After a short break, our climate podcast Heatwave returns. It is now hosted by sociologist Vojtěch Pecka, author of the successful publication The Factory of Lies. In the opening episode, he talks to American historian Spencer R. Weart, who was for many years the director of the Center for the History of Physics at the American Institute of Physics. Weart is the author of one of the most important books on the history of climate science and the discovery of anthropogenic global warming - The Discovery of Global Warming. In addition, Weart maintains a database covering the history of climate science, which can be found on the American Institute of Physics website.
