An encore presentation from early 2021 that speaks to our current summer of floods, droughts, blazing temperatures and extreme weather across the northern hemisphere: Hosts Kate and Medaya are joined by New Yorker staff writer and Pulitzer Prize-winning author Elizabeth Kolbert, whose new book is called Under a White Sky: The Nature of the Future, in which Kolbert explores the many ways humans intervene in nature. Kolbert discusses invasive species, the sinking of New Orleans, the triage plan for climate change and how solar geoengineering might bleach our skies. Also, Karla Cornejo Villavicencio, author of The Undocumented Americans, returns to recommend Children of the Land by Marcello Hernandez Castillo.
