The attitude of many Russians, in government but especially in the scientific community, towards the anthropogenic global warming hypothesis (yes, it is a hypothesis) is quite fascinating. Many respected Russian climatologists are clearly in the skeptic camp. And last week, the Moscow-based Institute for Economic Analysis called bullsh*t on the Hadley CRUT (yes, the same outfit embroiled in Climategate). IEA points to another, completely different possible scientific sin committed by Phil Jones and the gang:
The IEA believes that Russian meteorological-station data did not substantiate the anthropogenic global-warming theory. Analysts say Russian meteorological stations cover most of the country’s territory, and that the Hadley Center had used data submitted by only 25% of such stations in its reports. Over 40% of Russian territory was not included in global-temperature calculations for some other reasons, rather than the lack of meteorological stations and observations.
The data of stations located in areas not listed in the Hadley Climate Research Unit Temperature UK (HadCRUT) survey often does not show any substantial warming in the late 20th century and the early 21st century.
The HadCRUT database includes specific stations providing incomplete data and highlighting the global-warming process, rather than stations facilitating uninterrupted observations.
On the whole, climatologists use the incomplete findings of meteorological stations far more often than those providing complete observations.
IEA analysts say climatologists use the data of stations located in large populated centers that are influenced by the urban-warming effect more frequently than the correct data of remote stations.
The scale of global warming was exaggerated due to temperature distortions for Russia accounting for 12.5% of the world’s land mass. The IEA said it was necessary to recalculate all global-temperature data in order to assess the scale of such exaggeration.
Global-temperature data will have to be modified if similar climate-date procedures have been used from other national data because the calculations used by COP15 analysts, including financial calculations, are based on HadCRUT research.
This allegation of cherry picking is extremely serious, if true. Certainly, if the data/station selection procedure has a material impact on the results, the procedure should be made transparent (including release the code), and the underlying data should be made available so that others can devise alternative procedures and test the robustness of results to said procedures. Given that (a) the CRUT procedure seems to produce the politically desired results, and (b) the emails that have been released colorably support the allegation that CRUT has an agenda, it is more than plausible that the discarding of the majority of Russian sites was not accidental, or driven by legitimate concerns regarding the quality of the sites and their records. This skepticism would be bolstered if the IEA accusations that the omitted stations were better on crucial dimensions (notably, continuity of coverage and rural location unaffected by the effects of urbanization) are correct. Omitting the stations that a priori would seem superior and getting “warmer” results would be highly, highly suspicious.
This is of course important for understanding the average global temperature data. But AGT is merely a convenient summary statistic, and shouldn’t be given that much weight. What is more important for the purpose of testing the implications of climate models is the spatial pattern of temperature changes–the “fingerprint” of global warming. One implication of these models is that heating should be pronounced at northern latitudes, including in Siberia. And indeed, this is one of the implications that advocates of the AGW hypothesis claim has been demonstrated empirically to support their call for draconian restrictions on carbon emissions.
But, what if this supposed empirical demonstration is based on data subject to a biased selection procedure? If that’s true, one of the main empirical supports for the AGW hypothesis disappears. Thus, the quality of the Russian data is a major, major issue that must be resolved in order to evaluate the empirical validity of climate models specifically, and the AGW hypothesis generally. If the IEA is correct in its assertion that including the excluded stations would result in a lowering of the worldwide average temperature, the effect would be even more pronounced in northern latitudes, and CO2 would not have left the damning fingerprint that would convict it of a crime against Gaia.
The fingerprint evidence is already suspect. Richard Lindzen of MIT has repeatedly emphasized that the tropical troposphere has not heated as predicted by the climate models. That is a big empirical strike against the AGW hypothesis–but one that has not received sufficient attention. If, in addition, the warming at northern latitudes is weaker than has been asserted heretofore based on censored/selected data, or does not exist at all, the empirical damage would be–or at least should be–fatal to the climate models (which emphasize the role of positive feedback effects to generate predictions of dramatic warming).
Thus, of all the fallout from the HadleyCRUT scandal, this could be the most important. The full Russian record should be evaluated thoroughly, and stat, to understand what is truly happening in Siberia.
The American Thinker has a couple of interesting pieces on Climategate. Definitely worth reading is this article by scientists David Douglass and John Christy about the blatant manipulation of the peer review process by AGW advocates masquerading as scientists. I thought it was impossible for me to be more cynical about the peer review process than I already was based on almost 20 years of experience watching the sausage being made, and more than a few times through the grinder myself. I was wrong. This shorter article on the lengths to which AGW advocates will go to control more popular sources of information on climate change science is also quite illuminating.
That drip, drip, drip you hear isn’t rain.
