July was the hottest month ever recorded.  Heat waves broke records around the world this summer. Phoenix, Arizona, endured 31 days of 110 degrees or hotter. Sanbao, a remote township in northwest China, hit 127 degrees – a record for the country. And parts of Europe reached over 100 degrees. These temperatures can be deadly. They also wreak havoc on the built environment. As global temperatures creep higher from greenhouse gasses, heat waves will be hotter and more frequent.  So, what exactly is a heat wave and how is it connected to climate change? How are scientists researching these extreme weather events? And what can policy makers do to help mitigate the impact on people and cities?  This week host Bill Loveless talks with author and journalist Jeff Goodell about his new book “The Heat Will Kill You First: Life and Death on a Scorched Planet”. Jeff has covered climate change for more than two decades. His book “The Heat Will Kill You First” examines the impact that rising temperatures will have on our planet. Jeff has also written books on rising seas, sinking cities, and the coal industry. He is a 2020 Guggenheim Fellow and a contributing editor at Rolling Stone.
