A Capstone of NSF-supported International Polar Year Deployments, AGAP Project May Help Determine What Caused Ice Sheet to Form Flying twin-engine light aircraft the equivalent of several trips around the globe and establishing a network of seismic instruments across an area the size of Texas, a US-led international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under more than four kilometers (2.5 miles) of ice. ...

February 24, 2009 — The International Polar Year provides a unique opportunity to assess the global State and Fate of Permafrost on a Warming Planet. Recent observations indicate a warming of permafrost in many northern and mountain regions with resulting degradation of ice-rich and carbon-rich permafrost. Permafrost temperature has increased by 1 to 2°C in northern Russia during the last 30 to 35 years. This observed increase is very similar to what has been observed in Alaska where the detailed characteristic of the warming varies between locations, but is typically from 0.5 to 2°C. The last 30-years warming in permafrost temperatures observed in the Russian North and Alaska has resulted in thawing of natural, undisturbed permafrost in areas close to the southern boundary of t...

In the Arctic, climate change is more than just a topic of conversation: it’s a fact of life. Arctic communities have already begun to feel the impacts of climate change, both large and small. Land erosion, melting permafrost, and flooding are forcing several Alaskan villages to consider relocation. The Arctic, like most other parts of the world, has warmed substantially over last few decades. This warming trend is projected to continue, and may lead to significant economic and cultural upheaval particularly for the indigenous peoples of the Arctic. It is anticipated that Arctic communities will be disproportio...
