Reactions
Given project leader Muller's well-publicised concerns regarding of the quality of climate change research, other critics anticipated that the BEST study would be a vindication of their stance. For example when the study team was announced, blogger Anthony Watts, who popularized several of the issues addressed by the Berkeley Earth group study, stated[15]
"I'm prepared to accept whatever result they produce, even if it proves my premise wrong. The method isn't the madness that weÂ’ve seen from NOAA, NCDC, GISS, and CRU. That lack of strings attached to funding, plus the broad mix of people involved especially those who have previous experience in handling large data sets gives me greater confidence in the result being closer to a bona fide ground truth than anything weÂ’ve seen yet."
When the initial results were released, and found to support the existing consensus, the study was widely decried. Watts spoke to the New York Times, which wrote: "Mr. Watts ... contended that the study's methodology was flawed because it examined data over a 60-year period instead of the 30-year-one that was the basis for his research and some other peer-reviewed studies. He also noted that the report had not yet been peer-reviewed and cited spelling errors as proof of sloppiness."[16] Steven Mosher, a co-author of a book critical of climate scientists, also disapproved saying that the study still lacked transparency. He said: "I'm not happy until the code is released and released in a language that people can use freely."[16] (The code and dataset are available from the BEST Dataset web page.) Stephen McIntyre, editor of Climate Audit, a blog devoted to the analysis and discussion of climate data, said that "the team deserves credit for going back to the primary data and doing the work" and even though he had not had an opportunity to read the papers in detail, he questioned the analyses of urban heating and weather station quality.[14][17]
By constrast, the study was well-received by Muller's peers in climate science research. James Hansen, a leading climate scientist and head of NASA Goddard Institute for Space Studies commented that he had not read the research papers but was glad Muller was looking at the issue. He said "It should help inform those who have honest scepticism about global warming."[10] Phil Jones the director of the Climatic Research Unit (CRU) at the University of East Anglia (UEA), said: "I look forward to reading the finalised paper once it has been reviewed and published. These initial findings are very encouraging and echo our own results and our conclusion that the impact of urban heat islands on the overall global temperature is minimal."[10] Michael Mann, director of the Earth System Science Center at Pennsylvania State University, commented that "...they get the same result that everyone else has gotten," and "that said, I think it's at least useful to see that even a critic like Muller, when he takes an honest look, finds that climate science is robust."[17] Peter Thorne, from the Cooperative Institute for Climate and Satellites in North Carolina and chair of the International Surface Temperature Initiative, said: "This takes a very distinct approach to the problem and comes up with the same answer, and that builds confidence that pre-existing estimates are in the right ballpark. There is very substantial value in having multiple groups looking at the same problem in different ways." [10] A scientist writing at RealClimate.org noted that it was unsurprising that BEST's results matched previous results so well. "Any of various simple statistical analyses of the freely available data ...show... that it was very very unlikely that the results would change," they wrote.[18]
