For the last year, NPR and National Geographic have collaborated on Climate Connections, a series about global warming. Reporters traveled around the world, to Antarctica, New Orleans, Amsterdam, and beyond.
Today is Earth Day, and two of NPR's science correspondents, Richard Harris and Christopher Joyce, will join us, to reflect on the year-long series. What have you learned about climate change? What questions do you have about global warming? Did a particular piece stand out to you? Did it change your mind?
