FOSSIL PLANTS found beneath MILE DEEP GREENLAND ICE indicating risk of rapid sea level rise

Longlost Camp Century ice core provides direct evidence that giant ice sheet melted off within the last million years and is highly vulnerable to a warming climate, PNAS study shows. In 2019, University of Vermont scientist Andrew Christ looked at it through his microscopeand couldnt believe what he was seeing: twigs and leaves instead of just sand and rock. That suggested that the ice was gone in the recent geologic pastand that a vegetated landscape, perhaps a boreal forest, stood where a miledeep ice sheet as big as Alaska stands today. Over the last year, Christ and an international team of scientistsled by Paul Bierman at UVM, Joerg Schaefer at Columbia University and Dorthe DahlJensen at the University of Copenhagenhave studied these oneofakind fossil plants and sediment from the bottom of Greenland. Their results show that most, or all, of Greenland must have been icefree within the last million years, perhaps even the last fe
