Unless the world changes the way it deals with vulnerability disasters and climate change, “there’s going to be an increasing number of places where dealing with these disasters is going to be more and more difficult,” van Aalst said in a telephone interview. And in those cases, sometimes the most sensible option, he said, “may be to leave those places.” Such locations are likely to be in poorer countries, he said, but the middle class may be affected in those regions, which aren’t specifically identified in the report. And even in some developed northern regions of the world, such as Canada, Russia and Greenland, cities might need to move because of weather extremes and sea level rise from man-made warming, van Aalst said. In places like van Aalst’s native Netherlands, citizens will have to learn how to handle new weather problems, in this case heat waves.
