Please join us for another one of our Climate Sessions Slip Slidin’ Away! Presented by Sridhar Anandakrishnan who is a Professor of Geosciences at Penn State.
Glaciers are an integral part of the global hydrological (water) system. Sea level around the world is affected by the state of the ice sheets of Antarctica and Greenland and glaciers in the Himalayas and Alaska. Glaciers’ size and global sea level are related because water leaves the ocean (as evaporation) and falls on the ice sheet (as snowfall). Then, the water returns to the ocean by glacier flow and eventual melt. Predicting what sea level will be in the future involves understanding a number of interacting processes: air temperature changes; ocean temperature changes; and associated changes in glacier flow speeds. Sridhar will present a non-technical overview of the important issues associated with Polar glaciology. He will include a number of pictures from his own experiences in Antarctica and Greenland.
