Boehner digs himself deeper into the idiot hole

Umm, yes, Mr. Speaker, we actually DO know what's causing climate change.

Quote of ill repute:

“I don’t think there’s any doubt that we’ve had climate change over the last 100 years,” he told USA Today. “What has initiated it, though, has sparked a debate that’s gone on now for the last 10 years.”

 The Ohio Republican continued: “I don’t think we’re any closer to the answer than we were 10 years ago."

 So then the Washington Post editorial board sayeth thusly:

Since the middle of the 20th century, scientists have studied the warming effects of adding large amounts of additional heat-trapping gases to the atmosphere, and they have made great progress since then in describing how and why the world is warming, and how that trend is likely to play out years and decades from now.

It's simple. But it behooves the Republican leadership to act like anti-science climate change skeptics, because that's what their constituents want them to be.   How could they not be that, then?
