A team of researchers including Kurt Lindberg ’20, the paper’s first author and a graduate student at the University at Buffalo, and CSRC researchers Isla Castaneda, Will Daniels, and Julie Brigham-Grette have published a study in Climate of the Past that investigated a shift in climate called the Mid-Pleistocene Transition. For this they used specific biomarkers to estimate temperature and vegetation properties to reconstruct the past climate. Read more in the UMass news release.

Ph.D candidate Boyang Zhao along with Ray Bradley and colleagues have published a study in the journal Science Advances that finds that extended drought, on top of other factors, may have led to the abandonment of Norse settlements in southern Greenland in the early 15th century. The team used hydrogen isotopes in leaf wax remnants in lake sediments and other data to conclude that the climate became progressively drier during the Norse period.
