Sea levels are rising. Recent housing growth rates are faster in ten-year flood-risk zones in a third of all coastal states. Climate Central and Zillow publish updated projections of possible impacts in coastal areas in this updated 2019 report.
In New York, Scenic Hudson is conserving land in 82 communities in ten counties along the Hudson River to buffer against future sea level rise impacts. By targeting key properties for acquisition efforts, this land trust is working to ensure that natural processes such as marsh migration can continue to provide valuable ecological services as well as mitigate the effects of rising waters throughout the estuary.
Hurricane strength is influenced by sea surface temperature. As sea surface temperatures rise the number of intense hurricanes is also expected to increase.
The ESF has been responding to potential climate change impacts by working cooperatively to study and address salt marsh loss. In addition to working with agencies and regional research facilities, ESF conservation projects such as constructing water control structures to adapt to rising sea levels and acquisition and management efforts to “clear the floodplain” address climate change challenges by allowing for migration of tidal marshes and building ecological resilience.
This report, the Potential Consequences of Climate Variability and Change: Coastal offers a comprehensive review of potential impacts to coastal systems due to climate change.
NPR’s recently published After the Water tells a compelling tale of how one community is working to cope with flash floods exacerbated by climate change.
The U.S. Interagency Elevation Inventory provides a comprehensive listing of known high-accuracy topographic and bathymetric data for the U.S. and its territories. Elevation data is necessary to develop coastal elevation models and are critical components when looking at sea level rise, coastal flooding, beach nourishment, erosion, or any other processes that occur within the land-water interface.
Land trusts and conservation groups across the country are using geospatial techniques such as mapping and modeling to identify and reduce vulnerabilities to climate change impacts.
