What would the world look like if all the ice currently on land (more than 5 million cubic miles) melted? Well, we wouldn't be living in Waterworld, but the drastic sea level rise would have very destructive implications for many of the world's major cities.

These amazing images come from National Geographic magazine's interactive "If All The Ice Melted" graphics up on their website. In the image, sea level has risen 216 feet.

They let us post a few of the maps here.

Bye-bye Florida. Oh, and the Gulf Coast. And most of the East Coast. San Diego would be gone and the hills around San Francisco would be turned into islands. Destroyed cities: Houston, New Orleans, Tampa, Miami, Charleston, Norfolk, Boston, and Montreal.

Destroyed cities: Karachi, Baghdad, Dubai, Calcutta, Bangkok, Ho Chi Minh City, Singapore, Hong Kong, Shanghai, Tokyo, and Beijing.

Don't worry too much though, it would take thousands of years for the ice itself to actually even go through the melting process, according to National Geographic.

They have a ton of other great climate change graphics and charts over there, too.
