Speaking at a hearing on a the Keystone XL pipeline, which he supports, Rep. Joe Barton (R-TX) acknowledged that climate change is underway. Barton argued, however, that the change is not necessarily man-made. He cited the biblical Great Flood as an example of climate change unrelated to human activities:
"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."
