“Atmospheric rivers” are long, narrow bands of highly concentrated moisture that can carry as much water as Earth’s largest rivers and can have profound impacts when they hit the California coast. Join Scripps researcher Marty Ralph as he describes their crucial role in both water supply and flooding across much of the U.S. West Coast, and how improved forecasting can help us harness these California rainmakers.

The oxygen content of earth’s ocean has changed dramatically through time, beginning with essentially no oxygen and rising to present-day levels, with important consequences for the evolution of life. Oxygen levels in modern oceans are also shifting as a consequence of global warming. Learn how low-oxygen settings in the modern ocean can inform us about the “explosion" of animal life more than half a billion years ago, mass extinctions, and the future our ocean.
