In case anybody thinks the sea level rise is all due to global warming, the fine print on the map says that it shows where "local sea level rise projections were combined with storm surge and tidal statistics to estimate the decade by when there is an at least 1 in 6 chance of different water levels occurring, at least once." (see
http://sealevel.climatecentral.org/maps/about-surging-seas-map/ ). This is a pretty low bar, and storm surge will be much more of a factor than increases from global warming. Of course, nobody really knows how much global warming will cause the sea level to rise in the future, nor the strength of future storms. It's all a computer model somewhere.
Ms. Eveleth does the Smartplanet community a disservice by not pointing out these facts behind the study in her article.
