Online Deniers Falsely Used NASA Study About Antarctic Melt

No, NASA Antarctica study didn’t discredit climate change science

“…[An online news headline referenced a real study by NASA but falsely suggested] the study debunks climate change advocates. A NASA scientist involved in the study…[said] the headline is inaccurate…[The study found] a geothermal heat source called a mantle plume lies deep below Antarctic Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet…The heat source isn’t new or increasing, but may help explain why the ice sheet collapsed so rapidly in an earlier area of climate change and remains unstable…[But the] NASA study is about the bottom of the ice sheet. Climate change has had an impact on the top of the ice sheet. Warmer ocean waters intruding on the ice shelf causes the ice shelves to break up. When grounded ice sheets exit the land and go into the water that causes sea level rise…[The researchers say nothing] in the study has anything to do with climate change…We rate [the online news story’s] claim False.” click here for more
