Study suggests costs of building flood protection from global warming far less than flood repair (Phys.org) —A team of researches with members from several European countries has concluded that it would be far more cost effective for most coastal area economies to employ flood prevention strategies rather than simply pay to clean up after flooding that occurs due to global warming. In their paper published in Proceedings of the National Academy of Sciences, the researchers describe likely flooding scenarios in the future as ocean levels rise due to global warming and the possible costs of building structures to prevent flood damage.
Global warming, it appears, is here to stay, thus, it’s time, the researchers suggest, to start making plans for dealing with the inevitable flooding that will occur as ocean levels rise due to warmer water and melting snow and ice. They note that approximately a billion people currently live in areas that are likely to be at risk—low-lying coastal areas. And since it’s not likely that towns and cities will be moved farther inland, other measures need to be taken. They note that flood prevention strategies are well established, e.g. building levees, barrier islands, etc., thus it’s not difficult to draw up estimates for such schemes for individual areas. What is difficult is convincing municipalities to spend billions of dollars on preventing floods that won’t occur for many years. http://phys.org/news/2014-02-global.html
