Sea Level Rise Maps now up to +60m
This has been up here before, but (by popular demand) I've now extended it to cover sea level rise scenarios up to +60m. So now you can work out where the best seafront property will be when Antarctica melts...

I had no idea this was a Mefi's Own™ project! Neat.

For an illustrated guide to all of the major changes such a rise would wreak and what it might mean culturally, check out "the world of Dubia."

(Also, a couple of bugs: The flood overlay stops loading north of a horizontal line running through St. Petersburg, Russia and the southern coast of mainland Alaska. And this might be a Google Chrome issue, but the map tiles along the bottom of the screen seem to be disabled at every zoom level, so up to one-fifth of the map surface doesn't display as you scroll around.)

@odinsdream - I think those are holes in the underlying NASA data.

@Rhaomi - The underlying NASA data only covers latitudes 60 degrees from the equator.

Niiice, my house survives the 60m zombie mermaid apocalypse!

As to the World of Dubia - I'm not convinced there's enough water in the world for a 110m sea level rise. I chose +60m as my most extreme scenario precisely because that's roughly what you get if the entire southern polar cap were to melt. I'm not sure where the other thousands of cubic kilometres of water might be hiding.

I also didn't know this was a MeFi project! We just used it in a seminar I'm taking on ecological disasters. This is awesome, thanks!

(Amusingly, under a 60m sea level rise, the only part of my university that remains above water is the Marine Sciences Research Center.)

Wasn't all of middle america a shallow salt water sea in the Mid-Cretaceous?

How much of a sea level rise is that?

did you make this with KML polygons?
