Investigating a Rapid Glacial Retreat | Polar Extremes

Learn what is causing Jakobshavn Glacier in western Greenland to retreat so rapidly, and see how geological processes at the point where a glacier meets the sea can impact glacial retreat, in these videos from NOVA: Polar Extremes and NOVA’s digital series, Antarctic Extremes. Use this resource to help students visualize glacial movement from different perspectives and to exemplify how a change in one Earth system may lead to amplified effects in another system.
