A crash course in changing the world.
I am originally from Cuxhaven, where floods occur from time to time. On 09 November 2007 was the last storm surge with water levels about 2,30 - 3,30 m over the mean high tide. Outer harbour and the "Deichstraße" have been flooded, whereas the damage was minimal.
I think in the future when climate change continuing, natural catastrophic events such as weather extremes, storm tides and floods will occur ever more frequently. Informations about storm tides and floods could be share faster by using Ushahidi, because everyone will have a mobile device, so everyone can be warned.
