Abstract: Ice loss and raised sea levels The Canadian Arctic Archipelago contains one-third of the global volume of land ice outside the ice sheets, but its contribution to sea-level change is largely unknown. Gardner et al. use three independent techniques to reveal that mass loss from the archipelago was 92 ±12 gigatonnes per year in 2007–09, about three times greater than in 2004–06, and coincident with warmer summer temperatures. The record is too short to allow a firm conclusion on longer-term trends, but it is clear that the Canadian Arctic Archipelago is a significant contributor to sea-level rise.
