A Republican Congressman cited the biblical flood as an example of climate change that had not been caused by humans. Texas Rep. Joe Barton made those remarks Wednesday at the Subcommittee on Energy and Power hearing on H.R. 3, the Northern Route Approval Act, a bill that would give Congress the authority approve the Keystone pipeline.

"I don't think it's a secret that I'm a proponent and supporter of the Keystone pipeline," Barton said.

Barton continued to say he didn't deny the climate was changing, but argued that the change was due to natural causes, as he has in the past.

"I would point out that people like me who support hydrocarbon development don't deny that climate is changing," he added. "I think you can have an honest difference of opinion of what's causing that change without automatically being either all in that's all because of mankind or it's all just natural. I think there's a divergence of evidence."

Barton then cited the biblical Great Flood as an example of climate change not caused by man.

"I would point out that if you're a believer in the Bible, one would have to say the Great Flood is an example of climate change and that certainly wasn't because mankind had overdeveloped hydrocarbon energy."
