Muller flip-flops again?

Is Richard Muller climatically bipolar?

About Muller’s testimony before a House Committee today, AFP reported:

A prominent climate change skeptic told Congress on Monday he no longer doubts that global warming is real and caused by humans, and joined other scientists in urging action to stop it.

Physicist Richard Muller, director of the Berkeley Earth Surface Temperature Project, whose two-year research was funded in part by a foundation formed by the conservative billionaire Koch brothers, said he could find no bias in other studies.

“We confirm that over the last 50 years, temperature has risen 0.9 degrees Celsius, or 1.6 degrees Fahrenheit. This is the same number that the IPCC (UN Intergovernmental Panel on Climate Change) says.”

But Muller didn’t really say that global warming is caused by humans. The AFP report continues:

Muller told the House Committee on Natural Resources that while he remains cautious about the extent to which humans have played a role, he now hopes other climate skeptics will come on board with his findings.

“As they read and study our papers, I am hoping that many of them will reflect my belief that they are open-minded and come to agree that yes, climate change temperature increase certainly has happened,” he said.

“The amount that is due to humans is still open and there are very big uncertainties in that,” Muller added, urging continued study of the matter.

“In my mind, humans have contributed to climate change. The real issue is how much?”

But every skeptic believes that humans have contributed to climate change — just through land use if nothing else.

The question that’s being blurred by media reports of Muller is whether and to what extent and effect to do manmade greenhouse gas emissions affect climate.

Muller is clueless on all those questions.

  1. I am not sure whether this is obfuscation on the part of Muller or bad reporting as to his actual testimony. Maybe a bit of both?
