Ice Slabs, Surprise Crevasses, and Cold-War Bases: Explorations of Surface Meltwater from the Interior of the Greenland Ice Sheet

Dr. Mike MacFerrin, Department of Geography, CU Boulder (and spring 2019 GES lecturer)

Abstract:  "Over the past two decades, surface meltwater has rapidly increased over the Greenland ice sheet, enhancing glacial runoff and turning Greenland into the world's largest single source of global sea-level rise. Join CU Boulder's Dr. Mike MacFerrin as he outlines recent findings from field campaigns, remote sensing, and climate modeling about the ways that meltwater is rapidly changing the behavior of Greenland's high-elevation interior, ice that was previously thought to be relatively cold and stable. In addition to meltwater causing a polynomial increase in runoff area and volume coming from Greenland, MacFerrin will outline brand-new findings that may hold implications for the Greenland ice sheet's long-term stability. Acknowledging the complicated intersection of climate and humanity, MacFerrin will present a recent study about the ways that Greenland's runoff is currently re-igniting geo-political tensions that were long thought to be buried in the past."
