The secrets of climate change locked in the Greenland ice cores will be revealed tonight when a specialist from the Niels Bohr Institute in Copenhagen discusses the evidence for past climate change events in a lecture at the Royal Irish Academy in Dublin.
Prof Sigfus Johann Johnsen has spent 27 summers studying the Greenland ice sheet and will argue that our climate systems reveal a perennial instability. Ice cores from glaciers and "old" ice carry a record of past climatic and environmental changes, and Prof Johnsen will explain what has been learned so far.
The talk takes place at the RIA, 19 Dawson Street, tonight at 8 p.m.
