Yale study: Most polluted ecosystems recoverable
New Haven, Conn.Most polluted or damaged ecosystems worldwide can recover within a lifetime if societies commit to their cleanup or restoration, according to an analysis of 240 independent studies by researchers at the Yale School of Forestry & Environmental Studies. Their findings will appear in ...Study: Future snowmelt in West twice as early as expected; threatens ecosystems and water reserves
WEST LAFAYETTE, Ind. - According to a new study, global warming could lead to larger changes in snowmelt in the western United States than was previously thought, possibly increasing wildfire risk and creating new water management challenges for agriculture, ecosystems and urban populations.

(Washington, D.C. June 20, 2008) The U.S. Environmental Protection Agency has released a report that can help reduce the potential impact of climate change on estuaries, forests, wetlands, coral reefs, and other sensitive ecosystems.
