A Mere 200 Feet

“These reports overturn long-held assumptions about the stability of Greenland’s glaciers: until recently, scientists had predicted that Greenland’s ice sheet would stabilize once the glaciers close to the warming ocean had melted. The discovery of ice-bound fjords reaching almost sixty-five miles inland has major implications since the glacier melt will be much more substantial than anticipated. The Antarctic and Greenland ice sheets combined contain over 99 percent of the Earth’s glacial ice. If they were to melt completely, they would raise global sea levels a virtually inconceivable 65 meters (200 feet).”

—Ashley Dawson, “We Should Be Talking About the Effect of Climate Change on Cities.” Longreads.com. October 2017.

The U.S Geological Survey has a sea level rise viewer that can estimate the impact of an extra six feet at sea level will have on the coasts in the United States. At two hundred, it’ll obviously be much worse.
