The Southern Ocean, which surrounds Antarctica, is a key region in determining global climate. This video lecture presents data revealing that the Southern Ocean is undergoing an alarming warming trend that may affect climates in the Pacific, Atlantic, and Indian Oceans. What does the Antarctic region tell us about our future? Is Antarctica especially sensitive, so that now it serves as an early warning system for catastrophic change? The speaker questions the belief that human input is local not global. The video is 9 minutes in length.
