The marine environment is changing rapidly due to carbon dioxide emissions into the atmosphere, which are warming, raising, and acidifying the ocean. While we need to redouble our efforts to reduce such emissions, it is now unlikely that this action alone will be enough to avoid serious marine impacts. Dr. Greg Rau will discuss the unprecedented nature and magnitude of the stresses the ocean now faces, some new approaches to avoiding or lessening the impacts, and the need for policies that support the emergence, evaluation, and development of new marine and planetary management strategies. Rau is a senior research scientist at the Institute of Marine Sciences at the University of California, Santa Cruz.
