TAKING INHOFE TO TASK…. As part of his long-time crusade to label global warming a “myth,” Sen. James Inhofe (R-Okla.), arguably the Senate’s most unhinged member, has released yet another “report” to bolster his arguments.

About a year ago, Inhofe released a similar document, pointing to 400 “scientists” who, he said, rejected the scientific consensus on climate change. Now, he claims 650 “scientists” in his latest contribution to the subject.

Amanda Terkel highlights a very good interview from yesterday, in which MSNBC’s David Shuster pressed Inhofe on some of the experts the senator relied on for his report. Among the 650 are economists, engineers, geographers, TV weathermen, and physicists, none of whom have a background in climate science. What’s more, Shuster noted that when digging a little deeper, some of the experts Inhofe cites actually believe that human activity and CO2 emissions contribute to the climate problem.

Making matters worse, some of the scientists included on Inhofe’s list demanded that their names be removed — and Inhofe ignored their requests.

It’s not as if Inhofe was an especially credible character before. With each new embarrassment, he manages to look a little worse.
