Surging Seas Sea level rise analysis by Climate Central

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:
