Maureen Raymo, a marine geologist at Lamont-Doherty Earth Observatory whose name is connected with key theories about how ice ages wax and wane and how sea levels change, has been elected to the National Academy of Sciences, one of the highest honors awarded to scientists in the United States.

“If climate change is having an impact and is making droughts worse, then we should see this in the record over several centuries—and we do,” said the study’s author, Benjamin Cook.
The team aboard the JOIDES Resolution just finished at their first coring site off southern Africa. The first results? “Awesome.” Sidney Hemming describes the process in words and photos.
Sidney Hemming and her team have started examining their first sediment core from off southern Africa. It appears to contain about 6 million years of history.
As they get to know their ship, the scientists aboard the JOIDES Resolution prepare to drill their first sediment cores along the Natal Valley off the coast of southern Africa.
Sidney Hemming and the scientists aboard the JOIDES Resolution conduct the final preparations for their research cruise off southern Africa and introduce a girls’ school group from Mauritius to science at sea.
A new study uses sediment cores to track the expansion and retreat of glaciers through time, and finds that they are retreating quickly and are more sensitive to temperature change than previously realized.
The Earth Institute will offer nine research assistant opportunities for undergraduate students during the Spring 2016 semester.
With new data, scientists can track back what glaciers did in the past, and how it is related to climate change. This provides a link to predict what could be happening in the next 100, 200, 500 years.
Researchers from eight universities, including Columbia University, are using tree ring and glacier analysis to reconstruct the climate history of the Missouri River Basin in order to give policymakers and water managers better decision-making tools to manage the river.
