Sea Change in South Africa

Sea Change in South Africa

Mo Raymo

On a warmer planet, three million years ago, sea levels were higher, and waves lapped what are now these sandy cliffs in South Africa. Lamont-Doherty Earth Observatory paleoclimatologist and marine geologist Maureen Raymo, shown here, is studying ancient shorelines to understand how high the seas rose then, and how high they might climb in the future. This research is part of theĀ Pliomax project, led by Raymo, which is the first systematic effort to search around the world for Pliocene-age beaches and come up with a more accurate estimate of pastĀ sea level.
