Loss of sea ice is associated with permafrost thaw in Earth’s past, likely in part due to damaging wave action. This side event explores that connection, and looks at projections should temperature rise continue. The main presenters include Dr. Gustaf Hugelius, Co-Director of the Bolin Center of Climate Research/Stockholm University; and Robbie Mallet, a Cryosphere Pavilion Early Career Scientist volunteer and doctoral student with Dr. Julienne Stroeve at University College London.
