It's a problem because so many Americans are unhealthy and more easily succumb to environmental conditions. It doesn't help that these same people flock to areas where they're more vulnerable. There's lots of bad reporting on the increase in heat related deaths since the 1950s which glosses over the fact that few people were fat back then and air conditioning was exceedingly rare. A fraction of the people were living in the hottest areas of the US and those that were could handle it.
