Thanks for at least responding to my actual argument. > It means we literally have no idea what will happen, and there's no way to know if the levies will be high enough or if it will be needed at all. I got some big problems with the climate change mitigation methods which presume anthropogenic nature. The biggest one being, we can reduce our Carbon emissions and stuff, but this solution requires EVERYONE to do it. One defection (like China or India) and it might result in everyone defecting or our solution becoming futile. On the other hand 'building levies' (which is just a way to label the actions which try to fight climate change by negating its effect, require each individual country to act in their own interest and it can be effectively pulled off.
