Princeton University professor Michael Oppenheimer says without significant changes, the earth's ice sheets will melt. If and when that happens, the sea level would rise up to 40 feet. That would mean catastrophe for many regions of the world, including the U.S. After studying climate change for some three decades, Oppenheimer says public and political opinion are finally shifting. The global warming scholar is coming to town to speak at the San Diego Natural History Museum, and will visit with Full Focus.
