The flow and variability of sea-ice in the Canadian Arctic Archipelago: modelling the past (1950-2004) and the future (2041-2060)
Considering the recent losses observed in Arctic sea-ice and the anticipated future warming due to anthropogenic greenhouse gas emissions, sea-ice retreat in the Canadian Arctic Archipelago (CAA) is expected. As most global climate models do not resolve the CAA region, a fine-resolution regional mod...
