Guests: Michael Mann, Jennifer Francis, Jennifer Dlouhy

The frigid temperatures around the nation made President Trump question global warming on Twitter, but as scientists keep explaining, there’s a difference between weather and climate. As the East Coast digs out of the “bomb cyclone” and much of the nation copes with freezing temperatures, we’ll look at the connection between cold snaps and climate change. And we’ll discuss what last year’s extreme weather events–hurricanes, wildfires, droughts and floods–tell us about what 2018 may bring. Marty’s guests are Penn State’s MICHAEL MANN and Rutgers University’s JENNIFER FRANCIS. Then, Bloomberg energy and environment reporter JENNIFER DLOUHY tells us about the Trump administration’s proposal to open most U.S. coastal waters to offshore oil and gas drilling.
