The mile thick Greenland ice sheet would raise the oceans of the world by 7 feet 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 independent radio producer and friend Alex Smith for allowing me to re-broadcast this interview, first broadcast on his weekly Radio Ecoshock program.
