New Paper Projects Higher Sea Level Rise

new study published in Earth’s Future draws on recent Antarctic ice sheet modeling to make a central projection of roughly 5 feet (1.5 meters) of global mean sea level rise this century – close to doubling the most recent projections from the Intergovernmental Panel on Climate Change. At the same time, the study indicates 21st century sea-level rise could be kept to less than two feet if greenhouse gas emissions are aggressively and immediately reduced.

Climate Central has co-released maps and decade-by-decade local sea-level rise and coastal flood risk projections that integrate this new research, to help users explore its implications.

Climate Central developed global maps corresponding to the different projections, and calculated that for the median projection in 2100 under the unchecked pollution scenario, water could permanently inundate land now home to 153 million people (unless new protections are built).
Nation-by-nation results under multiple scenarios are available for download here or as dataset 6 of the Supporting Information published with the paper.
