Increasingly Precise Data on Radiation Reflected from the Arctic Sea Area
October 6, 2011 — Scientists have developed a new, globally unique method for estimating surface albedo in the Arctic sea area solely on the basis of microwave data. Its advantage over conventional optical methods is ... > full story -
Why Climate Models Underestimated Arctic Sea Ice Retreat: No Arctic Sea Ice in Summer by End of Century?
October 6, 2011 — In recent decades, Arctic sea ice has suffered a dramatic decline that exceeds climate model predictions. The unexpected rate of ice shrinkage has now been explained. Researchers argue that climate ... > full story -
Arctic Sea Ice Continues Decline, Hits Second-Lowest Level
October 4, 2011 — Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record. Satellite data from NASA and the the National Snow and Ice Data Center showed that the ... > full story -
Polar Oceans in Transition
October 4, 2011 — Polar bears will be affected by climate change in the Arctic and Antarctic, but so will India's iconic tigers and elephants. Researchers are working to understand what is happening in polar oceans -- ... > full story -
Unprecedented Arctic Ozone Loss Last Winter
October 3, 2011 — A NASA-led study has documented an unprecedented depletion of Earth's protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low ... > full storyMore: -
Model Provides Successful Seasonal Forecast for the Fate of Arctic Sea Ice
September 22, 2011 — Relatively accurate predictions for summer sea ice extent in the Arctic can be made the previous autumn, but forecasting more than five years into the future requires understanding of the impact of ... > full story -
Arctic Sea Ice Nears Minimum Extent
September 14, 2011 — In the last few days, the decline in Arctic sea ice extent has slowed. New data show Arctic sea ice extent currently at the second-lowest levels in the satellite ... > full storyMore: -
Permafrost Could Release Vast Amounts of Carbon and Accelerate Climate Change by End of Century
August 23, 2011 — Billions of tons of carbon trapped in permafrost may be released into the atmosphere by the end of this century as the Earth's climate changes, further accelerating global warming, a new computer ... > full story -
Research Vessel Polarstern at North Pole
August 23, 2011 — On Aug. 22, 2011, the research icebreaker Polarstern reached the North Pole. The aim of the current expedition is to document changes in the far north. The researchers on board are conducting an ... > full story -
Polar Ice Caps Can Recover from Warmer Climate-Induced Melting, Study Shows
August 17, 2011 — New research indicates that even if Earth warmed enough to melt all polar sea ice, the ice could recover if the planet cooled ... > full story -
Polar Climate Change May Lead to Ecological Change
August 11, 2011 — Ice and frozen ground at the North and South Poles are affected by climate change induced warming, but the consequences of thawing at each pole differ due to the geography and geology, according to a ... > full story -
Arctic Ice Melt Could Pause for Several Years, Then Resume Again
August 11, 2011 — Although Arctic sea ice appears fated to melt as the climate continues to warm, the ice may temporarily stabilize or somewhat expand at times over the next few decades, new research ... > full story
