Indeed, about 20% of the Netherlands are already beneath the sea level. Sea levels rise slowly and the Netherlands are rich. I expect the Dutch to simply build bigger dikes. In fact maybe they will not even have to. The current installations are probably already designed to hold even at a noticeably higher sea level for safety reasons. At least I cannot remember ever hearing about flooding disasters in the Netherlands during my lifetime, despite the fact that the land is coastal, flat, and beneath or close to the sea level. Kind of embarrassing actually. I am sitting in neighboring Germany and we seem to have a major flooding disaster every couple of years.. and just because of the natural water level fluctuations in the rivers! I do not mean to say that rising sea levels are not a serious problem.. just probably not for the Dutch.
