Iceland: The great thaw

Iceland's glaciers are melting at an unprecedented rate, with scientists predicting that they could all be gone 200 years from now. How is this affecting the lives of local people, and the identity of a nation that has ice in its name? Maria Margaronis talks to Icelandic farmers and fishermen, scientists and environmental activists about their (sometimes surprising) responses to climate change, and asks why it’s so difficult even for those who see its effects from their windows every day to take in what it means.
