A huge swathe of eastern England, most of Denmark, the entire eastern seaboard of the United States, Bangladesh and a huge chunk of China would be lost beneath the sea if all the world’s ice melted, according to maps produced by National Geographic magazine.
The interactive online maps show a radically different planet Earth after land ice in Greenland, the Antarctic and elsewhere all melted. If this happened, it would produce a sea level rise of about 216ft.
“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,” the magazine said.
“If we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80F [26.6 C] instead of the current 58F [14.4C].”
The maps show the Black Sea joining up with the Caspian Sea in Europe, while a vast lake is created in the middle of Australia. Africa fares better than the other continents, but Alexandria and Cairo in Egypt would be lost and the temperature rise needed to melt the ice would make much of it uninhabitable.
