Science NewsNOAA Unmanned Aircraft Helping Scientists Learn About Alaskan Ice Seals2 June 2009 - NOAA's Fisheries Service scientists and their partners have launched an unmanned aircraft to mount the vehicle’s first search for ice seals at the southern edge of the Bering Sea pack ice during the arctic spring, in an effort to learn more about these remotely located species. {more} United States Arctic Policy - As the U.S. Looks North, Should Canada be Concerned?28 May 2009 - Until recently, the United States has been reluctant to take the initiative in the area of international arctic policy, and has not focused its attention on the region. But that appears about to change. {more} Arctic Methane Rise Spurs Worry on Permafrost Thaw22 May 2009 - A rise in concentrations of a powerful greenhouse gas over the Arctic after a decade of stability is stirring worries about a possible thaw of vast stores trapped in permafrost, experts said. {more} New Plans to Strengthen UK Arctic Research8 May 2009 - A dedicated office to support UK scientific research in the Arctic is being established this week by the Natural Environment Research Council (NERC). {more} Rise of Oxygen Caused Earth's Earliest Ice Age7 May 2009 - Geologists may have uncovered the answer to an age-old question - an ice-age-old question, that is. It appears that Earth's earliest ice ages may have been due to the rise of oxygen in Earth's atmosphere, which consumed atmospheric greenhouse gases and chilled the earth. {more} Arctic CO2 Levels Growing at an Unprecedented Rate, Say Scientists27 April 2009 The concentration of carbon dioxide in the atmosphere has reached a record high, according to the latest figures released by an internationally regarded measuring station in the Arctic. {more} Arctic Meltdown is a Threat to Humanity25 March 2009 - "I am shocked, truly shocked," says Katey Walter, an ecologist at the University of Alaska in Fairbanks. "I was in Siberia a few weeks ago, and I am now just back in from the field in Alaska. The permafrost is melting fast all over the Arctic, lakes are forming everywhere and methane is bubbling up out of them." {more} Arctic Scientists, Hunters Meet to Discuss Harmful Research Methods15 March 2009 - Scientists are to meet with arctic hunters this week to discuss long-simmering concerns that research methods harm northern animals and ignore knowledge that the Inuit have accumulated over generations. {more} UN Scientists: Climate Change Evidence Unequivocal26 February 2009 - Scientists for the United Nations Intergovernmental Panel on Climate Change, or IPCC, say the group's latest findings on global warming show rapidly increasing carbon dioxide emissions and quickly shrinking arctic ice. To compound matters, a separate study released on Wednesday finds that the melting of polar ice is more severe than previously thought. {more} Arctic Ice Satellite Sensor Malfunctions, But Ice Still Retreating25 February 2009 - The U.S. National Snow and Ice Data Center blamed sensor drift for a satellite's failure to detect some 193,000 square miles of arctic sea ice. Scientists are able to use earlier data and correct for the error using another satellite's date, and the error does not contradict reports the sea ice still is shrinking. {more} Arctic Storms Seen Worsening; Threat to Oil, Ships4 February 2009 - Arctic storms could worsen because of global warming in a threat to possible new businesses such as oil and gas exploration, fisheries, or shipping, a study showed on Wednesday. {more} CO2 Piling Up Over Arctic, Scientists Find30 January 2009 - Scientists who flew a modified corporate jet from pole to pole to study how greenhouse gases move, found carbon dioxide piling up over the Arctic, but also higher than expected levels of oxygen over the Antarctic. {more} Bush Supports Ratification of Sea Treaty to Administer Arctic12 January 2009 - In one of its last official acts, the Bush administration released a comprehensive policy Monday for the arctic regions, addressing the growing number of boundary, resource development, and shipping disputes in the fast-changing waters north of Alaska's coast. {more} Ecosystem Changes In Temperate Lakes Linked To Climate Warming27 December 2008 - Unparalleled warming over the last few decades has triggered widespread ecosystem change in many temperate North American and Western European lakes, say researchers at Queen's University and the Ontario Ministry of the Environment. {more} Changes 'Amplify Arctic Warming'17 December 2008 - Scientists say they now have unambiguous evidence that the warming in the Arctic is accelerating. Computer models have long predicted that decreasing sea ice should amplify temperature changes in the northern polar region. {more} Arctic Tundra Emits Methane Even in Winter3 December 2008 - The arctic tundra emits the same amount of methane in winter as in the warmer months, a surprising finding that bolsters understanding of how greenhouse gases interact with nature, researchers said on Wednesday. {more}
