Nature Climate Change, August 31 The Greenland and Antarctic ice sheets have increased global sea level by 12.3 mm from 2007 and 2017, matching the most pessimistic predictions of the IPCC’s most recent assessment report (AR5). In particular, this study indicated that current models underestimate the contribution of ice sheet surface melt. The comparison […]
Nature, August 20 The Greenland Ice Sheet lost a record-breaking 532 (± 58 Gt) of ice in 2019, up around 200 Gt in the early 2000s, when it first became clear that the ice sheet was losing mass. The two GRACE satellite missions also provided new insights on the sensitivity of the Greenland Ice Sheet to climate-related changes in […]
Nature, Communications Earth & Environment, August 13 Acceleration of outlet glaciers from the Greenland ice sheet, not compensated by accumulation above makes it the current largest contributor to sea level rise. Through the 1980s and 1990s, losses through iceberg calving and melting were replaced by snowfall, keeping the ice sheet in balance. However, starting in […]
Nature, July 29 Over the past 40 years, the rate of change in large portions of the Arctic appears comparable to past rapid warming events, going back to the last interglacial period as reflected in this analysis of Greenland ice cores. These past warming events were typically characterized by warming rates of 1-2°C per decade […]
