Here are key excerpts from the Executive Summary of the U.S. Global Change Research Program Climate Science Special Report.1 This is the final 669-page draft report on climate change prepared by scientists from thirteen federal science agencies2 that was in the news in August when it was released unofficially (leaked to The New York Times) because of fears that the Trump administration might suppress it. The report is part of the National Climate Assessment, congressionally mandated every four years. The graphics shown here are from the report.
