Maps of the world's future coastlines, as sea levels slowly rise

University of Arizona geology researcher Jeremy Weiss has been tracking ways that climate change affects sea levels - in the distant past as well as the future. Given the rate of global warming today, he and his colleagues estimate that by 2100, ocean levels with have risen at least a meter. And it will continue to rise after that. What will this do to people who live in coastal cities? Possibly dunk their cities underwater. And in the case of Florida, possibly dunk half your state beneath the waves. Here are a few future waterline maps Weiss has produced - some show us at the waterline predicted for 2100 (about a meter higher), and some show us in 2200 and beyond as the waters keep rising up to 5 meters.

In most of these maps, the red areas are where water will appear in centuries to come (water is blue in the before and after shots). You can learn more in Weiss' paper published this week in Climatic Change, his monograph A Coastal Nation, and on his university research site.

Maps of the world's future coastlines? So the whole world is just North America plus Southeast Asia? I suppose the rest will just completely disappear underwater.
