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."

Changing the climate, one FDIV at a time.

If only they had caught this earlier...

It would have been nice had they caught this error earlier. Then maybe we could have avoided this year's barrage of hurricanes.

Oh well, at least they caught it well before winter sets in. This should help prevent any severe snow storms and blizzards this season.

They complain when a country rides high atop the shoulders of the poor and pretends its success is due entirely to its morally superior system of Capitalism.

It's not success, progress, or technology that riles the world, it's the subjugation of the morality of the human to the morality of the dollar.


Do people still talk this way?

You sound like like someone living in 1968.
