Global Warming Study Claims There IS Warming….Or Does It? Co-Author Refutes Conclusion

It was hailed as the scientific study that ended the global warming debate once and for all – the research that, in the words of its director, ‘proved you should not be a sceptic, at least not any longer’.

Professor Richard Muller, of Berkeley University in California, and his colleagues from the Berkeley Earth Surface Temperatures project team (BEST) claimed to have shown that the planet has warmed by almost a degree centigrade since 1950 and is warming continually.

Published last week ahead of a major United Nations climate summit in Durban, South Africa, next month, their work was cited around the world as irrefutable evidence that only the most stringent measures to reduce carbon dioxide emissions can save civilisation as we know it.

It was cited uncritically by, among others, reporters and commentators from the BBC, The Independent, The Guardian, The Economist and numerous media outlets in America.

The Washington Post said the BEST study had ‘settled the climate change debate’ and showed that anyone who remained a sceptic was committing a ‘cynical fraud’.

But today The Mail on Sunday can reveal that a leading member of Prof Muller’s team has accused him of trying to mislead the public by hiding the fact that BEST’s research shows global warming has stopped.

Prof Judith Curry, who chairs the Department of Earth and Atmospheric Sciences at America’s prestigious Georgia Institute of Technology, said that Prof Muller’s claim that he has proven global warming sceptics wrong was also a ‘huge mistake’, with no scientific basis.

…She said this affair had to be compared to the notorious ‘Climategate’ scandal two years ago.

Like the scientists exposed then by leaked emails from East Anglia University’s Climatic Research Unit, her colleagues from the BEST project seem to be trying to ‘hide the decline’ in rates of global warming.

In fact, Prof Curry said, the project’s research data show there has been no increase in world temperatures since the end of the Nineties – a fact confirmed by a new analysis that The Mail on Sunday has obtained.

‘There is no scientific basis for saying that warming hasn’t stopped,’ she said. ‘To say that there is detracts from the credibility of the data, which is very unfortunate.’

Of course the BEST group put out a graph that hid the fact that warming has stopped:

Stopped in the face of ever increasing evvvvvviiiiiil CO2.

…‘Of course this isn’t the end of scepticism,’ she said. ‘To say that is the biggest mistake he [Prof Muller] has made. When I saw he was saying that I just thought, “Oh my God”.’

In fact, she added, in the wake of the unexpected global warming standstill, many climate scientists who had previously rejected sceptics’ arguments were now taking them much more seriously.

They were finally addressing questions such as the influence of clouds, natural temperature cycles and solar radiation – as they should have done, she said, a long time ago.

Yesterday Prof Muller insisted that neither his claims that there has not been a standstill, nor the graph, were misleading because the project had made its raw data available on its  website, enabling others to draw their own graphs.

However, he admitted it was true that the BEST data suggested that world temperatures have not risen for about 13 years. But in his view, this might not be ‘statistically significant’,  although, he added, it was equally  possible that it was – a statement which left other scientists mystified.

‘I am baffled as to what he’s trying to do,’ Prof Curry said.

What he is trying to do is to form the debate. Just as Prof. Hanson before him tried to do. Any claim that “the debate is over” should immediately ring alarm bells. Hell, Muller didn’t even consult the co-author on all four papers, Prof Curry, before deciding to release them to the internet instead of allowing the peer review process to carry itself out.

‘For the Berkeley team to have chosen this particular moment to launch a major international publicity blitz is a highly unethical sabotage of the peer review  process.’

In Prof Curry’s view, two of the papers were not ready to be published, in part because they did not properly address the arguments of climate sceptics.

As for the graph disseminated to the media, she said: ‘This is “hide the decline” stuff. Our data show the pause, just as the other sets of data do. Muller is hiding the decline.

And playing the media like a fiddle. He claimed to be a “skeptic” but there is little evidence that he was one. He claimed he just wanted to get the information out there to the climate community, but picked and choose certain reporters and certain papers to interview him. He is trying to form the debate, and now that the climate community has had some time to study their findings his attempt to hide the decline is becoming that much more apparent.

…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?

Indeed Best seems to have worked hard to obscure it. They present data covering more almost 200 years is presented with a short x-axis and a stretched y-axis to accentuate the increase. The data is then smoothed using a ten year average which is ideally suited to removing the past five years of the past decade and mix the earlier standstill years with years when there was an increase. This is an ideal formula for suppressing the past decade’s data.

When examined more objectively Best data confirms the global temperature standstill of the past decade. That the standstill should be present in land only data is remarkable. There have been standstills in land temperature before, but the significance of the past decade is that it is in the era of mankind’s postulated influence on climate through greenhouse gas forcing. Predictions made many times in the past few years suggest that warming should be the strongest and fastest in the land data.

Nice try Muller, but no cigar.
