Permafrost in a Changing Climate: Arctic Lake and Drained Lake Basin Systems
June 15th (Tuesday), 6 p.m., Via Zoom (online) – Open to Public. Presentation: “Permafrost in a changing climate: Arctic lake and drained lake basin systems”, Presented by Andy Parsekian, University of Wyoming.
The Arctic system is undergoing rapid change relative to global averages; Earth’s polar regions are clearly warming faster than any other part of the global climate system. Warmer air temperatures and changes in precipitation patterns effect hydrologic processes and the integrity of permafrost; these changes are expected to continue or amplify in the future. What role do Arctic lakes and drained lake basins play in carbon cycling and hydrology? How will they impact permafrost thaw? And what will the impacts be on the global climate we all share and live within? Dr. Andy Parsekian will take us on a tour of his work in the Alaskan Arctic, what his and his compatriots’ work has begun to reveal, and he will discuss potential global effects.
