Extreme Sea Level Rise Mapped in 3D

April 27, 2017

In January 2017, the National Oceanic and Atmospheric Administration published updated sea level scenarios for the United States. They included a new extreme scenario that would mean roughly 8 feet of global average sea level rise by 2100, but 10-12 feet along almost all U.S. shores outside of Alaska. Scientists consider the scenario unlikely, but increasingly plausible, especially with continued high emissions of greenhouse gases. Yesterday, Climate Central released a suite of new maps, visuals and analyses fleshing out the implications:
