Cooling the Debate

So a climate skeptic, a physicist at Cal Berkeley, thought the data was wrong and he could do better. He even got the Koch brothers to fund the work.

Guess what?

Global warming is real, according to a major study released today [October 20, 2011]. Despite issues raised by climate change skeptics, the Berkeley Earth Surface Temperature study fines finds reliable evidence of a arise rise in the average world land temperature of approximately 1ºC since the mid-1950s.

Analyzing temperature data from 15 sources, in some cases going as far back as 1800, the Berkeley Earth study directly addressed scientific concerns raised by skeptics, including the the urban hear heat island effect, poor station quality, and the risk of data selection bias.

On the basis of its analysis, according to Berkeley Earth’s founder and scientific director, Professor Richard A. Muller, the group concluded that earlier studies based on more limited data by teams in the United States and Britain had accurately estimated the extent of land surface warming.
