A green wave is sweeping through Washington, and it’s picking up Republicans who are eager to share their ideas on clean energy and climate change. But even as Republican lawmakers turn to shaping climate policy, the White House is doubling down on climate denial, forming a “climate review panel” to vet and discredit the already peer-reviewed science on climate change. So where will climate science end up? Ira’s joined by marine biologist Ayana Elizabeth Johnson and climate scientist Michael Mann for a round table conversation about climate politics, policy, and science activism. Growing up, John Urschel grew up playing both math puzzles and high school football, and he would follow both of those passions. After playing for the Baltimore Ravens, he is now currently a mathematics Ph.D. candidate at MIT. He joins Ira to discuss seeing the world from a mathematical perspective and how he was able to balance the challenges of math and football. Albert Michelson was a Polish immigrant who grew up in the hard-scrabble atmosphere of the California gold rush. In his physics career, Michelson also measured the speed of light to an unprecedented degree of accuracy, and designed one of the most elegant physics experiments in the 19th century, to detect something that ultimately didn’t even exist: the “luminiferous ether.” Science historian David Kaiser tells the story of how that idea rose and fell in this interview with Ira and Science Friday’s Annie Minoff.
