On The Science Revolution this week is Dr. Michael Mann on the new Climate War. He shares how fossil fuel companies have waged a thirty-year campaign to deflect blame and responsibility and delay action on climate change. And Dr. Eric Feigl-Ding drops by warning us the coronavirus could be a ‘thermonuclear pandemic.’ He'll also talk about the new Covid variants and what he would do differently. Plus Severine Fleming, from Greenhorns, is here about food security, regenerative agriculture and the hidden value of local food.
