Researchers Learning More about How Water beneath Greenland's Glaciers Contributes to Ice Loss

12/16/2009 Scientists who study the melting of Greenland’s glaciers are discovering that water flowing beneath the ice plays a much more complex role than they previously imagined. More

Study: Earth's Polar Ice Sheets Vulnerable to Even Moderate Global Warming

12/16/2009 A new analysis of the geological record of the Earth's sea level employs a novel statistical approach that reveals the polar ice sheets are vulnerable to large-scale melting even under moderate global warming scenarios. More

NSF-funded Study: Antarctica Served as Climatic Refuge 250 Million Years Ago during Earth's Greatest Extinction

12/1/2009 A new fossil species suggests that about 250 million years ago some land animals may have survived the largest known mass extinction in Earth's history--the end-Permian extinction--by living in cooler climates in Antarctica. More

USGS: "North Pole Wolf" E-mails Locations to Researchers and His "Public"

12/1/2009 Thanks to a satellite collar, two innovative scientists, and a blog, people can follow Brutus, the “North Pole wolf”, as he leads his pack through the long arctic winter. Reserachers hope to learn what wolves like Brutus do in the cold and dark. More

NOAA: Significant Ozone Hole Remains Over Antarctica

11/17/2009 The Antarctic ozone hole reached its 2009 peak circumference in late September, according to measurements by NOAA. It This ranked as the 10th largest since satellite measurements began in 1979. More

Ancient Penguin DNA Raises Doubts about Accuracy of Genetic Dating

11/10/2009 Penguins that died 44,000 years ago in Antarctica have provided DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches may underestimate the age of many specimens by 200 to 600 percent. More

109th Airlift Wing Starts Operation Deep Freeze: Planes Depart for Antarctica

10/21/2009 The New York Air National Guard’s 109th Airlift Wing kicked off its 21st year of support for American Antarctic research today, as two ski-equipped C-130s roared off the runway here bound for the South Pole. More

Arctic Sediments Show that 20th-Century Warming is Unlike Natural Variation

10/19/2009 The possibility that climate change might simply be a natural variation like others that have occurred throughout geologic time is dimming, according to a team of reserachers from three U.S. universities. More

USGS: Arctic Now Traps 25 Percent of World’s Carbon--But That Could Change

10/14/2009 The arctic now traps or absorbs up to 25 percent of global carbond dioxide, but climate change could alter that amount significantly, according to a study published in the November issue of Ecological Monographs. More

Arctic Sea-ice Extent Remains Low; 2009 sees Third-lowest Mark Since Records Began in 1979

10/6/2009 Arctic sea ice extent in September was the third lowest since satellite records began in 1979. More ice cover remained this year than during the previous record-setting years of 2007 and 2008. But sea ice has not recovered to previous levels. More
