The rise of the Vikings was not a sudden event, but part of a long continuum of human development in the harsh conditions of northern Scandinavia. How did the Vikings make a living over the long term, and what might have influenced their brief florescence? Today, their experiences may provide a kind of object lesson on how changing climate can affect civilizations.
In recent years, scientists have discovered hundreds of lakes lying hidden deep beneath the Antarctic ice sheet. Now a team of researchers has found the remains of at least one sub-ice lake that existed when the ice was far more extensive, in sediments on the Antarctic continental shelf.
As the world warms due to human-induced climate change, many scientists have been projecting that global rainfall patterns will shift. In the latest such study, two leading researchers map out how seasonal shifts may affect water resources across the planet.
Billy D’Andrea, a Lamont-Doherty Earth Observatory paleoclimatologist and Center for Climate and Life Fellow, is investigating the relationship between environmental change and characteristics of early settlements in Norway’s Lofoten Islands.
Yael Kiro, an associate research scientist at Lamont-Doherty Earth Observatory, has received the 2017 Professor Rafi Freund Award from the Israel Geological Society for work published on the ancient climate history of the Dead Sea.
Rainfall patterns in the Sahara during the six-thousand-year “Green Sahara” period have been revealed by analyzing marine sediments, according to new research.
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.
