Storm Surges Congress" in Hamburg that "through the effects of climate change and extensive human use of coastal areas, storm surge risks could rise worldwide." According to Prof. Nicholls from University of Southampton, “(r)ecent predictions of the OECD assume that the risk of being hit by a so called one in hundred years flood will be multiplied for large harbor cities worldwide by the year 2070”.
While coasts in Germany should be well protected for the next two decades, according to Hans von Storch, this might change in the future: “Between 2070 and 2100 rises in maximum storm water levels in the range of three to eleven decimeters are conceivable along the entire German North Sea coast”.
Attention: I just DELETED a quote from Hans von Storch in Hamburger Abendblatt, Sept. 15th., which I had posted here originally. Hans let me know that this quote was not authorized (see comments). This is, I guess, how many discussions start: from a fake quote. I fully respect Hans' intervention, of course. It doesn't make any sense to start a discussion on basis of something that was never said. Or start it with a correction. Anyway, I am afraid that's the way many discussions go!
