How would sea level rise affect coastlines?
In many parts of the world, the coastal land is very flat, so even modest sea level rise can lead to substantial changes in coastlines. The images below, courtesy of Jeremy Weiss and Jonathan Overpeck, show how sea level rise would affect coastlines in susceptible areas (see their website). In some areas, a sea level rise of only 3 feet (1 meter) would cause inward retreat of coastlines by tens of miles or more.
