Science and Impacts

Climate change, global warming, the greenhouse effect--what do these terms mean, and how can we begin to understand it all? In the presentation that follows, SafeClimate explains the basics of climate science and explores the potential impacts of climate change, including significant changes to many ecosystems, effects on human health, threatened fresh water sources, and more. The impacts presented are based on key conclusions of a peer-reviewed report by the U.S. Global Change Research Program that describes in detail the expected impact of climate change on different ecosystems and regions of North America.
