For the 42nd episode of Podcast at Ground Zero the topic will be Heat Apocalypses or as Scott likes to call it ThirstMageddon. This show will be the companion and of course the complete opposite to our previous show about cold apocalypses. We are going to talk about the end of the world being brought on by heat. We’ll cover the usual movies, books, etc. as well as our thoughts on possible “real life” heat apocalypse.
Returning to join us for the conversion will be special co-host Michael O. Varhola.
So join Scott, Mike and I on our trek thru the Cursed Earth we think you’ll enjoy the company.

Sherwood, S. C., & Huber, M. (2010). An adaptability limit to climate change due to heat stress. Proceedings of the National Academy of Sciences, 107(21), 9552-9555.
Because combustion of all available fossil fuels could produce 2.75 doublings of CO2 by 2300 (5), even a 4.5 °C sensitivity could eventually produce 12 °C of warming.
We conclude that a global-mean warming of roughly 7 °C would create small zones where metabolic heat dissipation would for the first time become impossible, calling into question their suitability for human habitation. A warming of 11–12 °C would expand these zones to encompass most of today’s human population. This likely overestimates what could practically be tolerated: Our limit applies to a person out of the sun, in gale-force winds, doused with water, wearing no clothing, and not working.
