If you visit a place like IJmuiden you'll see that over the last couple of years the various waterworks have been heightened by several meters to account for higher seas. This is a direct response to climate change, the fact that a good part of the country is below sea level definitely adds to the sense of urgency felt to do something about this but we still have 1953 well present in our collective memory to warn us against being complacent.

I always explain NL to visitors as a machine rather than a country. The moment you stop the machine or stop maintaining it the sea will begin to reclaim it.
