Video: What would be under water if the ice caps melted?

What would the Earth look like if sea level were 216 feet higher than today? Check out this video:

 

Here are some maps of that scenario. As you can see, there is still plenty of land.

 

  • Martin Vargic created the map to depict the planet with sea levels around 260ft (79m) higher than they are today
  • Current coastlines are shown using a dotted line and the areas that will be submerged by water are unshaded
  • In Europe, towns including London, Amsterdam and Berlin would completely disappear as the sea level rises
  • In the U.S., large parts of the east coast would be submerged including Miami, New Orleans and Washington
  • The Amazon would bursts its banks engulfing parts of Brazil, and a huge chunk of Australia would be swamped

Melting the 29,300,000 km3 of grounded ice would produce 26,100,000 km3 of water. Note that melting of floating ice has no effect on sea level. Also, about 2,100,000 km3 of the grounded ice in Antarctica is below sea level [19] and would be replaced by water. Thus, the net addition to the world’s oceans would be about 24,000,000 km3 of water spread over the 361,000,000 km2 area of the world’s oceans, giving a depth of 67 meters. The new ocean area would be slightly larger, of course, since some areas now land would be covered with water. The final result would be around 66 meters (current estimates range between 63 and 75 meters).

What would the Earth look like as a result? If sea level were 66 meters higher than today, the result would be as illustrated below (for the map I used below see this page)
