Someone did a google maps/NASA global warming data mashup. It's kinda fun to play with. For instance, here's what Sydney airport will look like with a 3 meter rise in sea level:
And here's a worst case scenario, a 10m rise!
Hope your 747 has skid-floats for landing gear!
Much to my sadness, however, even a 15m rise in sea level won't flood out Washington, DC. Curses! Here I thought that would be one GOOD effect of global warming!
(BTW, I used to live here, but now I live two blocks away, over here.)
