Join us on February 21 from 1:30 p.m. - 3:00 p.m. in Coor 5536 for our latest colloquium.
For this session, we are very excited to welcome Dr. Dan Shugar, associate professor of geoscience and director of the Environmental Sciences Program at the University of Calgary, who will be presenting his talk "What is happening to the world's glacier lakes?"
About the talk:
Glacial lakes are rapidly growing in response to climate change and glacier retreat; some present an acute risk to downstream communities, infrastructure, and ecosystems in the event of an outburst flood. The role of these lakes as terrestrial storage for glacial meltwater is currently unknown and therefore not accounted for in global sea level models. Here, we provide the first global glacier lake database and analysis of glacial lake extent, volume and change. We use scaling relations to estimate an increase of global glacier lake volume of about 48% to 156.5 km3 over the past quarter-century, which represents a sea level equivalent of about 0.43 mm. As glaciers continue to retreat and feed glacial lakes, the implications for natural hazards and water resources are of considerable societal and ecological importance.
