Scientists Cleared of Misusing Global Warming Data 541

Hugh Pickens writes writes "The NY Times reports that an inquiry by the Commerce Department's inspector general has found no evidence that NOAA scientists manipulated climate data (reg. may be required) to buttress evidence in support of global warming after climate change skeptics contended that e-mail messages between climate scientists that were stolen and circulated on the Internet in late 2009 showed that scientists were manipulating or withholding information to advance the theory that the earth is warming as a result of human activity. 'None of the investigations have found any evidence to question the ethics of our scientists or raise doubts about NOAA's understanding of climate change science,' says Mary Glackin, the agency's deputy undersecretary for operations. The inquiry, requested last May by Senator James M. Inhofe, Republican of Oklahoma, who has challenged the science underlying human-induced climate change, comes at a critical moment for NOAA, as some newly empowered Republican House members seek to rein in the EPA's plans to regulate greenhouse gas emissions, often contending that the science underpinning global warming is flawed. Inhofe says the report (PDF) was far from a clean bill of health for the agency, and that contrary to its executive summary, showed that the scientists 'engaged in data manipulation.'"

      I'm no climate scientist, but as I understand it, there is a lot of data that is showing the climate changing. As I understand well above the 95% confidence level.

      The real issue is how much of that is man made. There it's more of an indirect relation, in the sense that the climate has been heating up at a rate that seems to be higher then ever before, since we started putting greenhouse gasses into the atmosphere in large quantities. There are also clues that there is a cause and effect relationship between the two, but as I understand that's less clear.

      The actual climate change can be measured. The increase in greenhouse gasses can be measured. The link between them is a theory dependant on our imperfect understanding and ability to model the climate of the entire world. But there are many other influences as well, like solar cycles, volcanism besides the man made greenhouse emission.

      In the end it boils down to if you want to find out if the theory is correct by waiting to see it happen, or if you dislike the future the theory predicts so much that you want to act now in the hope that if the theory is correct, the worst case scenarios can be avoided.

      A pure experimental scientist would do nothing and see if his theory is right. But some of those guys also use themselves as a guinea pig to test how much G-forces the human body can withstand (John Stapp).

          My problem as a mere computational physicist who has looked at some climate modelling codes, which are nothing but computational physics (being done, for some reason, by climatologists) is that every one I've looked at has significant issues. My very favourite was one that did not conserve energy natively, but had energy conservation imposed upon it by adjusting cell temperatures after every time-step. Why they chose to adjust temperature rather than wettness was not clear, although I guess probably becasuse it was computationally easier as the latter would require an additional adjustment to transport terms lest non-conservation of mass creep in.

          Again, as a computational physicist who has modelled a considerable range of systems from the apparently simple to the obviously complex, GCMs look to me like a collection of ad hoc kludges and hopeful parameterizations. They are perfectly good science, but not even close to what is required for policy setting.

          And the real problem is that there is no argument for anthropogenic climate change that does not pass through climate models as a critical step.

          Ergo, the claim that the human role in climate change is anything like certain is to me just a statement of ignorance about the complex and delicate realities of computational physics, which as I said, is in this case for some reason not being done by computational physicists but by climatologists.

          We really don't have a choice regardless. Oil IS running out. Wikileaks had some documents from Saudi Arabia showing that thier reserves are actually 40% smaller than publicly advertised. But even if they weren't, even if the oil reserves were infinite, Saudi Arabia is expected to become a net oil IMPORTER around 2040 or so.

          There are only so many place you can drill for oil there and so they have a hard time increasing production while at the same time they are consuming more and more as they grow.

          I read an article two days ago saying that if Algeria goes like Libya then oil will probably hit $220 a barrel by the end of the summer. Oil is no longer a stable energy source.

          Now as the price goes up it will become economical to harvest more difficult sources like oil shale. However with the easy reserves we have right bnow it takes 1 barrell of oil to produce 4-5 barrells of final products. Easy oil shale sources are something like 1:1.5. This may improve a little with development but not by much.

          We can recognize that climate change/global warming is a bad thing and that CO2 is a primary cause and gradually move to other sources OR we can not and be forced to move much more quickly causing much greater economic damage having had a extra 15-20 years of increasing prices.

The link between them is a theory dependant on our imperfect understanding and ability to model the climate of the entire world. But there are many other influences as well, like solar cycles, volcanism besides the man made greenhouse emission.

        While nobody's proven that the current extraordinary warming trend is man-made, scientists have been very successful in ruling out the other causes you mention (even in combination). The current warming is not caused by volcanism, changes in solar radiation levels, etc. Which means that it's either (a) man-made (a theory for which there is good evidence) or (b) it's due to some completely different force that we don't know about (aliens, the earth's core going out of alignment, mutating neutrinos, ok, I kid).

        Either (a) or (b) should be a subject of concern for us. In fact, I think that if you're inclined to rule out (a) then you'd better be working damn hard on figuring out what (b) is.

        But more importantly, while the theory begins with experimental science, it's now mostly an exercise in risk management. We know that there's a phenomenon occurring, we know that it may prove very --- if not catastrophically --- costly to our society, and we know that industrial waste emissions are probably (meaning, with some very reasonable probability) the cause of it.

        So the question is: from a cost-benefit perspective, what's the best thing to do about emission levels today? Obviously the answer to that question depends on your evaluation of all the factors. However, given that the costs seem quite high (especially when you factor in the low-probability outcomes), you don't need anything approaching absolute proof to justify reducing GHG emissions --- even if there's only a moderate probability that it helps, you can justify it against the potential costs. I think that that the science is firm enough to justify pre-emptive GHG reduction.

            There is one key difference: the recession is a datum observed and then explained after the fact. Global warming was predicted before there was the ability to measure it, as far back as the 19th century.

            It was based on a very simple, reasonably obvious model: CO2 absorbs infrared. Burning fossil fuels increases CO2. That the climate would warm up is a single step in reasoning.

            The details of it are governed by many, many more variables, and as such can be compared to the economy, but it's very important not to be misled by the comparison. This is not a model constructed after the fact, explaining only the data in the past. It is a model which was constructed over a century ago and for which a century of experiment corresponds well with the prediction.

        There are certain fingerprints we can look for to determine whether the current warming is caused by increased carbon. For instance in 1896 Svante Arrhenius predicted that nights should warm faster than days if there is an increase in greenhouse gasses. If the warming was due to increased solar activity we should expect days to warm faster than nights.

        There are other indicators as well. With an increase in greenhouse gases we would expect the poles to warm faster than the equator, and winter to warm faster than summer. These are all fingerprints that we are able to detect. This gives us confidence that we are attributing the warming to the correct cause.

      There really is no evidence of data 'fiddling'. NOAA makes the raw data available. They make the adjusted data available. The process they use to adjust the data (to account for relocation of weather stations/urban heat islands/etc) is also available and part of the peer reviewed literature.

      A retired meteorologist named Anthony Watts did a great job of validating the robustness of the data. He (and a small army of volunteers) rated the weather stations based on how well they met requirements. Weather stations outside of urban areas and away from pavement were rated a 5. Poorly placed weather stations were rated a 1. He had hoped to find that poorly placed weather stations were responsible for the warming trend. In the end it was found that well placed weather stations actually record a greater warming trend. The reason for this may be that the warming trend of poorly placed weather stations is masked by the artificial heat in the area.

      Most locations in the world are oversampled. We have high confidence in the results for those areas. Some locations such as Antarctica are under sampled. We have less confidence in the results for those areas.

      Luckily we also have satellite data since 1979. The satellite data confirms the weather station data.

        Wow, that's quite a misrepresentation of Anthony Watts website [wattsupwiththat.com]. Pretty much the opposite of his conclusions, in fact.

        Articles on his blog (which sometimes reads more like a scientific journal) show that rural stations often show no warming at all - at least, until they have been appropriately "adjusted" (using methods that are generally not released). Meanwhile, the increasing temperatures of urban stations are not adjusted to eliminate the Urban Heat Island effect. Large parts of the arctic and antarctic are presumed to be warming, even though there are no weather stations within hundreds or thousands of miles.

        Is the climate warming? He would agree with you that the climate warmed through (plus or minus) the year 2000 so, but possibly has now entered a cooling phase. Articles on his blog also show that (a) over decades, there is a warming/cooling cycle that very closely follows solar cycles, (b) that the overall warming trend of the past 200 years predates any significant human contribution to CO2 in the atmosphere, (c) the planet has in the past been warmer than today - in that sense, the recent warming is not "unprecedented", and finally (d) millions of years ago CO2 levels were much, much higher than today, so a higher CO2 level is also not unprecedented.

        In short: the earth warms and cools. We do not understand all of the factors that influence these climate cycles, but CO2 is almost certainly not a precursor of increased temperatures. In any case, a warmer earth is in many ways preferable to a cooling earth. The entire panic about CO2 is politically driven, and many scientists have hooked their wagons to it, in order to get research funding.

        My take is that Anthony Watts wants to present the objective truth - whatever that may be - and to discredit bad science and politically driven science.

        Oil is generally not used for electricity production in the United States. Coal is +/- 50%. I know there's supposed to be some decent ways to make coal fuel, but it generally doesn't translate well and I'm not particularly confident we could ramp up coal production enough to quench our thirst. The only real solution imho is to migrate most commuter traffic to full electric. Then it doesn't matter where that electricity comes from: nuclear, coal, oil, wind, hydro, solar, etc. No matter how it goes, it's

    “It also appears that one senior NOAA employee possibly thwarted the release of important federal scientific information for the public to assess and analyze,” he said, referring to an employee’s failure to provide material related to work for the Intergovernmental Panel on Climate Change, a different body that compiles research, in response to a Freedom of Information request. " Mann's manipulation of data and failure to provide information about his research have been a long standing joke. http://www.technologyreview.com/Energy/13830/ [technologyreview.com] It was really no surprise that he wouldn't want to provide the information. What is a giant surprise is that he is still in a position of any responsibility. Well maybe not so much if you want trillions of dollars to be spent on changing the country's energy economy.

      if you want trillions of dollars to be spent on changing the country's energy economy.

      It'll need to happen sooner or later. Even if you don't believe in AGW at all (and you're an idiot IMHO if you don't) we're going to run out of fossil fuels eventually. We can spend trillions now or face total disaster. I say spend the damn money.

    • It riles me that the press still refers to the Emails, that CRU was legally obligated to release under FOI requests as stolen. The folder they were in was listed as FOI, and was located in a publicly accessible FTP server yet they are consistently called stolen by the MSM.

  • ...should be taken out and shot. Seriously:

    The NY Times reports that an inquiry by the Commerce Department's inspector general has found no evidence that NOAA scientists manipulated climate data (reg. may be required) to buttress evidence in support of global warming after climate change skeptics contended that e-mail messages between climate scientists that were stolen and circulated on the Internet in late 2009 showed that scientists were manipulating or withholding information to advance the theory that the earth is warming as a result of human activity.


  • If this had failed, think of all the people who bought solar panels and had done the ROI math based on state and federal credits, rebates, incentives.
    Without the CO2 issue, this could have looked bad. With the expected rush over carbon reduction schemes, wow :)

    If you have actually followed the debate that arose over the infamous "hockey stick" graph that erased the medieval warm period and little ice age (McIntyre and McKittrick) and sundry additional papers since, you know that while they may or may not have done anything to the data per se, they've abused the hell out of statistical analysis, for example experimenting with untested and unstudied methodologies until they get one that shows warming, then publishing results obtained using it without giving any hint of the fact that what they are doing is most sketchy. I've been following this with great interest for just under a decade now, and IMO there is absolutely no question that this has been repeatedly done in the past (by MBH and nearly all the papers on which any of them have collaborated) and continues to be done today. And I won't even go into the bristlecone pine problem and the general problem of using tree-ring proxies for temperature when tree ring thickness is not a monotonic function of temperature only.

    For example, a recent paper was published in Science (Steig) that claimed that the Antarctic is warming at an alarming rate. I've read over the paper and the counterchallenge to the statistical methodology used (which basically coarse grained thermal sensors on the thin peninsula that sticks out into the ocean from continental Antarctica until their generally warming trend overwhelmed the generally and clearly trend of the mainland). This all involved infilling data on continental thermal sensors on the basis of temperatures basically on the other side of the continent, an effect clearly visible if one computes the (infilled) sensor-sensor correlation as a function of sensor separation. The actual real (not infilled) sensor-sensor correlation falls off with distance fairly rapidly, as one might expect (Chicago weather isn't like LA's weather). The infilled correlation function shows substantial station correlation out at two or three thousand kilometers. If one simply includes one more principle component in the PCA, this effect disappears, and so does most of the warming; cooling for the last 30 years appears instead.

    Is this lying with or manipulating data or simple lack of competence with statistics? You decide.

    A reliable statistical estimate of warming of the sort that somebody with no horse in the race might do (and the sort that is done in computing the actual global average temperature from satellite data) shows moderate warming from 1957 to 1980, and cooling from 1980 to 2010. The latter, of course, confounds the predictions that as CO_2 goes steadily up, everything gets warmer; the fact that the fifty year warming is completely negligible is anathema to the scientists who make a living from the AGW hysteria.

    Of course, anyone in the world who wants to can go read the climategate emails (or the comments in the actual hockey stick code), where it is made perfectly clear that the "hockey team" set out to erase the MWP and LIA and does anything and anything necessary to defend the AGW conclusion, right up to having journal editors fired if they dare to print a paper that concludes otherwise. Perhaps science is broad enough that they did all of this in good faith, although if they pulled these sorts of shenanigans in medical research e.g. verifying drug safety there would be immediate, permanent, negative sequellae. But it doesn't make it good science.

    Anybody who actually understands statistics and things like R^2 and principle component analysis can read over things and judge for themselves, of course. If I point out that R^2 for the infamous hockey stick graph in the extrapolated region was basically 0, you will understand exactly what that means...

    AGW may or may not be true, but so far it has been a poster child for confirmation bias, incredibly poor statistical analysis, cherrypicking of data (of course it has happened and continues

      It is not true that satellites show cooling from 1980 to 2011. In fact, quite the opposite. They agree with land based measurements: http://www.woodfortrees.org/plot/uah/from:1980/to:2011/plot/rss/from:1980/to:2011/trend/plot/rss/from:1980/to:2011 [woodfortrees.org]

      It is also not true that O'Donnel found cooling in Antarctica in his critique of Steig 2009. He found warming. It is also not clear that O'Donnel's methods are better. Perhaps they are, but if so, this doesn't make the authors of Steig 2009 liars or incompetent. There will surely be a response to O'Donnel 2010 that further improves the results. This does not make the authors of O'Donnel 2010 liars or incompetent.

    • The one thing I don't get about people who are skeptical of the consensus, is that you can throw out Mann's work if you want, and there is still mountains of evidence left supporting AGW. I don't know much about Steig's Antartic paper, but I would be willing to bet that you could throw his out also, and find other papers by other research teams that come to similar conclusions.

      Here are 3 completely separate 2000 year climate graphs shown together, from 3 different teams using 3 different methods.

    This is another meaningless assertion made by a political organ absolutely unqualified to make any statement on the matter. Note the sentence "The report was not a review of the climate data itself." The Commerce Department can't clear someone of misusing scientific data, this is as stupid a congress declaring there was no data manipulation a day after the "climategate" leaks hit the news.

    EVERYONE learns this in Freshman - I'm talking HIGH SCHOOL FRESHMAN - Science class. The Scientific method is a process. You write your hypothesis. You design your experiment. You collect your data. You eliminate outliers and match the data to a model that helps predict - according to your hypothesis and formula(e). Will the predicted FUTURE data have outliers that don't come out of your formula(e)? Of course. But if the gathered data fit the curve, that's a pretty good indicator that your hypothesis was a good guess. This is like, the most basic concept in Science that there is. It's not fraud in any sense of the word.

    Everyone learns this. Everyone is required to take at least this minimal level of Science education; at least to get the High School diploma.

    Compare this . . . to the blatant skullduggery that goes on in the pseudoscience of Economics. . . the counterargument that limiting Carbon via Economic Policy - is going to "harm our economic growth". (as if deregulation and tax cuts from 2000-2008 have not CLEARLY and demonstrably done so!). Go on, Doctor Economics. Take your payoff from the Heritage Foundation for your "consultation" - and don't bother to cite your affiliation on your "scientific paper". We believe you. And your Invisible Hand.

    Hell. Let's call this a basic reasoning FAIL - on the part of an entire nation. An entire civilization. An entire species. WTF?
