Monday night on "The Colbert Report," Stephen Colbert addressed a serious topic: global climate change, with a serious guest, Harvard environmental scientist David Keith.
As the author of the book, "A Case for Climate Engineering," Keith suggested to Colbert a very simple tactic to combat the steadily warming planet. Have a fleet of planes deposit tons of sulfuric acid into the atmosphere.
"Spray pollution into the atmosphere to stop it warming," Keith said.
"So in the end, pollution saved them all," Colbert said.
"It would be a totally imperfect fix," Keith cautioned. "It would have risks. It wouldn't get us out of the need to stop polluting. But it might actually save people and be useful."
But let's back up a second. Did he actually say sulfuric acid? The stuff that burns the cornea and causes blindness if it comes in contact with your eyes?
