The Conversion of a Climate Change Skeptic

In an op-ed published in the New York Times, Richard Muller, a UC Berkeley physicist and former MacArthur Foundation fellow who had previously doubted some published reports about global warming, discusses why he changed his view and independent research on the subject by he and his daughter. The money quote:

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.
