NSF-funded Study Rules Out Ancient Bursts of Seafloor Methane Emissions, has Important Implications for Modern-day Climate Trends

4/24/2009 Measurements made from the largest Greenland ice sample ever analyzed have confirmed that an unusual rise in atmospheric methane levels about 12,000 years ago was not the result of a catastrophic release of seafloor “hydrate deposits.” More

Decline in Greenhouse Gas Emissions Would Reduce Sea-Level Rise, Save Arctic Sea Ice

4/14/2009 If nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, global temperatures would still rise, but the some aspects of climate change, including massive losses of Arctic sea ice and permafrost could be partly avoided. More

University of New Hampshire Scientists Part of Team that Deployed Unmanned Antarctic Observatories to Watch Space Weather

4/10/2009 An international consortium of scientists has successfully developed a series of autonomous observatories in Antarctica that provide critical year-round "space weather" data from the Earth's harshest environment for the first time. More

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
