Still More on Global Warming

Greenie Watch has some great links on global warming, specifically dealing with the "hockey stick" debate. "The Hockey Stick", for those of you who haven't followed so closely the debate on global warming, refers to a study from the late 1990's describing the rise of global temperatures as a hockey stick laid on its side with the blade at the right, and pointing up. The long, flat stick portion is the state of global temperature for the last 1,000 years, and the blade, where the line spikes up dramatically, is the years since the Industrial Revolution in the late 1800's. This study is the very foundation of the common view of global warming, hence anything that undermines it is a threat to the global warming lobby.

Recently two Canadians have been publishing new examinations of the underlying data used to create the Hockey Stick that show serious flaws in the math, which is discussed in more detail HERE.

Here's an excerpt:

The hockey-stick image has appeared in countless documents and hundreds of speeches. The opening graphic in the recently-published Arctic Climate Impact Assessment report reproduces the Mann chart as the main springboard to hundreds of pages on climate risks in the Arctic. It is also the core justification for the Kyoto Protocol, which comes into effect on Feb. 16.

Until now, criticisms of the hockey stick have been dismissed as fringe reports from marginal global warming skeptics. Today, however, the critical work of two Canadian researchers, Ross McKitrick, an economics professor at Guelph University, and Toronto consultant Stephen McIntyre, will be published by Geophysical Research Letters, the prestigious journal that published one of the early versions of Michael Mann's 1,000-year tracking of Northern Hemisphere temperatures,

Publication in Geophysical Research sets McIntyre and McKitrick's analysis and conclusions in direct opposition to the Mann research. Their criticism can no longer be dismissed as if it were untested research posted on obscure Web sites by crank outsiders. Their work is now a full challenge to the dominant theme of the entire climate and global warming movement.
