Betsy dials in from Al Gore’s Climate Training Conference in Tennessee where she is one of 200 Climate Messengers learning the Gore slide show from An Inconvenient Truth and preparing to take it back to their townships and communities around the nation. Here Betsy chats with Resident Scientist Dr. Michael McCracken, who first testified to Congress on climate change in 1975.
