Killer Heatwave
Killer Heat is expected in the United States, with serious climate choices and future survival during dangerously hot days ahead.
The hot weather will spread across much of the central and eastern states over the next few days. Chicago, Detroit, New York City and Washington, D.C. may see what will soon be the very highest degree.
About 50 million Americans live where some level of heat alert is in effect. These include the very young, the elderly, those without air conditioning and those participating in strenuous activities, who are susceptible to heat stroke.
