NASA: Climate Change and Atmospheric Circulation Will Make for Uneven Ozone Recovery

4/9/2009 Earth's ozone layer should eventually recover from the unintended destruction brought on by ozone-depleting chemicals in the 20th century. But new research suggests that greenhouse gases will make the layer quite different. More

Aerosols, Not Greenhouse Gases, May Drive a Significant Portion of Arctic Warming

4/8/2009 New NASA research suggests that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles called aerosols, emitted by both artificial and natural sources. More

New Satellite Data shows Arctic Literally on Thin Ice

4/6/2009 The latest data from NASA and the University of Colorado at Boulder's National Snow and Ice Data Center show the continuation of a decade-long trend of shrinking sea ice extent in the Arctic, including new evidence for thinning ice as well. More

NOAA-funded Research: Ice-free Arctic Ocean Possible in 30 years, not 90 as Previously Estimated

4/2/2009 A nearly ice-free Arctic Ocean in the summer may happen three times sooner than scientists have estimated, according to researchers at the University of Washington. More

USGS: Erosion Doubles Along Part of Alaska’s Arctic Coast: Cultural and Historical Sites Lost

3/16/2009 Coastal erosion has more than doubled in Alaska - up to 45 feet per year - in a 5-year period between 2002 and 2007 along a 40-mile stretch of the Beaufort Sea. More

Climate-related Changes on the Antarctic Peninsula Being Driven from the Top and the Bottom of the Ecosystem

3/16/2009 The Antarctic Peninsula is one of the most rapidly warming spots on Earth. Now, new research indicates that the changing climate is affecting not just the penguins at the apex of the food chain, but the microscopic life that is the base. More

Wind Shifts May Stir Carbon Dioxide From Antarctic Depths

3/12/2009 Natural releases of carbon dioxide from the Southern Ocean due to shifting wind patterns could have amplified global warming at the end of the last ice age--and could be repeated as manmade warming proceeds, a paper in Science suggests More

World Meteorological Organization and the International Council for Science Release IPY Capstone Document

2/25/2009 IPY has yielded new scientific insights into climate change, as well new knowledge about pollutant transport, species’ evolution, and storm formation, among many other areas, the report states. More

NASA: 2008 was Earth's Coolest Year since 2000

2/23/2009 Climatologists at the NASA Goddard Institute for Space Studies have found that 2008 was the coolest year since 2000. The analysis also showed that 2008 is the ninth warmest year since continuous instrumental records were started in 1880. More

Warming Threatens Antarctic Sea Life

2/9/2009 Climate change is about to cause a major upheaval in the shallow marine waters of Antarctica. Predatory crabs are poised to return to warming Antarctic waters and disrupt the primeval marine communities. More
