Linkages Between Arctic Warming and Mid-Latitude Weather Patterns: Summary of a Workshop

The Arctic has been undergoing significant changes in recent years. Average temperatures are rising twice as fast as they are elsewhere in the world. The extent and thickness of sea ice is rapidly declining. Such changes may ...

Opportunities to Use Remote Sensing in Understanding Permafrost and Related Ecological Characteristics: Report of a Workshop

Permafrost is a thermal condition -- its formation, persistence and disappearance are highly dependent on climate. General circulation models predict that, for a doubling of atmospheric concentrations of carbon dioxide, mean annual air temperatures may rise up to several degrees ...

Seasonal-to-Decadal Predictions of Arctic Sea Ice: Challenges and Strategies

Recent well documented reductions in the thickness and extent of Arctic sea ice cover, which can be linked to the warming climate, are affecting the global climate system and are also affecting the global economic system as marine access to ...

Lessons and Legacies of the International Polar Year 2007-2008

International Polar Year 2007-2008 (IPY) was an intense, coordinated field campaign of observations, research, and analysis. It was the largest, most comprehensive campaign ever mounted to explore Earth's polar domains. Legacies and Lessons of the International Polar ...

Future Science Opportunities in Antarctica and the Southern Ocean

Antarctica and the surrounding Southern Ocean remains one of the world's last frontiers. Covering nearly 14 million km² (an area approximately 1.4 times the size of the United States), Antarctica is the coldest, driest, highest, and windiest continent on Earth. ...

Frontiers in Understanding Climate Change and Polar Ecosystems: Summary of a Workshop

The polar regions are experiencing rapid changes in climate. These changes are causing observable ecological impacts of various types and degrees of severity at all ecosystem levels, including society. Even larger changes and more significant impacts are anticipated. As species ...

Scientific Value of Arctic Sea Ice Imagery Derived Products

During the 1990s, a government program brought together environmental scientists and members of the intelligence community to consider how classified assets and data could be applied to further the understanding of environmental change. As part of the Medea program, collection ...

Exploration of Antarctic Subglacial Aquatic Environments: Environmental and Scientific Stewardship

Antarctica is renowned for its extreme cold; yet surprisingly, radar measurements have revealed a vast network of lakes, rivers, and streams several kilometers beneath the Antarctic ice sheet. Sealed from Earth's atmosphere for millions of years, they may provide vital ...
