GIS Analysis of Global Impacts from Sea Level Rise

Future sea level rise caused by climate change would disrupt the physical processes, economic activities, and social systems in coastal regions. Based on a hypothetical global sea level increase of one to six meters, we developed GIS methods to assess and visualize the global impacts of potential inundation using the best available global datasets. After susceptible areas were delineated, we estimated that the size of the areas is between 1.055 (one meter) to 2.193 million km2 (six meters). Population in the susceptible areas was estimated to range from 108 (one meter) to 431 million (six meters) people. Among the seven land-cover types in the susceptible areas, forest and grassland account for more than 60 percent for all the increments of sea level rise. A suite of interactive visualization products was also developed to understand and communicate the ramifications of potential sea level rise.
