Some of the most cited “havens” in research by national organizations and in news media are older cities in the Great Lakes region, upper Midwest and Northeast. They include Ann Arbor, Michigan; Duluth, Minnesota; Minneapolis; Buffalo, New York; Burlington, Vermont; and Madison, Wisconsin. Yet each of these cities will likely have to contend with some of the greatest temperature increases in the country in the coming years. Warmer air also has a higher capacity to hold water vapor, causing more frequent, intense and longer duration storms.
