Greenland Ice Going – Gone? Examining a drill core collected during the Cold War
The mile thick Greenland ice sheet would raise the oceans of the world by 7 meters if all of it melted. Climate change deniers say this massive ice sheet, second only to the Arctic, could never thaw completely – or at a rate that concerns us.
Examining a drill core collected during the Cold War and forgotten for almost 60 years, Andrew Christ and his Vermont Colleague Paul Bierman found evidence of plant life from less than a million years ago. They found frozen under nearly 1.4 km of ice, well-preserved fossil plants and biomolecules sourced from at least two ice-free warm periods in the past few million years.
Andrew Christ was interviewed at the end of March 2021. Thanks to [ . . . ]
