Coastal Risk Screening Tool

Created: 11/01/2019 - Updated: 3/13/2020


The Coastal Risk Screening Tool enables users to explore sea level rise and coastal flood risk over time, for anywhere in the world, and under multiple pollution scenarios. The maps allow users to choose between leading sea level rise models and to incorporate the most accurate elevation data available—including Climate Central’s new CoastalDEM® elevation data for areas outside the United States.

Climate Central sea-level maps are based on peer-reviewed science in leading journals. These maps should be regarded as screening tools to identify places that may require deeper investigation of risk. Big datasets always include error. Outside of the United States, maps are based on global-scale datasets for elevation, tides, and coastal flood likelihoods. Inside the U.S., more accurate but still imperfect data are used.

UPDATE: March 12, 2020

This new platform for maps depicting sea level rise and coastal flood risk provides even more of the scientifically rigorous information that Climate Central is known for in a new, sleek, and easy-to-use interface. In addition, this new platform will enable Climate Central to create custom maps tailored to various interests and illustrating diverse stories. The first maps released will allow users to explore sea level rise and coastal flood risk by year, water level, and elevation data source. 




Climate Central is an independent nonprofit organization that was founded in 2008 to meet the need for a central authoritative source for climate change information.

Climate Central scientists publish peer-reviewed research on climate science; energy; impacts such as sea level rise; climate attribution and more. But our work isn't confined to scientific journals. We investigate and synthesize weather and climate data and science to equip local communities and media with the tools they need to visualize the threat of climate change and the need for practical solutions.
