Questions after the flood in Germany

What’s scary is not climate change itself, but the fact that under this slogan nothing useful is being done for people’s safety. If all weather processes are increasing in amplitude, then why has the risk for dams and river beds not been calculated? Apparently, only processes in the future are well calculated. But for the current ones there are no data and models. It’s very similar to “during this time, either the donkey will die, or the padishah, or...”. There is a suspicion that disasters like this will occur more and more often. If all measures had been taken on time (such a flood had already happened here 100 years ago), then no one would have noticed this and the slogan about a “climate catastrophe” would not have been confirmed. But if we do nothing, we will have a remarkably terrible picture.
