Cities have long made plans for extreme heat. Are they enough in a warming world?

CHICAGO (AP) — With Earth breaking average heat records, cities are sure to be giving a fresh look at their readiness plans for temperatures that can kill. Dire heat waves in the past have prompted effective efforts by cities to do better at protecting people — especially their most vulnerable. A heat wave in Chicago in 1995 killed more than 700 people. The city responded by developing an emergency plan that includes a massive push to alert people to the coming danger — and connect people with the resources they may need to survive it. Many other cities have adopted similar measures. But experts say the inequality that makes some people more vulnerable to the heat is a problem that persists.
