Sarah Huckabee Sanders on Tuesday dismissed the dire new climate report.

White House press secretary Sarah Huckabee Sanders said that the recently-released U.S. government climate report draws "radical conclusions" and is not "based on facts."  At Tuesday's press briefing, Sanders was asked if the president feels responsible "to lead…on climate change and preventing the calamity" the administration forecasts.  She replied that the president is "leading on what matters most in this process and that's clean air and clean water."  Sanders continued: "Even Obama's undersecretary for science didn't believe the radical conclusion of the report…and you have to look at the fact that this report is based on the most extreme modeled scenario which contradicts long-established trends."  She also stated that the findings are not "based on facts. It's not data-driven…It's based on modeling, which is extremely hard to do when you're talking about the climate." The report in question reflects the work of 13 federal agencies and warns that if actions to curb the effects of climate change are not taken, its effects will shrink the US economy by 10% before the century ends.  The New York Times notes: "There is always some uncertainty in climate projections, but scientists' estimates about the effects of global warming to date have largely been borne out."
