Please join us remotely this Thursday (5/21) at 2:00 pm for the next Polar Seminar! Our speaker will be Dr. Twila Moon from the National Snow and Ice Data Center (NSIDC). She will be presenting a talk entitled "Rapid reconfiguration of the Greenland Ice Sheet under climate change". Please register for the meeting using this Zoom link.
Abstract:
Over the last 30 years, the Greenland Ice Sheet has transitioned from a state of near balance to substantial and sustained ice loss. Greenland is now one of the top contributors to global sea level rise, and the added freshwater to the ocean is also influencing regional ocean properties and circulation and local ecosystems. In this talk, Dr. Twila Moon will explore the now multi-decadal record of rapid ice sheet change, including widespread retreat and more complex responses in velocity and dynamics. She’ll discuss the overlapping processes that are driving increased melt on the ice sheet surface and at the ice-ocean interface, with many of those processes further amplifying the ice sheet response to climate. This rapid reconfiguration of the ice sheet is dramatically changing the Greenland coastal margin and may serve as an important proxy for considering the character of past and future ice sheet loss.
