An environmental group is trying to silence Charles Krauthammer.

The group petitioned the Washington Post in an effort to stop them from running his column on global warming.

In the op-ed, entitled “The myth of ‘settled silence,’” Charles Krauthammer said he was objecting to President Barack Obama’s State of the Union remark that global warming is settled science.

“There is no such thing as settled science, particularly with something as unsettled and as reliant on models – which are very changeable – as is climate studies,” Krauthammer told Bill O’Reilly tonight.

Krauthammer said that Obama blamed climate change for the California drought, although global warming models say that climate change would bring increased rain.

“I’m not a global warming denier, I’m not a global warming believer, I’m a skeptic, I’m open to empirical evidence,” he said.

O’Reilly and Krauthammer also discussed Sandra Korn’s “Harvard Crimson” article, which called for giving up academic freedom in favor of justice.

Krauthammer called Korn’s article “comical” because he said it was terrible writing. He added, “I wouldn’t have given it a C in a high school class.”
