Scientists are combining satellite remote sensing and ground survey data to better understand the impacts of
Scientists are gaining new understanding of processes that control greenhouse gas emissions from Arctic
Rapid warming in the Arctic is causing carbon-rich soils known as permafrost, previously frozen for millennia, to thaw. As thawing soils decompose, the...
Scientists are using satellites to collect detailed data on forest change in remote parts of Alaska and the Arctic.
Rapid warming in the Arctic and boreal regions of Alaska is affecting boreal forests and tundra ecosystems in a number of ways. Higher temperatures and changes in precipitation have led to a higher incidence of wildfire and increased tree mortality from
Scientists are using aerial and ground survey methods to measure change in Alaska’s interior forests and its impact on
The boreal forests of interior Alaska are changing rapidly as the climate warms. Wildfires are more frequent and more severe, and declines in growth of spruce trees...

An observing campaign on the West Antarctic Ice Sheet is improving understanding of influences on recent ice loss and the implications for future sea level rise.
Antarctica holds the largest reservoir of ice on Earth and is significant contributor to sea level rise. The West Antarctic Ice Sheet, once considered relatively stable, has shed an increasing amount of ice...
