This week on the show Alok Jha meets Lewis Dartnell to discuss his new book The Knowledge: How To Rebuild Our World From Scratch.
Lewis argues that a handbook of key scientific principles and practical tips will be all you need as a survivor of an apocalyptic breakdown of society.
Ian Sample, the Guardian's science correspondent, is joined in the studio by Nicola Davis, Observer Tech Monthly's commissioning editor, and Adam Vaughan, Guardian environment site editor, to rake over the latest science and environment news. They discuss the Intergovernmental Panel on Climate Change report, out this week, the discovery of a new dwarf planet in the solar system that hints at the existence of a Super Earth we can't see, and why Caledonian crows are so clever.
Oh, and we bid a fond farewell to Alok, who is off to join ITV News as their science correspondent after a decade at the Guardian – many of them spent presenting this podcast. We're going to miss him.
