Impacts of Climate Change
Climate variability during the past several thousand years has affected the salinity, temperature, and dissolved oxygen conditions in the Bay.
Sea-level rise (due to climate change) and land subsidence will continue to cause losses and landward migration of tidal wetlands during the coming century.
The USGS is improving a land-use change model to predict the impacts of urban growth throughout the Chesapeake Bay watershed. Read more ...
USGS Evaluates the Potential Impacts of Land and Climate Change
Projecting the effects of land and climate change on Chesapeake Bay resources and communities is essential for planning how to adapt to these future conditions. The projections will help meet the goals and outcomes of the President’s strategy for protecting and restoring the Chesapeake Bay watershed (Executive Order 13508) and for Chesapeake Bay partnership activities. The U.S. Geological Survey (USGS) is working with the National Oceanic and Atmospheric Administration (NOAA) and other partners to better instill an understanding of land and climate change in the planning and modeling of water quality, habitat, fish and wildlife, and land conservation. Some specific activities for the USGS include:
- Assess and forecast changes in streamflow and land cover across the Chesapeake Bay watershed to help assess potential changes in nutrient and sediment loads to the bay.
- Monitor and model sea-level rise along the Atlantic Coast to help assess the impact a sea-level rise will have on coastal wetlands and waterfowl.
- Address the potential impact of land and climate change on brook-trout habitat.
The USGS is working in partnership with federal partners (NOAA, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, U.S. Forest Service) and State and academic partners to address these potential impacts. We are working with regional efforts including Landscape Conservation Cooperatives and U.S. Department of the Interior (DOI) Climate Science Centers to conduct these science activities.
