Dr. Michael Mann joins The Science Revolution for the full episode this week. He is the distinguished Professor of Meteorology & Director of the Earth System Science Center at Penn State University- his latest book is "The New Climate War". There's a new study out - have humans passed the 'point of no return' in the Climate Crisis and is there hope? We also talk about storms getting worse with climate change. Plus - what will it mean to return to the Paris Agreement and how will things change with the scientists back in charge?
