The Coastal Flood Exposure Mapper supports users undertaking a community-based approach to assessing coastal hazard risks and vulnerabilities by providing maps that show people, places, and natural resources exposed to coastal flooding. This spatial visualization tool shows maps of people, places, and natural resources exposed to coastal flood hazards including FEMA flood zones, shallow coastal flooding, sea level rise, storm surge.
This online, self-guided resource shows spatial analysts how to incorporate green infrastructure into their GIS work to prioritize areas that will help reduce hazard and climate impacts.
Rising temperatures, changing precipitation patterns and shifts in vegetation communities are changing the effective range and distribution of many native and agricultural species. These habitat shifts impact species and ecosystems.
Climate is an important environmental influence on ecosystems. Warming is likely to force some species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival. Similarly, as sea level rises, saltwater intrusion into a freshwater system may force some key species to relocate or die, thus removing predators or prey that were critical in the existing food chain. Negative impacts to species and habitats have already been observed.
Grasslands cover approximately 400 million acres of the contiguous United States.Despite their extensive distribution, grasslands and the neighboring deserts that make up more arid regions are sensitive ecosystems that can be vulnerable to extreme changes in temperature and shifts in precipitation. Land trusts are working to manage grasslands for climate change to protect the biodiversity, habitats, and ecosystem services these landscapes provide.
Climate change has already been linked to changes in wildlife distribution, reproduction and behavior. Enhancing connectivity and “conserving the stage” are critical conservation objectives that can help species adapt to changing conditions.
NOAA’s Sea Level Rise and Coastal Flooding Impacts Viewer allows users to view several sea level rise scenarios and associated impacts to coastal wetlands, which can help land trusts prioritize areas for conservation. The viewer is available for all coastal states and territories except for Alaska.
Modern climate change differs from natural climate change — also known as geologic climate change — because it is caused by humans and is occurring much faster than geologic climate change. Modern climate change is primarily driven by the effects of greenhouse gases, and is directly linked with human activities.
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.
