When trees talk

In their careful records of climate change over the centuries — and millennia — trees offer a kind of crystal ball on the past. But they can also help researchers figure out everything from what happened in Norway during the Black Death to how Nazis hid an enormous battleship from the Allies during WWII to how much it rained in Norway during millennia past, when it was much warmer than today.


Our guests on today's show are Helene Svarva and Claudia Hartl. You can see a transcript of the show here.
