(NASA/Goddard Space Flight Center) Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world’s largest non-polar ice masses, according to new research by scientists from NASA and the Chinese Academy of Sciences. Soot absorbs incoming solar radiation and can speed glacial melting when deposited on snow in sufficient quantities. Temperatures […]
(University of Colorado at Boulder) The northern coastline of Alaska midway between Point Barrow and Prudhoe Bay is eroding by up to one-third the length of a football field annually because of a “triple whammy” of declining sea ice, warming seawater and increased wave activity, according to new study led by the University of […]
Rising temperatures and sea levels brought on by climate change could have devastating effects on British wildlife from salmon to wildfowl, the Environment Agency warned.

By John Roach for National Geographic News December 10, 2009 A decade ago, global climate change was largely considered a problem for the distant future. But it seems that future has come sooner than predicted. One of the most remarkable, and alarming, environmental changes to occur over the last decade is the melting of Antarctic […]
The mysterious bird-killing algae that coated Washington’s ocean beaches this fall with slimy foam was the biggest and longest-lasting harmful algal bloom in Northwest history. Now the phenomenon that killed at least 10,000 seabird has scientists consumed by questions: Was it a rogue occurrence, rarely if ever to be repeated, or a sign of some […]
By Tim BradnerAlaska Journal of Commerce Coastal erosion isn’t the only climate-related problem confronting rural communities. Health officials now are concerned about food and water safety in northern villages as warming temperatures thaw ice cellars and melting permafrost increases the organic content in rivers, creating problems in village water treatment plants. As for erosion, it […]
