Every second, lightning strikes 50 to 100 times somewhere. It can wreak havoc by starting wildfires and sometimes killing people. But lightning also produces a form of nitrogen that’s essential to vegetation. In this episode, we talk about the nature of these dramatic sparks. Ben Franklin established their electric origin, so what do we still not know? Also, why the frequency of lightning strikes is increasing in some parts of the world. And, what to do if you find someone hit by lightning.Guests:Thomas Yeadaker – Resident of Oakland, CaliforniaChris Davis – Medical doctor and Assistant Professor of Emergency Medicine at Wake Forest University and Medical Director for the National Center for Outdoor Adventure EducationJonathan Martin – Professor of Atmospheric and Oceanic Sciences, University of Wisconsin, MadisonSteve Ackerman – Professor of Atmospheric and Oceanic Sciences, University of Wisconsin, MadisonPeter Bieniek – Professor of Atmospheric and Space Science, University of Alaska, FairbanksFeaturing music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.  Learn more about your ad choices.
