Key Global Warming Study May Have Bad Mathematics

An anonymous reader writes "Berkeley physics professor Richard A. Muller writes that a key study showing a sudden 'hockey stick shape' increase in global temperature may be flawed from bad mathematics. Stephen McIntyre and Ross McKitrick say that Michael Mann's computer program handled data normalization incorrectly and exaggerated data with a hockey stick shape." Update: 10/18 18:26 GMT by J : Alas for the environment, it looks like McKitrick and McIntyre have been refuted. "In previous rounds of the debate, Lambert has shown that McKitrick messed up an analysis of the number of weather stations, showed he knew almost nothing about climate, flunked basic thermodynamics, couldn't handle missing values correctly and invented his own temperature scale. But Tim's latest discovery really takes the cake."

Re:Junk science strikes again

[Mind-over-matter-mat]

Sustainability is not economically feasible under the current capitalist regime even when current levels of technology are taken into account. Do i have faith that science and technology can solve my problems and undo all the harm? Or do I take to the streets and propose clever and expensive restrictions? Being only one man i feel i will sit at my computer and vent my frustrations in text form... And i don't even know if my vote counts.

Re:Study rejected by the science magazine Nature

[A beautiful mind]

Although its perfect to fuel the middle-aged corporate reasoning. "Remember kids , no such thing like global warming exists, and who says so is an anti-american fascist traitor and will be burned." Thanks god we live in a civilized age. I just hope my irony won't cover the sun and cause mass extinction...
