Today we’re sharing an episode of Catalyst, a podcast hosted by Shayle Kann and produced by Canary Media. The topic is a controversial one: solar geoengineering — the idea that we can quickly cool the planet by blocking a small amount of sunlight from reaching Earth. Doing so could have uncertain ripple effects throughout the world’s ecosystems, so very few climate scientists advocate solar geoengineering. Still, learning about these ideas reminds us, for better or worse, how much power we humans have to radically reshape life on Earth. This episode dives into the science and ethics of it all.
