New NASA Data Casts Doubt On Global Warming Models

bonch writes "Satellite data from NASA covering 2000 through 2011 cast doubt on current computer models predicting global warming, according to a new study. The data shows that much less heat is retained by carbon dioxide in the earth's atmosphere than is assumed in current models. 'There is a huge discrepancy between the data and the forecasts that is especially big over the oceans,' said Dr. Roy Spencer, a co-author of the study and research scientist at the University of Alabama." Note: the press release about the study is somewhat less over the top.

    We should follow wherever the data leads. That's science. Up till now, the data has suggested that global warming is very real.

      That data indicates that Earth is warming up, for a particular period of time. It does not directly indicate that the world is going to continue warming up, nor does it by itself tell why it's warming up (which you need to know to answer the first question).

      Hence why you take the data and build a predictive model. Of course, if you have insufficient or incorrect data, then your model is also incorrect, and so are its predictions. Of course, there are varying degrees of "wrong" - it may be that a model based on this new data would simply show a lower rate of warming, for example; or it may be that it completely demolishes the warming positive feedback loop. We'll see.

      Either way, that's how science works. It starts with data, and a hypothesis based on that data; but you have to continue with predictions based on your hypothesis, and experimentally verify them. And, of course, you should always verify the data as well.

      Input, in this case was the collected data from weather stations, satellites, ice cores, tree rings, etc.

      The historical weather record is not used as input it is used to test the model via hind-casting. The inputs to the models are things such as the strength of gravity, the composition of the atmosphere, the absorption spectra of GHG's, the shape of the Earth's geode, etc. The 'logic" is the laws of physics and chemistry. The algothim that brings them together is called finite element analysis and is used on everything from designing casts for engine blocks to building bridges for them to drive across.

      As for TFA, the author of the paper, Roy Spencer, is a creationist quack who has expanded his quackery into AGW, his claims on anything scientific should be taken with a truckload of salt.

    A few notes about TFA:
    1) The data comes from satellites put into space by NASA, but NASA is in no way involved in this study.
    2) If this study actually significantly contradicts our knowledge of global heating, why has it been published in Remote Sensing, and not a more reputable journal?
    3) They only interviewed the guy from the University of Alabama who lead the study
    4) The author works for The Heartland Institute
    5) They seem to have replaced the words "accurate" and "accepted by the scientific community" with "alarmist"
    6) Source on UN's involvement? Seems like they threw that one in just to go for the "UN = bad" reaction that a lot of people have

    I don't have the scientific background to assess his work on climate change.

    But I do have the scientific background to assess his work on evolution, and from that I know he is some combination of a) a really crappy scientist, and/or b) someone willing to lie/misrepresent science to further their own beliefs.

    Either criteria gives me ample reason to doubt any article he's published. If some qualified and credible scientists investigate and vouch for his paper than I may be willing to give it a second thought. But until then I'm not going to take the word of a known quack just because I'm not trained to disprove his particular brand of quackery.

    We don't live in an ideal world where all scientists treat data objectively. We live in a world where some scientists have a religious and political agenda. In this real world, not all ad hominem arguments are ad hominem fallacies.

    When someone has a history of publishing peer reviewed articles that do not make very bold or striking claims, and then making press releases that do make bold and unsubstantiated claims, it is necessary to point that history out, lest uninformed readers conclude that the unsubstantiated claims are what has been peer reviewed.

    Any claim that CO2 is not causing global temperature increase is an unsubstantiated claim and is not what has been peer reviewed here.

    If the model is flawed, then one should show the flaw in the model... casting doubt on his ability to reason intelligently by referring to the man's beliefs, believing them to be those of a person not capable of clear and cogent thought, as a means of creating doubt for his presentation is not a genuinely valid logical refutation for his conclusions.

    I'm not saying the guy's right... I'm just saying it's not a valid argument to attempt to discredit him by referring to his other beliefs. If he's wrong, then evidence should discredit his model... not him.

    The greatest change of farming conditions around the world today, is the absurd willingness of industrialized countries to burn huge quantities of food. 140mio tons of maize are burned as ethanol in the USA alone - that's one quarter of the world maize harvest or 5% of the world coarse grain harvest. In order to provide less than 5% of the world population with about 1% of their primary energy needs.

    Europe is burning similar amounts of "biofuels", so we're burning something on the order of 10% of the world's grain harvest - and people wonder why Somalians don't have enough money to buy food. More artificial demand through biofuels means higher prices, because when you burn food, food is getting scarce.

    Basic economics.

    I agree that alarmists need to put a lid on it. Running around like your hair is on fire certainly doesn't inspire confidence in the logic of anothers arguments, and it's the thoughtful objective response that intelligent people are more often swayed by. By the way, you should notice the source of the first link in this article is from the leading conservative think-tank opposing the existence of Global Warming. Not exactly the first place I would have gone to for an unbiased opinion.

    The wise person looks a scientific consensus (and yes, makes some accounting for political leanings in either direction.) One looks at many disciplines, meteorology and long term climatology, chemistry, oceanography, biology, ecology, geology. One investigates all the signs, looking for impacts in hydrology and everything from frequency of drought, flood, and changing global micro-climates to large scale animal migrations and the changing timing of spring and fall do the shorter, warmer, wetter winters. You can't argue the ice in the Arctic is vanishing. You can't argue that the chemistry of the ocean is changing (decreased salinity from fresh water melt and rising acid levels from carbonic acid due to rising CO2 levels.) Heat trapping and reflection is incredibly complex. A a single large volcanic eruption (like Mt. Pinatubo) can emit enough SO2 to completely skew the results for any specific decade. That's why you need to look at long term trends over decades and centuries to see where the planet is heading.

    I continue to hear critics of "global weather change" cherry pick items to rail against. I see nobody from that camp providing a cohesive response to tens of thousands of different phenomena all pointing in the same direction. There is sadly little informed debate to the contrary, more and more those arguing against the existence of something serious happening to our environment sound like relics from the flat earth society. I won't apologize for people's shoddy work on either side of the issue. When you deal with people there will always be clowns. I will say that folks with personal axes to grind on this topic simply can't address tens of thousands of intelligent, professional, scientists all over the world who've created a consistent, cohesive body of theory and information that concludes with near certainty that we are dangerously close to destroying our environment through the wanton burning of fossil fuels.

    I have an open mind, show me a body of work with even 10% of the depth, breadth, and diversity, and I will gladly concede that there is good reason the worlds experts on the topics (many topics) touched by this issue.

    The article in Forbes is written by a fellow for the Heartland Institute, one of the numerous front organizations for the coal and oil industries alongside other such groups as "CO2 is Green". The study is not peer reviewed, it has been published *for* peer review, there is a dramatic difference between the two. Beyond that, you have the issue that the study argues 180 degrees opposite to the articles claims. In short, the article is complete bunk, written by a fraud with an attempt to reinforce the positions of those who wish to kill scientific progress and research.
