If all the ice on land has melted and drained into the sea, the sea level would rise 216 feet (66 meters) and create new shorelines for our continents and inland seas.

National Geographic created interactive maps that show how would world coastlines look like if all the polar ice caps melt.

Melted Europe

In Europe, a lot of big and famous cities would go the away under the rising seas; like Copenhagen, Amsterdam, Venice, Riga, Lisbon, even London.

On the other side of the Atlantic Ocean, the situation wouldn’t be any better, if even worse, as the whole Florida would be not more, and most of the Eastern Coast of the United States would also go under see, including Boston, New York, Washington, D.C, and New Orleans.

There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all. If we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58.

I would love to see true interactive, GIS-powered, ice melting map. But nevertheless, these National Geographic maps are still a fascinating view of what might and probably will be in the not so far away future.
