Landsat Study Reveals Greening Across North America’s Arctic

Analyzing 29 years worth of satellite images (1984-2012), a NASA Goddard Space Flight Center research team found nearly one-third of land cover has been changing to resemble landscapes in warmer ecosystems.

Microbes Could Quickly Unlock Huge Carbon Stores in Arctic Permafrost

A first-of-a-kind study indicates microbial action on thawing Arctic permafrost can result in rapid increases in atmospheric CO2. Extending across northern Eurasia and Alaska, the equivalent of more than twice as much CO2 is stored in Arctic permafrost as is present in the atmosphere, highlighting the risk and threats posed by a warming climate.

Politics of a Warming Arctic

The front line of climate change and the politics of a warming Arctic – It was just a little over 100 years ago that Robert Peary’s expedition first reached the north pole – or at least very close. In 1991 eight “arctic nations” signed the Arctic Environmental Protection Strategy (AEPS), including Canada, the United States, Finland, Iceland, Norway, Sweden, Denmark, and…

NASA to Study Arctic Sea Ice Loss’s Climate Impact Like Never Before

With temperatures in the Arctic rising twice as fast as elsewhere, ARISE will be the first NASA airborne Arctic field campaign equipped to simultaneously measure the balance of of factors that determine climate warming.

Artic Sea Ice and Albedo: Ice Free Season Growing 5 Days per Decade

Arctic ice autumn freeze-up starting later  – According to new research to be published in the forthcoming issue of Geophysical Research Letters, the ice-free season in the Arctic is growing by five days per decade. Analysis of satellite data by a team of researchers headed by Julienne Stroeve indicate increasing absorption of solar energy in the summer Arctic ocean is pushing…

Greenpeace Launches Campaign to Establish an Arctic Sanctuary

Warming twice as fast as the rest of our world, the Arctic region has become a climate change hotspot. Given the profound ramifications for ecosystems and societies across the region and worldwide, the rapid (from an Earth history perspective) warming taking place in the Arctic has scientists, governments, environmentalists and public interest groups concerned, as well as focused on trying…
