Climate change sceptic admits global warming a fact

Richard Muller looking serious as all good scientists should. His daughter Elizabeth is working hard on the serious look too. A chip off the old block.

A prominent physicist and global warming sceptic spent two years trying to find out if mainstream climate scientists were wrong. In the end, he determined they were right, that temperatures really are rising rapidly.

The study of the world’s surface temperatures by Richard Muller was partially bankrolled by a foundation connected to global warming deniers. He pursued long-held sceptic theories in analysing the data.

He found that the land is 1C warmer than in the 1950s. Those numbers from Muller, who works at the University of California, Berkeley, and Lawrence Berkeley National Lab, match those by the National Oceanic and Atmospheric Administration and Nasa.

Muller said he went even further back, studying readings from Benjamin Franklin and Thomas Jefferson. His finding of a warming world, to be presented at a conference today, is no different from what mainstream climate scientists have said for decades. What’s different is who is behind the study.

One-quarter of the US$600,000 to do the research came from the Charles Koch Foundation, whose founder is a major funder of sceptic groups and the Tea Party movement. The Koch brothers, Charles and David, run a company involved in oil and other industries, producing sizeable greenhouse gas emissions.

Muller’s research team carefully examined two chief criticisms by sceptics. One is that weather stations are unreliable; the other is that cities, which create heat islands, were skewing the temperature analysis.

“The sceptics raised valid points and everybody should have been a sceptic two years ago. And now we have confidence that the temperature rise that had previously been reported had been done without bias.”

Muller said that he came into the study “with a proper scepticism”, something scientists “should always have. I was somewhat bothered by the fact that there was not enough scepticism” before.

There is no reason now to be a sceptic about steadily increasing temperatures, Muller wrote recently in the Wall Street Journal. Muller did not address in his research the cause of global warming. The overwhelming majority of climate scientists say it is man-made from the burning of fossil fuels such as coal and oil.

It makes sense to reduce the carbon dioxide created by fossil fuels, he said. “Greenhouse gases could have a disastrous impact on the world.” He contends that threat is not as proven as the Nobel Prize-winning Intergovernmental Panel on Climate Change says it is.

Today, Muller is taking his results – four separate papers that are not yet published or peer-reviewed, but will be, he says – to a conference in Santa Fe, New Mexico.

Muller’s study found that sceptics’ concerns about poor weather station quality did not skew the results of his analysis because temperature increases rose similarly in reliable and unreliable weather stations. He also found that while there is an urban heat island effect making cities warmer, rural areas are warming, too.
