August 7, 2009 09:19 AM - Yereth Rosen, Reuters

Three major glaciers in Alaska and Washington state have thinned and shrunk dramatically, clear signs of a warming climate, according to a study released Thursday by the U.S. Geological Survey. The three glaciers -- Gulkana and Wolverine in Alaska and South Cascade in Washington -- are considered benchmarks for those in alpine and maritime climates because they closely parallel other glaciers in their regions. They have also been the subject of close scientific scrutiny since 1957.

August 4, 2009 07:10 AM - Roger Greenway, ENN

A major report issued by the United Nations Millenium Project has just been released. It finds that half the world appears vulnerable to social instability and violence due to increasing and potentially prolonged unemployment from the recession as well as several longer-term issues: decreasing water, food, and energy supplies per person; the cumulative effects of climate change; and increasing migrations due to political, environmental, and economic conditions. It also finds some good in the global financial crisis, which may be helping humanity to move from its often selfish, self-centered adolescence to a more globally responsible adulthood.
