Keeping Cool Without Warming the Planet

Heat kills more people in the United States than any other weather event, and scientists expect the earth to continue to get hotter. Unfortunately, one of the most effective tools we have to combat heat — air-conditioning — also contributes to global warming. The hotter we get, the more AC we’ll need: It’s a conundrum. So how do we keep cool without making the planet hotter at the same time? Host Arielle Duhaime-Ross speaks to Dr. David Hondula, the Director of Heat Response and Mitigation for the city of Phoenix, Arizona; Rachel Kyte, a former U.N. Special Representative, and professor in climate policy and sustainability; and Dr. Daniel Betts, an engineer and founder of the air-conditioning company Blue Frontier.
