If all the ice covering Antarctica, Greenland, (Antarctica would make about 60 meters of sea-level rise, Greenland about 7.4 meters), and in mountain ice caps around the globe were to melt, sea level would rise about 70 meters (230 feet) and cover all seaside cities.
The user 7LeagueBoots made an atlas of maps that vividly illustrate what will happen to cities located on the shores of the oceans when the world’s oceans rise by 70 meters (230 feet).
Eastern and Southern United States with a 70 meters sea-level rise
North American West Coast
North Sea Countries with a 70 meters sea-level rise
The Mediterranean and Black Seas
Black, Caspian, and Aral Seas
Northern Russia with a 70 meters sea-level rise
The Middle East and India
East Asia and the East China Sea
Mainland Southeast Asia
Island Southeast Asia
If the sea level rises 100 meters, the consequences will be even more frightening.
