Roundup: How Glaciers Affect and Are Affected By Water

Each week, we highlight three stories from the forefront of glacier news.

Totten Glacier Hurtles Towards Retreat and Possible Collapse

From Nature:

Satellite-based observations indicate that the margin of Totten Glacier may be experiencing greater ice loss than anywhere else in East Antarctica. This, coupled with the presence of low-lying subglacial basins upstream means the Totten Glacier catchment area could be at risk of substantial ice loss under ocean-warming conditions.

Learn more about the processes causing this retreat and the potential sea level rise associated with it.

 

Are Dams the Glaciers of Tomorrow?

From Swiss Federal Institute for Forest, Snow and Landscape Research WSL:

“Water management in reservoirs could substantially mitigate future summer water shortages, expected as a consequence of ongoing glacier retreat, researchers report. The team simulated the effect of climatic change on glaciers across the European Alps and estimated that two thirds of the effect on seasonal water availability could be avoided when storing water in areas becoming ice free.”

Find out how these researchers suggest dealing with glacier retreat and water supplies.

Scientists Present New Research on Tibet’s Climate Risks

From The Columbus Dispatch:

“A consortium of scientists from around the world have gathered in Columbus at Ohio State University’s Byrd Polar and Climate Research Center for the first U.S. meeting about climate issues facing the Tibetan Plateau, a region that includes about 100,000 square kilometers of glaciers that provide drinking water to nearly a third of the Earth’s people.”

Read more about the importance of the Tibetan Plateau and why these scientists feel action is so urgently needed.
