Two authors of a new study hailed to end the climate change debate once and for all are at odds over what the report actually does prove. Climatologist Judith Curry (photo) accuses her colleague and scientific director Richard Muller of another Climategate trick to "hide the decline." Curry and Muller belong to a team of researchers at the University of California known as the Berkeley Earth Surface Temperature (BEST) project. While Muller claims their research shows global warming of nearly 1°C since 1950, Curry told The Mail on Sunday, "There is no scientific basis for saying that warming hasn't stopped. To say that there is detracts from the credibility of the data."
The BEST graph of global temperatures over the past 200 years reveals a pronounced spike in temperatures since the mid-20th century. Ignoring the fact that climate change skeptics mainly question whether humans are responsible for global warming (and not whether warming is occurring), Muller asserted in the Wall Street Journal that the data proves "why you should not be a skeptic, at least not any longer."
But now that other climatologists have had time to analyze BEST's research, a different picture has emerged. Science editor Dr. David Whitehouse of the Global Warming Policy Foundation (GWPF) charted a new graph based on the raw data from BEST. "It is a statistically perfect straight line of zero gradient," announced Whitehouse. "Could it really be the case that Professor Muller has not looked at the data in an appropriate way to see the last ten years clearly?"
