Climate Change and the World's Oceans
Jane Lubchenco, Ph.D., Oregon State University

The oceans are changing as Earth warms: ocean water is warmer and more acidic, sea level is rising, and storms are becoming more intense. Life for millions of people who live on the coast is changing, and so is life beneath the surface. Dr. Lubchenco will summarize some of the better understood changes—corals bleaching and ecosystems being disrupted as some species move to new locations—and will also discuss some unexpected events, such as the emergence of a seasonal dead zone along the Pacific Northwest coast. Learn steps that can help address the underlying changes as well as those likely to be unsuccessful.
