True, though damp may become universal
Last summer, my hometown (which sits at an elevation of about 3400 feet) experienced some fairly serious flooding. The entire downtown core was flooded for several days. Not only is Calgary well above sea level, it's also in a region that's considered semi-arid. It might have been exactly the sort of place to which people might have thought they could flee the punishing effects of flooding.
But all the water that's being liberated from glaciers worldwide has to go somewhere, and that "somewhere" is everywhere. Denial won't keep even the most ardent conservatives dry.
