New data published in Science shows that if the planet warms by 2 degrees Celsius, sea levels will rise about 20 feet. It's pretty much a given that this will happen, it's just a matter of when—it could be by the end of the century. A 20-foot rise is no where near Linn's extreme depiction of a 100-foot rise, but it would still radically alter our coastline. The group Climate Central created an interactive map (h/t Gizmodo) that shows what this would mean for major cities in the United States. In New York, it means that entire neighborhoods would be wiped out and 1.8 million people would be displaced.
It's gonna be like this year round!
