Climate Change in the Polar Regions: Not Waiting for ‘The Day After Tomorrow’ Both poles of the Earth are changing — rapidly and dramatically — in response to greenhouse gas -driven global warming. Yet the polar regions remain spectacular landscapes, wrought of rock and ice and water by geologic processes most of us have never seen. We will review the satellite evidence for recent changes in Arctic sea ice, Greenland’s ice sheet, and coastal Antarctica, and go closer, using pictures from field expeditions to get a more personal sense of these far-off, yet hugely important, regions. Dr. Ted Scambos is the Lead Scientist at the National Snow and Ice Data Center (NSIDC), and a frequent traveller to the Antarctic for research. He uses satellite data, and field instrumentation, to study the polar region’s responses to climate change.
