June,2013 and it has been accepted officially & scientifically by all relevant ministries of KRG. This important and worldwide subject will obtain clean energy that we can say it is parallel to the attempts of Mr. Obama, The president of United States of America for Cutting Carbon Emissions by 30% by 2030 The importance of this invention is to decrease the rate of carbon and decrease the duration from 2030 to downwards.
    I am an environmental researcher and inventor. I could answer of the most difficult question of global hydroelectric. It is normal that you do not believe, but it is true really. For more information: (Only alternative for the future of the human energy that has just been discovered)
    The latest research achievements of water science:
    Discover a new scientific formula of water (Answer of the most difficult question of global hydroelectric):
    Do not worry because new formula discover can solve the world environment problems (Ee>Ep+E1at). The use of oil and gas has ended really! This new formula works with its new method (Immersion Turbines in depth of sea in zero resultant forces). Thus in power generation, water does not exit from the dams! This is a new industrial revolution in the world. All the scientists in the world are in the shock now. With this great discovery will solve the problem of global warming too. It is a scientific fact. I found the answer a question of science that hundreds of years, scientists are looking for answers. Now the time has come to say that we could find a new theory to produce clean energy more powerful than atomic energy:
    The scientific use of the formula (Ee> Ep+E1at) and the most advanced new method of producing electricity from immersion turbines in depth of seas and oceans water. With amazing discover of a new clean energy formula in depth of water (E>P+1at). The immersion turbine method in depth of sea is the base of this new model. This invention can change the world and it can start a new industrial revolution in the world. Many scientists believe that the discovery of the formula is unparalleled. Although many still in shock! How this formula has not be discovered by scientists in the world. This invention is patented in Department of Justice in Kurdistan of Iraq No. 952/6 on 12/6/2013. You can read the articles of (Change the world with Kurdistan ’s industrial revolution) and (A Kurdish inventor has found a new method for electricity production under water).
    I do not have to navigate on the surface and at depth. This new formula works with its new method (Immersion Turbines in depth of sea in zero resultant forces). Thus in power generation, water does not exit from the dams! This is a simple form of advanced technology. Constant power plants in water can helps to transfer the energy to the cities. Power transmission cabling system must be secure and safe of industrial. My work is not too important! I just answer a scientific question. Answer to a hard question that scientists are searching for hundreds of years. My new formula and new method can change the world and start a new industrial revolution soon. This invention is patented in Department of Justice in Kurdistan of Iraq No. 952/6 on 12/6/2013. All the scientists have accepted this theory. Investigate the truth is simple. I have to say that this method is very new. It is different from with all the old ways of hydroelectric that we knew them (Hydroelectric of dams and waves and lagoon power plant). Note: This new solution and this new formula invention in Iraq and Turkey to formally accepted. http://rudaw.net/NewsDetails.aspx?pageid=110844
