The Arctic and Antarctic regions are integral components of the Earth's climate system. It has been long believed that changes to Earth's climate will be first seen at the ends of the earth, particularly the Arctic. In that region, recent reports confirm the continuing retreat of glaciers as well as the thinning of sea ice. In Antarctica, the last decade has seen significant calving of icebergs. Earth-observing spacecraft provide an excellent means of monitoring ice in the polar regions. At JPL, researchers are carefully examining both the Arctic and Antarctic, using a broad range of satellite data. This presentation will include an overview of the roles of the polar regions in the our climate system, followed by a discussion of current findings about the dynamic nature of polar ice covers.
