Blogger Alex Tingle has made enterprising use of Google Maps by designing an overlay that shows the effects of the sea level rising . You can choose your level (up to 14m) and the map will show if a given bit of land would be underwater, and you can toggle between a map view (with placenames) and a satellite view, and you can zoom in and out. Of course, there are lots of caveats since he’s ignored tides and flood defences, the data may be less that 100% accurate, etc. Still, it’s an entertaining and instructive bit of coding. I’m happy to report that my own house will remain dry (though I’ll be dead long before we get to 14m, anyway).
