Arctic Literally on Thin Ice07/04/2009 |
| New evidence from satellite observations shows a continuation in the decade-long trend of shrinking Arctic sea-ice cover and a thinning ice cap. The latest data comes from NASA and the National Snow and Ice Data Center. According to scientists tracking Arctic sea-ice cover from space, the maximum extent of ice this winter was the fifth lowest on record. The six lowest maximums since satellite monitoring began in 1979 have all occurred in the past six years (2004-2009). |

Arctic sea ice works like an air conditioner for the global climate system. Ice naturally cools air and water masses, plays a key role in ocean circulation, and reflects solar radiation back into space. In recent years, Arctic sea ice has been declining at a surprising rate.
