Fire And Ice

    Listen

    We’re going to take you from the hottest of the hot, to the coldest of the cold on this episode. We explore how cold can save lives, and we take a trip to the coldest tundra on Earth. Then we heat things up again to figure out the science of sweat, plus what climate change will mean for the summer Olympics. 

    Get ready to feel a chill deep in your bones despite the hot summer heat.
