Positive mass balance during the late 20th century on Austfonna, Svalbard, revealed using satellite radar interferometry
Determining whether increasing temperature or precipitation will dominate the cryospheric response to climate change is key to forecasting future sea-level rise. The volume of ice contained in the ice caps and glaciers of the Arctic archipelago of Svalbard is small compared with that of the Greenland or Antarctic ice sheets, but is likely to be affected much more rapidly in the short term by cl...

متن کاملSurface mass-balance changes of the Greenland ice sheet
Mass loss from the Greenland ice sheet over the past decade has caused the impression that the ice sheet has been behaving anomalously to the warming of the 1990s. We have reconstructed the recent (1866–2005) surface mass-balance (SMB) history of the Greenland ice sheet on a 5 5 km grid using a runoff-retention model based on the positive degree-day method. The model is forced with new datasets...
متن کاملChanges in ice dynamics and mass balance of the Antarctic ice sheet.
The concept that the Antarctic ice sheet changes with eternal slowness has been challenged by recent observations from satellites. Pronounced regional warming in the Antarctic Peninsula triggered ice shelf collapse, which led to a 10-fold increase in glacier flow and rapid ice sheet retreat. This chain of events illustrated the vulnerability of ice shelves to climate warming and their buffering...
متن کاملApplication of Aircraft Laser Altimetry to Glacier and Ice Cap Mass Balance Studies
The Arctic ice caps and glaciers serve as important indicators of climate change and also make a small, but significant, contribution to changes in global sea level. Consequently, understanding their mass balance is of considerable interest. We are examining the current state of mass balance of the major Canadian ice caps in the greater Baffin Bay area in the context of recent climate condition...
