Episode 37: The Rise of the Megafire


In the 1980s, fires burned an average of two million acres per year. Today the average is eight million acres and growing. Scientists believe that we could see years with twenty million acres burned, an area larger than country of Ireland. Today I rebroadcast my interview with Michael Kodas who talks about the phenomenon of megafires, forest fires that burn over 100,000 acres, and why the number of these fires is increasing every year.

Kodas is the deputy director of the Center for Environmental Journalism at the University of Colorado-Boulder. He is also an award winning photojournalist and reporter. His book Megafire: The Race to Extinguish a Deadly Epidemic of Flame recently won the Colorado Book Award.

Episode 36: The Ebola Outbreak of 2013


Why did Ebola, a virus so deadly that it killed or immobilized its victims within days, have time to become a full-blown epidemic? That’s what happened in 2013 in when the virus, already well-known to virologists and epidemiologists, broke out in West Africa, infecting twenty-eight thousand people and killing eleven thousand. 

Stephan Bullard, associate professor of biology at the University of Hartford, discusses the 2013 outbreak which is the subject of his new book, A Day to Day Chronicle of the 2013-16 Ebola Outbreak, now out with Springer Press. (Rebroadcast).

Episode 34: Psychology in Extreme Environments


Ben Saunders and Tarka L’Herpiniere haul sledges towards the South Pole in 2013

Nathan Smith talks about the psychology of exploration, specifically the psychology of performance in extreme environments. Smith worked closely with polar explorer Ben Saunders as he attempted to ski to the South Pole and back unassisted in 2013: a recreation of Robert Falcon Scott’s tragic 1911 Terra Nova Expedition in which Scott and his party died on their return journey across the Ross Ice Shelf. Smith helped establish the research module on Extreme Medicine at the University of Exeter and worked as a senior research scientist within the United Kingdom Ministry of Defense. He is also a Fellow of the Royal Geographical Society.

Episode 32: Rethinking Humboldt


Alexander von Humboldt by Friedrich Georg Weitsch (1806)

It’s hard for 21st century audiences to understand the fame and admiration that followed Humboldt after his 1799 expedition to South and Central America. In the early 1800s, he was the most famous explorer in the world. While his fame would be eclipsed by other explorers, especially in the Anglo-American world, Humboldt is working his way back into the conversation. Patrick Anthony discusses Humboldt and his complicated legacy.

Anthony is a PhD candidate at Vanderbilt University. His essay “Mining as the Working World of Alexander von Humbolt’s Plant Geography and Vertical Cartography” recently won the Nathan Reingold Prize from the History of Science Society. It is published in the spring issue of the society’s journal, Isis
