Sea-level Rise from Greenland Melt May Pose Greatest Threat to Northeast U.S., Canada

5/27/2009 The melting of the Greenland Ice Sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax and other cities in the northeastern United States and Canada.

Arctic Tundra May Contribute to Warmer World

5/27/2009 As the frozen soil in the Arctic thaws, bacteria will break down organic matter, releasing long-stored carbon into the warming atmosphere.

NOAA Opens Public Comment on Potential Arctic Fishing Plan

5/26/2009 NOAA’s Fisheries Service has announced it will open public comment on a proposed framework to manage for the first time fishing in the Arctic waters of the United States in the Chukchi and Beaufort seas.

Polar Bear-Climate Connection Supported by New Study

5/18/2009 Forecasts of polar bear populations and their likely responses to climate change have been strengthened by a new publication. USGS and the U.S. Forest service partially funded the study.

Cold Water Ocean Circulation Doesn't Work as Expected to Moderate Climate

5/13/2009 New research that relied on an armada of sophisticated floats shows that much of the water originating in the sea between Newfoundland and Greenland is diverted generally eastward by the time it flows as far south as Massachusetts.

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.”

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.

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.

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.

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.
