Scientific Journal Nature Finds Nothing Notable In CRU Leak 736

Posted by Soulskill
from the nothing-to-see-here-move-along dept.
eldavojohn writes with an update to the CRU email leak story we've been following for the past two weeks. The peer-reviewed scientific journal Nature has published an article saying the emails do not demonstrate any sort of "scientific conspiracy," and that the journal doesn't intend to investigate earlier papers from CRU researchers without "substantive reasons for concern." The article notes, "Whatever the e-mail authors may have said to one another in (supposed) privacy, however, what matters is how they acted. And the fact is that, in the end, neither they nor the IPCC suppressed anything: when the assessment report was published in 2007 it referenced and discussed both papers." Reader lacaprup points out related news that a global warming skeptic plans to sue NASA under the Freedom of Information Act for failing to deliver climate data and correspondence of their own, which he thinks will be "highly damaging." Meanwhile, a United Nations panel will be conducting its own investigation of the CRU emails.

    ... will be bamboozled. There is nothing new in that. It lies behind all political folly.

    The data that was adjusted was paleoclimate data, and what it was being adjusted to was temperature data (i.e., the more reliable modern temperature data). As far as I can tell, they neither could nor did adjust the measured temperature data.

    The OP did not quote the really important part of the Nature piece :

    Nothing in the e-mails undermines the scientific case that global warming is real — or that human activities are almost certainly the cause. That case is supported by multiple, robust lines of evidence, including several that are completely independent of the climate reconstructions debated in the e-mails.

    The evidence for this is literally all around us. Throw all of the CRU data out if you want. It won't change a thing.

    The source code is another thing that has been taken completely out of context. For example, the "Very ARTIFICIAL correction" in was computed, but the line where it was applied was commented out. This is clearly a case of someone playing around with the output to explore various effects and scenarios. They did the experiment, then commented it out to removed that effect from the production output. Does anyone really believe that a real attempt at fraud would be blatantly labeled in the code?

    FFS, not this shit again. Frankly, given the number of times this has been pointed out, I can only assume that people still mentioning it are wilfully ignoring anything that contradicts them.

    However, one last time. It's commonplace to have multiple versions of analysis code with variations including "artificial" changes. I've done it lots of times, mostly for testing purposes - it's quite useful [1] to know how the output of your analysis depends on variations in the input. Only a small fraction of the code in existence was actually used to process the data "for real". Unless you have some evidence that a) arbitrary modifications were made to published data without explanation in the publication and b) any such modifications were not scientifically justified, please stop with this ridiculous and discredited point.

    Dude, you're not just talking about any journal here. You're talking about THE journal for the physical sciences. This journal has more than a century of scientific reporting as testament to its quality. It predates the Nobel price. It predates the work of Einstein and Schrödinger.

    1) That paper is nearly a year old so the logic that "Now finally counter arguments can be heard" seems a bit specious.

    2) That paper is a complete crock of unrefereed shit. I read 92-94 which are the conclusions and was so confused I went and read the earlier portions. There are numerous fallacies in their assumptions and they get some pretty fundamental thermo issues flat wrong.

    If AGW was actually happening, there would be no need to "adjust" numbers and likewise no need to cover up the leaked emails

    Here in the southern hemisphere we have just started our summer. According to my measurements, it is hotter now than it was six months ago. As you say, there is no need to adjust any numbers, so this means we have proof of global warming.

    But seriously, there are plenty of reasons why you might need to adjust some data. New measuring equipment (from alternative manufacturers), procedural changes meaning measurements are taken at different times of the day or even a different place. An organisation might stop measuring a particular reading and you have to go to another source.

    Remember, these measurements have been taken over many decades through different political administrations, through budget cuts, and through technology changes. Even the reasons for taking a certain measurement might change over time, resulting in new methodologies for data collection.

    This is not just one big experiment. This is a series of thousands of different scientific endeavours all coming together. There will have to be a normalisation process involved.

    I will, however, admit that the researchers should have noted the issues with the tree-ring data in question.

    Good thing they did, then. [nature.com] Only ten years ago, mind you.

    Seriously, this whole "climategate" debacle tends to run like this:

    1- Deniers exhume some e-mail / piece of code which they don't understand, but assume is definite proof of evil scheming on the part of the great academic conspiracy ("Trick!" "Hide the decline!" OMGconspiracy send teh copz!!) .

    2- Scientists post explanation, [uea.ac.uk] showing the deniers' allegations to be baseless (The "hidden" decline in tree ring growth was published a decade ago - see Nature link above; in this very publication, it was shown to diverge from the actual instrumental record after 1960; so for the post-1960 period we basically replace tree rings with the actual instrumental data, because we trust thermometers more than tree rings when the two fail to agree; we cited the relevant articles in the caption for the graph just to be sure).

    3- Deniers completely ignore scientists' explanation, and keep fantasising about their glorious victory over evil scheming scientists. See GP for an illustration.

    Rinse. Repeat.

    To GP and all the folks who keep harping about this "VERY ARTIFICIAL" correction code: the code in question is a one-time code for temporarily re-calibrating the tree ring data. The reason, and the coefficients, are ultimately derived from the Nature article I linked to above. For an interesting hypothesis concerning the source of this code, see comment #147 and linked manuscript on this thread. [scienceblogs.com]

    Why would you prove that which is pretty much known to be false. The retreat was likely caused by the combination of substantially less plant mass and steady state volcanic activity which slowly rose CO2 levels. The rapid acceleration of melt off was aided by establishment of the thermohaline circulation which warmed the NW coast of Europe and the NW coast of North America.

    It's believed that the northern U.S. was covered in a 5,000 foot thick ice cap (some time in the last 100k years). It created the 5 Great Lakes.

    You should rush out and tell a scientist. Maybe they didn't know that the temperature has changed before!

    OK, I am being facetious, but I can never understand why people think that they have discovered something that climate scientists didn't know (or didn't want you to know). Yes, it has been hot before and it has been cold before. The problem today is the rate of change. It is getting hot very quickly in the global scheme of things.

    Also, if Anthropogenic Global Warming were true, why hasn't recorded human history, vis-a-vis, the last 1,000 years or so, shown a consistent increase in global temperatures?

    The population 1000 years ago was estimated to be 300 million. Over the next 800 years, it hadn't even increased to 1 billion. Then in the last 200 years it skyrocketed to 6.7 billion. Prior to 1800 the population increased by an average of 835,000 per year. After 1800 that grew to 27.5 million per year.

    We also invented new ways to really pollute the planet like never before. If technology hadn't changed, we would be polluting the planet 21 times more than we were 1000 years ago. But now we also have coal power stations, aluminium smelters, street lights that light the world while we sleep and over 600 million cars.

    With all this in mind, I really can't see how anyone can think that it is not possible that we are having an impact on the planet. We can deliberately go out of our way to change the landscape, alter the course of rivers, seed clouds to make it rain, convert deserts to farmland and make the Panama Canal. So why is not possible that we could also inadvertently alter the planet?

    Finally, here is a question for all the deniers out there. If the engineering feat required today was to actually warm up the planet, how would we do it? I think that the best answer would be to do what were are already doing today.

    "Sharing data with scientists who already agree with you isn't science."

    I don't defend his apparent attempt to thwart one of the 50 odd FOI request he has on his plate by requesting Mann delete some emails. However I do defend his commitment to opening up the data sources. The HADCrut [hadobs.org] data set has been available on the web to scientists, the general public, and psudeo-skeptics alike for years due mainly to his efforts. However I don't expect easily verifyable facts to stop uninformed wankers from being lead around by nose for fun and profit.

    As the Nature editorial points out a small percentage of that set is still locked up by national governments such as France and is only available to researchers willing to fillout the red tape and wait months to get it, they are leaglly bound not to publish it!!! If not for the efforts of Jones 100% of the data would still be locked up with similar red tape.

    I have no doubt as to the motives of the CEI and their ilk who continually bombard climate scientists with such requests while simultaneously running inumerable front sites for the FF industry (eg:icecap), and doing their very best to smear the reputations of leading climate scientists (eg: Mann, Schmidt).

    The graph was not a demonstration of the skill of their method, it was the cover graph for a report for policymakers. Their actual scientific publications show the proxy record directly. And they did not ignore the discrepancy between the two time series. The "divergence problem" is well known, well cited, and frequently discussed among dendroclimatologists. There are some reasons to believe that trees are now responding to non-climatic human influences which they previously were not subject to, such as changes in atmospheric aerosol loading, CO2 content, and pH of precipitation in some locations. You can debate whether these causes are legitimate or not, but in a graph for policymakers it's not inappropriate to drop the data where you suspect it's contaminated and switch to data you think is more trustworthy. Again, their actual publications indicate the decline which is the whole basis for the divergence problem literature in the first place. It's not like this is some huge secret that nobody knew about or the authors refused to acknowledge.

    Are you a dendrochrinologist? Because you have to be to understand exactly what's going on, but the issue (and it's been known about for AGES, so hardly "hidden") is that when there's plenty of rain, pest species are controlled, invasion of competition is limited, and so on, then CO2 correlates well with tree ring size.

    But the quicker pace of warming has buggered that up and so you can't rely on CO2 and ring sizes to be correlated any more for species that are

    1) in areas now seeing drought
    2) in areas now seeing pest species invading (cf dutch elm disease, etc)
    3) in areas being invaded by, say, southern species that couldn't compete in the colder northern climes

    Which is to say not ALL tree rings display this problem, but enough do that you either have to ignore the data after a point or cut down so far that your error bars make the data practically worthless.

    I thought people have been questioning the modern temp data for a while due to land use and urban heat effect. Climate Audit has been tracking this aspect for a while now. We might be warming, but the warming is not universal and nothing more than what has happened in the past. In the context of 1000-1500 years, the warming that happene between 1950-2000 is nothing to be afraid of. To quote CRU:

    "The principal conclusion from these studies (summarized in IPCC AR4) is that the second half of the 20th century was very likely (90% probable) warmer than any other 50-year period in the last 500 years and likely (66% probable) the warmest in the past 1300 years."

    Before any of this email stuff, climateaudit caught NASA adjusting the output so that the 1940's blip was not more than the latter half of the century. I seem to recall it was a error in how the program was rounding the numbers. Climateaudit made a new graph with 1940's showing the warmest year. NASA reproduced the results and then later produced a new chart that showed the 1990's having the warming year with the 1940's the second warmest.

    To quote another post of this subject (a href="http://strata-sphere.com/blog/index.php/archives/11531">strata-sphere.com):

    "Well, the raw CRU data shows that the first half of the last century (1900-1960) was as warm or warmer than it is today. But even if it was not warmer, it was within the uncertainty of the processed data. But let’s assume this claim still holds water, so what if this was the warmest half century since the beginning of the Little Ice Age! We have only had 3 half centuries since the LIA ended! We all know the Earth has been thankfully warming since this bleak time in humanity’’s brief existence."

    So email evidence of data forgery, refusal to comply with FOIA requests, and attempts to silence dissenting opinion is nothing notable?

    Perhaps Nature considers these part and parcel of regular science. I don't, however, and I think most scientists would be shocked and horrified to learn the new rules.

    Granted, the overwhelming majority of the emails show nothing more than the normal scientific process. Apparently, whomever selected those in FOIA.zip is unaware of the normal peer review process. However, if only by chance, they did find evidence of:

    • A conspiracy to thwart a FOIA request.
    • The appearance, at least, that certain scientists were applying a correction to the data in order to get the results they desired.(the "1940's blip")
    • A revealing email where scientists suggested not submitting papers to a journal which published dissenting papers.
    • A revealing text file "harry_read_me" in which the writer displays ignorance of numeric overflow, missing data sets, and arbitrarily generating missing or unavailable data.
    • A debate about the reliability of dendrochronology data as a proxy for temperature.

    Granted, I may not believe the GW conspiracy theorists, but this development is very troubling. While climatology as a whole is probably unaffected, those making public policy cannot rely on the resuts published by Mann, et al, until the investigation is finished. While this may not have long term effects on the scientific problem of GW, it certainly affects the political aspects of it.

    But then again, if Nature sees nothing wrong with forging data to get the result you want, perhaps all of science is doomed.

    It's been rigged for a while on a few fronts. Nature REFUSED to publish the correction to the hockey stick even when it was conclusively proven to them that it was faulty. So what do you expect from Nature? They didn't even require Mann to release his data! They are bought and paid for scum!

    ..And examine the Mainstream Media's blackout on this subject. BBC had the information for an entire month, and sat on the story. A strange situation unfolded, with that bastion of spin, FOX News, breaking the story with more gusto than a bull in a china shop - whilst every other channel either completely ignored it or attempted to skew the reporting to focus just on the theft of data. Only now are some stations grudgingly giving this story the airtime it merits. Here in New Zealand, not a single TV station or newspaper has reported it at all beyond a brief mention in some dirty back pages.. Even the local New Zealand climate scandal (NIWA artificially adjusting temp graphs) is being suppressed. Instead, the lead stories are absolutely jam-packed with images of melting glaciers and prophecies of imminent doom. Considering that the Tiger Woods Index [blogspot.com]finds "climategate" to be one of the most searched terms at the moment, it appears obvious to me that the mainstream media have a vested interest in keeping this information out of the public mind, at least until after Copenhagen. If this scandal had involved ANY other scientific arena of importance, this would have been headline news. I find such collusion between media conglomerates in keeping this story hushed far more disturbing than the story itself.

    I look at the graph on the Realclimate page and see the line labeled "Oerlemans-2005" showing a roughly .2 degree increase and the "instuments Data" showing around a .7 degree increase. The NASA graphs show temperature ranges between -.2 and +.4 degree changes with the "Tglobal" coming in at about .2 degree increase. Sure a ,5 degree difference is pretty big, but since, as you say, the Realclimate graph does not provide the data, can we even be sure that they are using the same data sets? This is only a "smoking gun" if they are using the same data. If it is from different sets then all you have here are different graphs of different data.

    Thanks for the link, note the headline on the report includes the caveat "some". Here is a link [csiro.au] supporting my claim from a similarly reputable source, note the conclusions are derived from observations not modelling. The WP entry on ocean acidification is also quite informative and includes a number of references. Also the ocean has been acidic in the distant past, softbodied animals dominated during those periods.

    Finally I quote from your link - "“The oceans absorb much of the CO2 that we release to the atmosphere,” Ries says. However, he warns that this natural buffer may ultimately come at a great cost. “It’s hard to predict the overall net effect on benthic marine ecosystems," he says. “In the short term, I would guess that the net effect will be negative. In the long term, ecosystems could re-stabilize at a new steady state. “The bottom line is that we really need to bring down CO2 levels in the atmosphere.”"

    The article merely repeats the same claims as the original poster, and so does not constitute a refutation of my response.

    The fact remains, the divergence problem is not some secret that is being hidden. It is cited and discussed by these very authors (e.g., by Briffa at least back to 1998). As I said, you may disagree with their interpretation of the divergence problem (namely, that it's a non-climatic artifact that only affects recent reconstructions), but you can't claim that they pretended it didn't exist. And, as I said, you can find the actual tree ring series unblended with instrumental data in their journal publications (e.g., Briffa again in 2000, with further discussion of the divergence). Finally, as I said, it is not "fraud" to either truncate the series where you don't believe it's accurate nor to substitute data you believe is more accurate in place of the inaccurate data.
