We’re currently experiencing the worst drought in 60 years, a siege of wildfires, and the hottest temperatures since records were kept. But to Republicans in Congress, it’s all a big hoax. The chairman of a subcommittee that oversees issues related to climate change, Representative John Shimkus of Illinois is — you guessed it — a climate-change denier.

At a 2009 hearing, Shimkus said not to worry about a fatally dyspeptic planet: the biblical signs have yet to properly align. “The earth will end only when God declares it to be over,” he said, and then he went on to quote Genesis at some length. It’s worth repeating: This guy is the chairman.

On the same committee is an oil-company tool and 27-year veteran of Congress, Representative Joe L. Barton of Texas. You may remember Barton as the politician who apologized to the head of BP in 2010 after the government dared to insist that the company pay for those whose livelihoods were ruined by the gulf oil spill.

Barton cited the Almighty in questioning energy from wind turbines. Careful, he warned, “wind is God’s way of balancing heat.” Clean energy, he said, “would slow the winds down” and thus could make it hotter. You never know.

“You can’t regulate God!” Barton barked at the House speaker, Nancy Pelosi, in the midst of discussion on measures to curb global warming.
