Science for Understanding the Impacts of Climate Change
The United States faces the alarming possibility of abrupt climate change in the 21st century. Slight changes in climate may trigger major abrupt ecosystem responses - or "tipping points" - that are not easily reversible. The United States could be threatened by continued glacier and ice-sheet melting, sea-ice retreat, coastal erosion, sea-level rise, insect outbreaks, expanded areas of drought, and increased wildfires. These and other impacts pose clear risks to society in terms of our ability to adapt, especially if we are unprepared. Come learn how the USGS is working with the U.S. Climate Change Science Program to provide the science necessary for understanding current and future climate conditions and developing effective adaptation and mitigation strategies, to help the Nation prepare for an uncertain future.
