Prof Richard Muller had spent two years trying to discover if the mainstream scientists were wrong but concluded they were right. Temperatures are rising and his results, he concluded, “proved you should not be a sceptic, at least not any longer”. Case closed.
But is it? Not according to Prof Judith Curry, a member of Prof Muller’s team, who claims the same findings have shown that global warming has stopped – plunging the rest of us into a quandary of what and who to believe.
When Prof Curry heard that Prof Muller was saying that the Berkeley Earth Surface Temperature (BEST) findings would put an end to climate change scepticism for good she was horrified. “This isn’t the end of scepticism,” she exclaimed.
....
Prof Muller appeared on Radio 4’s Today Programme last Friday where he described how BEST’s findings showed that since the Fifties global temperatures had risen by about 1 degree Celsius, a figure which is in line with estimates from Nasa and the Met Office.
When asked whether the rate had stopped over the last 10 years he said they had not. “We see no evidence of it having slowed down,” he replied and a graph issued by the BEST project suggests a continuing and steep increase.
....
A report published by the Global Warming Foundation, which is based on BEST’s findings, includes a graph of world average temperatures over the past 10 years and it is absolutely flat, suggesting that temperatures have remained constant.
This issue is crucial because the levels of carbon dioxide in the air have continued to rise rapidly over the last decade and if temperatures have remained constant during that period it would suggest there is no direct link between carbon gas emissions and global warming.
....
Prof Muller has made it clear that the BEST study was not conducted in order to gauge the causes of global warming, saying the study “made no assessment on how much of this is due to humans and how much is natural”.
He and his scientists – who also included this year’s physics Nobel winner Saul Perlmutter – set out purely to determine once and for all whether climate change had occurred.
The group had been suspicious of previous results which confirmed a rise in global temperatures , believing that their work may have been skewed by the “urban heat island effect” where increasing urbanisation around weather stations was causing the temperature increases recorded over the past 50 years.
But their exhaustive research discovered that the urban heat effect could not explain the global temperature increase of about one degree Celsius since 1950.
IT IS well to point out that Prof Curry is not disputing the one degree Celsius increase. She is disputing Prof Muller’s suggestion that temperatures haven’t levelled off in the last decade.
....
What she also seems furious about is the way that Prof Muller went about publishing BEST’s results without consulting her and before a proper peer review could be carried out. “It is not how I would have played it,” she has said. “I was informed only when I got a group email. I think they have made errors and I distance myself from what they did. It would have been smart to consult me.”
This is, you can be sure, not the last we will hear on the debate.
