This week, Bryony is back, this time to talk to David Wallace-Wells. David is an American journalist and author who often writes about climate change. His 2017 article "The Uninhabitable Earth" for New York Magazine was the publication's most-read article in history. David then turned the article into a book of the same name, which was chosen as Book of the Year, 2019, by The Sunday Times, The Spectator and New Statesman. He has a BA in History from Brown University.  Links Read David's original 2017 article here: https://nymag.com/intelligencer/2017/07/climate-change-earth-too-hot-for-humans.html Read the 2020 Nature Article on RCP 8.5 here: https://www.nature.com/articles/d41586-020-00177-3 Read Jim Hansen's recent paper on climate sensitivity: https://academic.oup.com/oocc/article/3/1/kgad008/7335889 View Bryony's favourite Sankey diagram showing US energy inputs and outputs: https://flowcharts.llnl.gov/
