Tracking How Glaciers Change Over Time

To study the advance and retreat of Greenland’s glaciers, Lamont-Doherty Earth Observatory paleoclimatologist Billy D’Andrea and his colleagues extracted sediment cores from the bottom of glacier-fed Kulusuk Lake. They found that Greenland’s glaciers are retreating quickly — at a rate at least twice as fast as any other time in the past 9,500 years. Understanding how glaciers melt, and how ice melted in the past, is a critical component to understanding past and future sea level rise and improving risk assessment in the future.

D’Andrea was recently named a Center for Climate and Life Fellow; he will use the opportunity to study and improve understanding of the interactions that took place between the people of Easter Island, their environment, and the climate of the eastern Pacific.
