In this very special episode, I am joined live in Berlin by the "Godfather of Climate Science," Dr. James Hansen.
Dr. James Hansen is the former director of the NASA Goddard Institute for Space Studies, and is now the Director of the "Climate Science, Awareness and Solutions Program" at Columbia University's Earth Institute. He was one of the first to bring climate change to the public eye with his famous testimony before the U.S. congress in the 1980s. Since then, he has continued to be at the forefront of the climate debate. 
We discuss a wide range of topics: 

The emergence of the science on global warming from rising CO2 levels
Dr. Hansen's experience as a high-caliber climate advocate
The shift from climate deniers to climate lukewarmists
The two most important climate actions for Dr. Hansen, a carbon tax and support for nuclear power
Why Dr. Hansen didn't go to COP26
The anti-nuclear lobby
The virtually unlimited government support for renewables
Differential responsibility for climate change
The contrast between German and Chinese approaches to climate action
Fukushima, alarmism, and anti-nuclear NRC picks
Reflections on geoengineering
