We speak with world-renowned climate scientist Michael Mann, who was just awarded more than $1 million in a defamation lawsuit against two right-wing critics who smeared his work connecting fossil fuels to rising global temperatures. He joins us to discuss the importance of resisting climate denialism through free scientific inquiry and expression. “We all pay the price when scientists don’t feel empowered to speak out about the implications of their science,” says Mann. Mann says he hopes his legal win will protect others who have been silenced by the threat of defamation so that “scientists will feel more comfortable in leaving the laboratory and speaking to the public and policymakers.”
