New tools for action on ocean health

Dawn Wright

How can people set goals for taking care of a system as large as the world's oceans? How is it even possible to know what is needed to keep oceans healthy and productive? The Ocean Health Index establishes a new world standard for measuring how people benefit from, interact with, and affect marine ecosystems, expressed as one number. Dawn Wright (2011) and her colleagues at the Environmental Systems Research Institute are working with Conservation International, Radical Media, and the University of California at Santa Barbara on methods for representing information from the index through maps on the web that will make detailed information easily available to people in every country of the world.

Drying in Southwest U.S. linked to warming in Greenland

The Southwest U.S. dries out when Greenland warms and gets wet when Greenland cools, according to a new study of stalagmite cores co-authored by Julia Cole (2008) and her graduate student Jennifer Wagner. Predicted warming in Greenland means the Southwest can expect drying in the future, posing a huge problem for its growing population.
