Sea-level rise exposes coastlines to greater risks of flooding and erosion and is expected to affect millions of additional people each year by late this century. Small islands such as the Maldives, Asian mega-deltas such as in Bangladesh, low-lying coastlines in the United States along the Southeast and Gulf of Mexico, and heavily populated coastal cities in Europe such as London and Venice are among the vulnerable locations. Some small island nations could disappear entirely. Portions of some major coastal cities may have to be abandoned.
