On Global Warming and the HockeyStick

I commented on this ridiculous idea to reduce global warming... and then saw this Wizbang post on global warming and the Hockeystick. The Hockeystick is the sharp increase in global temperatures over the past 20 years and into the near future, as modeled by a Univ of Virginia professor, Thomas Mann. My previous post discussed the fact that Global Warming is really only an issue in the Northern Hemisphere and that the equator and the Southern Hemisphere either have no net increase in temps or are actually cooling.

Anyway, I thought I'd post some more info on the skepticism that is swirling in the scientific community over global warming since January of this year.

This powerpoint presentation was given by two Canadians in a conference in D.C. The most damning quote from the PPT is this (revealing a willingness to eschew the scientific method in favor of political and social aims, dating back to 1995):

"With the publication of the article in Science [in 1995], I gained significant credibility in the community of scientists working on climate change. They thought I was one of them, someone who would pervert science in the service of social and political causes. so one of them let his guard down. A major person working in the area of climate change and global warming sent me an astonishing email that said "We have to get rid of the Medieval Warm Period."
D. Deming, Science 1995

Or this graph, demonstrating the Medieval Warm Period. The implication? The Earth was much warmer in the past than the current projections. And if you continue into the powerpoint, you'll see that current projections have been called into question by scientists around the globe due to the methods used which create the appearance of a hockeystick even with random datasets.

This article goes into the hockeystick matter as well and is recommended reading.

By the way, interested in having the greatest impact on the lives of people around the world? Interested in getting the biggest bang for the buck? check out the work that's being done by the Copenhagen Consensus (it seems that all Europeans aren't monolithic on these issues either).

Their economic assessments place combating Climate Change as "Bad Projects" (meaning little results for the costs associated with them. More beneficial (and less costly) steps can be taken to provide drinking water, food, and medicine to the impoverished regions of the world than implementing a climate change policy that might reduce the increase in global temperatures by 0.25 degrees centigrade.
