Dr. Deb took the opportunity to share some technical questions about the causes of global warming in this live show. She commented on the survey of climate scientists and meteorologists, and shared some audio from the 2011 Heartland International Conference on Climate Change from Dr. Nicola Scafetta (Duke University) and Dr. Willie Soon (Harvard-Smithsonian Center for Astrophysics). The link is to the full video lectures which include their graphs and slides. It's good to ask questions!
