From US Newswire:
A new report from the National Center for Policy Analysis (NCPA) exposes serious problems with the historical climate trends reconstruction published by the United Nations' Intergovernmental Panel on Climate Change (IPCC) -- the primary evidence used by policy makers and activists who espouse the theory that human activity is causing catastrophic global warming.

At issue is what is commonly referred to as the "hockey stick" -- a widely circulated image that depicts a 700-year period where temperatures remained relatively constant followed by the last 100-plus years where temperatures have shot upwards. The "hockey stick," created by researchers Michael Mann of the University of Virginia and Phil Jones of the University of East Anglia, is used by the [UN's] IPCC and environmental activists as proof of human-induced global warming.
The NCPA report cites findings from five independent research groups that have uncovered serious problems with Mann and Jones' methodology and calculations, which call into question any of its conclusions. For example:
-- Several researchers found Mann and Jones made errors in the collection and use of varying data from multiple sources, used obsolete data, made incorrect calculations, associated data sets with incorrect geographical locations, inappropriately eliminated specific proxy records that they felt were inaccurate and employed statistical methods that removed long time period trends, such as the widely recognized Medieval Warm Period (about A.D. 800 to 1400) and the Little Ice Age (A.D. 1600 to 1850).
-- Mann published a retraction in the June 2004 issue of Geophysical Research, in which he admits underestimating the temperature variations indicated by the proxy data by more than one-third since 1400, which accounts for why he missed the Little Ice Age. Strangely, Mann still argues this considerable error doesn't impact his conclusions.
-- Further, Legates found the "blade" (or sudden rise in temperature) of Mann's hockey stick could not be reproduced using common statistical techniques, or even employing the same techniques as Mann and Jones.
"Mann's claims that human's have caused tremendous warming over the last 100 years and that the 1990s were the warmest decade are untenable," said Legates. "Looking at the data, the global warming scare appears to be merely 'Mann made' junk science."
Matt's Chat
More "lies" from the Left...color me shocked... I don't have a clue if Mann and Jones lied or not...I do know that he is wrong...There is a political parallel in there somewhere...
Mark's Remarks
Yet, despite study after study, using commonly acceptable and scientifically proven methods of data collection and analysis, the environmentalists continue to espouse this theory that humans are the root of all evil. This is inaccurate. It is an inaccuracy to say that we are polluting so much more today, especially with serious emissions standards like we have and more controls. All this foundation based on a study that, as this article purports, is not even replicable by the standard methods of analysis and observation and calculation.
Guess the enviromentalists don't like facts to get in the way of blind ideology, either....
