The National Oceanic and Atmospheric Administration (NOAA) provides data on future sea level increases as climate change continues. This new tool predicts how rising sea levels could affect the coastline. National Oceanic and Atmospheric Administration (NOAA) National Oceanic and Atmospheric Administration (NOAA)Projections for the year 2100NOAA's Sea Level Rise Viewer provides projections of sea level increases from best- to worst-case scenarios through 2100. By 2100, sea levels in Montauk, New York, are projected to rise between 2.49 feet in the best case and 6.66 feet in the worst case.
