New data from the European Copernicus Climate Change Service reveals what scientists have suspected: July 2019 was the hottest month ever recorded on earth. They measured close to 1.2 degrees above pre-industrial levels, brushing up against one of The Paris Agreement goals of preventing warming above 1.5 degrees Celsius. Here & Now's Robin Young talks with Michael Mann (@MichaelEMann), a professor of atmospheric science at Penn State University, about the significance of the findings.
