Glacier loss and the climate change crisis: Evidence from Patagonia and the last glacial maximum
The Centre for Crisis Studies and Mitigation at The University of Manchester invites you for a virtual session.
Globally, mountain glaciers are shrinking and receding, resulting in changing meltwater availability for downstream populations, increased hazards such as outburst floods, rockfalls, and glacier detachments and surges. Climate change is also driving an increase in melt from Antarctica and Greenland, driving up sea level rise. In West Antarctica and Patagonia, these changes in melt are related to changes in the Southern Westerly Winds and the Southern Annular Mode (SAM). However, we need a longer term context of glacier change to understand drivers of glacier mass balance and ice sheet change, to contextualise present-day change, and to test and train numerical models. In Patagonia, the long latitudinal transect of the Andean mountain chain provides an ideal natural laboratory to understand changes in the Southern Westerly Winds and the Southern Annular Mode, since these glaciers are very sensitive to these moisture-bearing winds. Here, we present PATICE, a database of Patagonian glacial geomorphology and recalibrated chronostratigraphic data.
The talk will be followed by moderated Q&A via Zoom Chat.
The talk will also be livestreamed and a recording will be available after the event.
