Exxon knew about—and planned for—global warming 25 years ago, even as it was telling anyone who asked that the science wasn't there yet. This, anyway, is the conclusion the LA Times has drawn from a review of thousands of the oil giant's archived internal documents. Exxon scientists knew that warming Arctic seas would make it a little easier to drill there, the documents reveal—even though the same climate trends would result in worse storms, bigger waves, and melting permafrost. "We considered climate change in a number of operational and planning issues," Brian Flannery, who was Exxon's in-house climate science adviser from 1980 to 2011, told the reporters. At the time he thought the science was uncertain; still, his projections were, in the reporters' words, "spot-on."
