We have a guest on the show today - Ben Franta. Ben is a scientist, science historian, science writer, and activist. He studied for a PhD at Harvard working on solar cells; while he was at Harvard, he became involved in the movement to persuade that University to divest from fossil fuels. After finishing his first PhD, he moved to Stanford to take up a PhD in the History of Science, where he now studies the history of climate politics, and the influence of fossil fuel companies on that politics. His recent article in the Guardian, published on New Year's Day, explained how Edward Teller knew about global warming in 1959 and warned the fossil fuel industry - thirty years before it hit the mainstream.

The first half, which you're about to hear, is a general discussion of the politics of climate change: why has this problem proved so difficult to deal with?

The article that Ben referred to, which details the case for climate activism, was written by Geoffrey Supran and Ploy Achakulwisut; it's on Mashable, and it's called "How You Can Fight Climate Change."

*** Erratum:

Ben mentioned that the UK currently gets some of its electricity imported from Iceland: this is actually a proposed scheme that's not currently operating, but hopefully will in the near future. There is indeed a cable between the UK and France that helps both countries match supply and demand, and the same is true between Denmark and Norway, which both draw the majority of their power from wind and hydroelectricity respectively. It's the way forward! https://www.landsvirkjun.com/researchdevelopment/research/submarinecabletoeurope
