From the Radiolab podcast: Three tree ring scientists walk into a bar…
At a tree ring conference in the relatively treeless city of Tucson, Arizona, three scientists walk into a bar. The trio gets to talking, trying to explain a mysterious set of core samples from the Florida Keys. At some point, they come up with a harebrained idea: put the tree rings next to a seemingly unrelated dataset. Once they do, they notice something that no one has ever noticed before, a force of nature that helped shape modern human history and that is eerily similar to what’s happening on our planet right now. With help from pirates, astronomers and an 80-year-old bartender, this episode will change the way you look at the sun. (Warning: Do not look at the sun.)
