Greenland ice cores tell tales on past sea level changes
Distinguished International Visiting Fellow Lecture
5pm, Wednesday 21st February 2018
Large Lecture Theatre, Department of Geography, Downing Site
All the deep ice cores drilled to the base of the Greenland ice sheet contain ice from the previous warm climate period, 130-115 thousand years before present, demonstrating the resilience of the Greenland ice sheet to a warming of 5°C. Material from the base of the ice cores reveals the presence of boreal forests before the ice covered Greenland, implying that temperatures at that time had been more than 10°C warmer than the present. To compare the paleo-behaviour of the Greenland ice sheet to the present, in relation to sea level rise, the international EGRIP-project is drilling an ice core in the centre of the active North East Greenland Ice Stream (NEGIS). At this lecture, the first results will be presented.
