In the US, heat contributes to around 1,500 deaths annually, and advocates estimate about half are people experiencing homelessness. They are about 200 times more likely than sheltered people to die from heat-associated causes. “As temperatures continue to rise across the US and the world, cities like Seattle, Minneapolis, New York, or Kansas City that don’t have the experience or infrastructure for dealing with heat have to adjust,” said David Hondula, director of heat response and mitigation for the City of Phoenix.
