"More than 20,000 high-temperature records have been broken so far this year in the United States. And the heat is especially bad in cities, which are heating up about twice as fast as the rest of the planet."
"High temperatures increase the risk of everything from asthma to allergies, and can even be deadly. But a researcher in Atlanta also sees this urban heat wave as an opportunity to do something about our warming planet.
The story starts at Ebenezer Baptist Church, arguably the most famous place in Atlanta; it was Martin Luther King Jr.'s church and the heart of the civil rights movement.
It's now playing an unexpected role in a new movement: the struggle against rapidly rising urban temperatures. Cities are literally global hot spots."
Richard Harris reports for NPR's Morning Edition September 4, 2012.
