Vindication for science: EnviroMENTALists are lying about Kyoto
EFL
This has been a nightmare of a year for aficionados of the Kyoto Accord. After Canada’s ratification of the treaty in late 2002, environmentalists had every reason to believe that few climate experts would dare continue to publicly oppose Kyoto’s science, Russia would quickly ratify the accord and it soon would become international law.
But that didn’t happen. Vlad likes the idea of warmer weather. I suspect that the Rooskies have seen through the lies as well.
Of these, none may have the long-term impact of the paper published yesterday in the prestigious British journal Energy and Environment, which explains how one of the fundamental scientific pillars of the Kyoto Accord is based on flawed calculations, incorrect data and a biased selection of climate records.
Enviros (read commies) lied?? Say it ain’t so!
The paper’s authors, Toronto-based analyst Steve McIntyre and University of Guelph economics professor Ross McKitrick, obtained the original data used by Michael Mann of the University of Virginia to support the notion that the 20th-century temperature rise was unprecedented in the past millennium. A detailed audit revealed numerous errors in the data. After correcting these and updating the source records they showed that based on Mann’s own methodologies, his original conclusion was flawed. Mann’s original version resulted in the famous "hockey stick" graph that purported to show 900 years of relative temperature stability (the shaft of the hockey stick) followed by a sharp increase (the blade) in the 20th century (see graph). The corrected version of the last thousand years actually contradicts the view promoted by the Intergovernmental Panel on Climate Change (IPCC), and removes the foundation for claims of 20th-century uniqueness.
Maybe it contradicts it because of the crazies running the show out of Europe want to dismantle what industrial might the U.S. may have left.
To understand the significance of the McIntyre/McKitrick announcement, it is important to consider how our understanding of long-term climate history has evolved over the past decade.
I have a pretty good idea of how science ran amuck, funded by many of the same socialists who supported Clinton in the 90s.
In recent years, however, the case for solar variations being the 20th century’s major climate driver has become much stronger, much to the consternation of Kyoto supporters. After all, if long before human-induced GHG emission became significant, temperatures were considerably higher than today, there would be little reason to think today’s temperatures were anything unnatural. This was especially true since long-term solar records indicated that both the MWP and LIA were closely correlated with changes in solar activity, and the output of the sun has indeed been increasing during the past century’s 0.6C warming. Supporters of the GHG-induced warming hypothesis desperately needed a "smoking gun" to prop up the need for Kyoto.

Among the many mistakes in Mann’s paper, some appear blatant, some simply careless apparently due to clerical errors (for example, allocating measurements to the wrong years, "filling" tables with identical numbers for different proxies in different years, etc.). In many cases, obsolete source data was used that have since been revised by the originating researchers. As an example of their numerous "truncation errors," Mann’s Central England Temperature series stops without explanation at 1730, even though data are available back to 1659, thus hiding a major 17th century cold period. Similarly, Central Europe data are truncated at 1550, rather than 25 years earlier, for which the data are available, the effect being to remove the warmest data in the series. Of course, no one with an understanding of climate history really believes there was a dramatic temperature spike in the middle of the Little Ice Age. Yet Mann’s data and methodology actually supports such a notion, completely contradicting his contention that there was merely a gradually cooling between 1000 AD and 1900.
Well, that is what you get for partying with the Green aparatchiks and not watching what you are doing. This is all a nice way of saying the work was sloppy and possibly politically motivated.
