Climate change skeptic and physicist Richard Muller co-founded the Berkeley Earth Surface Temperature project three years ago to debunk global warming fears, even getting a $150,000 grant from the conservative Charles G. Koch Charitable Foundation for his work.
Today, however, he writes in the New York Times:
"Call me a converted skeptic... humans are almost entirely the cause."
"My total turnaround, in such a short time, is the result of careful and objective analysis by the Berkeley Earth Surface Temperature project... Our results show that the average temperature of the earth’s land has risen by two and a half degrees Fahrenheit over the past 250 years, including an increase of one and a half degrees over the most recent 50 years. Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases."
"These findings are stronger than those of the Intergovernmental Panel on Climate Change, the United Nations group that defines the scientific and diplomatic consensus on global warming."
The Guardian reports:
In an unconventional move aimed at appeasing climate skeptics by allowing "full transparency", the results have been publicly released before being peer reviewed by the Journal of Geophysical Research. All the data and analysis is now available to be freely scrutinized at the Best website. This follows the pattern of previous Best results, none of which have yet been published in peer-reviewed journals.
