ScienceDaily (2009-02-26) -- New evidence of the widespread effects of global warming in the polar regions is emerging. Snow and ice are declining in both polar regions, affecting human livelihoods as well as local plant and animal life in the Arctic, as well as global ocean and atmospheric circulation and sea level. The Greenland and Antarctic ice sheets are losing mass contributing to sea level rise. Warming in the Antarctic is much more widespread than previously thought, and it now appears that the rate of ice loss from Greenland is increasing.
