Impacts of Recent Climate Change: Current Responses and Future Projections for Wild Ecosystems

Oct 13th, 2008 1h 18m

Observed changes in natural systems, largely over the past century, indicate a clear global climate change signal. Even in the face of apparently dominating forces, such as direct, human-driven habitat destruction and alteration, this climate f
