Greenland: Secrets in the Ice —
CNN's Frederick Pleitgen traveled to Greenland with a team of climate scientists who are gathering up-to-date data on the island's vast ice sheet to guage how much and how fast it is melting. As one scientist on the mission says: "This is where the rubber meets the road when it comes to studying climate change."
