Peter Kalmus is one of the country's most visible and engaged climate scientists. He is the author of Being the Change: Live Well and Spark a Climate Revolution and works at NASA's Jet Propulsion Laboratory. Dr. Kalmus has advocated civil disobedience as a necessary means of spurring action to stop the climate catastrophe. Dr. Kalmus wrote a scathing article about the UN’s recent COP 28 climate summit, which was dominated by the fossil fuel industry. He joins today to explain why, as a climate scientist, he wants people to understand the basic fact that we have no choice but to eliminate the fossil fuel industry as soon as possible. 

"In fact, the laws of physics guarantee that it will get much too fucking hot if we keep burning fossil fuels. So, pardon my language, but I don't know what it's going to take. I'm really disappointed because I thought that at this level of heating, of obviousness, of disaster, that everyone would wake up and realize that none of our hopes and dreams will come to fruition if we don't have a habitable planet." — Peter Kalmus
