With Irma and power failure, Miami feels deadly heat

MIAMI, Florida - Miami is a city that lives on air conditioning. When it fails, people can die.

After Hurricane Irma knocked down power lines and disconnected the cooling system at a nursing home north of Miami this month, 11 residents perished when temperatures inside soared.

Florida Governor Rick Scott blamed management at the facility for allowing patients to endure sweltering conditions as the heat index - a measure of combined heat and humidity - passed 38 C.
