Barmy denialist or just sacasm?

This is the kind of republican that … makes me proud to be British … or perhaps I just don’t understand his humour?

But if it were true — and most of the world’s scientists agree it is — Rohrabacher said he’s hit on an answer by tackling the 80 to 90 percent of heat-trapping greenhouse gas emissions “generated by nature itself”: Namely, yank down old trees and get rid of the rotting wood in rainforests.
“Is there some thought being given to subsidizing the clearing of rainforests in order for some countries to eliminate that production of greenhouse gases?” the California Republican asked Todd Stern, the top U.S. climate diplomat and lead witness at the hearing. “Or would people be supportive of cutting down older trees in order to plant younger trees as a means to prevent this disaster from happening?”
Stern promised to deliver a technical expert from the State Department to get at the heart of Rohrabacher’s questions. But he also tried to correct the record by pointing out that the focus of global warming policy actually centers on keeping the world’s trees standing, especially in places like the Amazon, Congo and Indonesia.
He didn’t bite on the merits of Rohrabacher’s argument that trees cause global warming, which was reminiscent of Ronald Reagan’s much-lampooned statement that trees cause pollution.  (Source politico)
