Populations who are most vulnerable to extreme heat include <br />persons over 65 or under five years old; living alone, without air-conditioning, or residing on the <br />topmost floor of a building,- and with an income at or below the poverty line. People who are exposed to <br />heat because of recreational orjob-related activities are also more vulnerable, including athletes, <br />construction workers, and landscape/agricultural workers (Adapting to Climate Change in Minnesota: <br />2013 Report of the Interagency Climate Adaptation Team, 2013). <br />Page171 <br />
