Coastal communities struggling to adapt to climate change are beginning to do what was once unthinkable: retreat. In the face of rising seas, environmentalists in New Jersey acknowledge they can no longer fixate solely on the problem of carbon emissions. Hurricane Sandy made the topic of adaptation unavoidable. Climate scientists who study the acceleration of sea-level rise feel a similar urgency, and many have emerged from their silos to produce better projections. Robert Kopp, director of the Institute of Earth, Ocean, and Atmospheric Sciences at Rutgers University and a co-director of the Lab, explains how this interdisciplinary approach has led to localized forecasting that allows communities to plan.
