New research project on Arctic climate change impacting indigenous communities in Alaska’s Yukon-Kuskokwim Delta.
A new research project led by Julie Brigham-Grette will seek to connect a changing Arctic climate with problems related to water and sanitation affecting indigenous Yupik and Cup’ik communities in Alaska’s Yukon-Kuskokwim (YK) Delta. The project is supported by a new $2.98M National Science Foundation (NSF) grant. Read more in the UMass news release.
Research study the first to comprehensively account for the hydrological impact of lithium mining
In a new study published in the journal Earth’s Future, David Boutt, postdoctoral associate Brendan Moran and colleagues at the University of Alaska-Anchorage investigated two of the most important factors in determining whether lithium is obtained responsibly: the age and source of the water the lithium is found in. Additional detail of the study is detailed in the UMass news release and journal article.
New Study Links Sixth-century Droughts to the Rise of Islam
Ray Bradley and Stephen Burns are coauthors on a new paper published in the journal Science that links sixth century droughts in the ancient South Arabian kingdom of Himya with the rise of Islam. The research suggests, not surprisingly, that climate history is an important factor in the history of human civilization. Read more in the UMass news release and the journal article.
CSRC researchers investigate Mid-Pleistocene Transition, a dramatic shift in earth’s climate 1.2 million years ago
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.
Boyang Zhao and colleagues publish study linking drought and abandonment of Norse settlements in southern Greenland in the 15th century
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.

Julie Brigham-Grette and Rob DeConto address an international symposium of world’s leading polar researchers
Recently, CSRC’s Julie Brigham-Grette and Rob DeConto were invited to address an international symposium of the world’s leading polar researchers in Monaco. Their full remarks can be seen on YouTube at the 3:25 and 3:48 marks. Read more in the UMass news release.
Anna Ruth Halberstadt leads study resolves a long-standing discrepancy in the geologic record
In a paper publish recently in the journal Geology, Ruthie Halberstadt and coauthors Rob DeConto and Douglas E. Kowalewski addressed a discrepancy between marine data from the Ross Sea and data collected in the McMurdo Dry Valleys. Ruthie completed this research as part of her P.h.D. in geosciences. Read more in the UMass news release and journal paper.
Ray Bradley publishes review article on past extreme tropical hydrological events
In a recent paper published in Reviews of Geophysics, UMass Distinguished Professor Raymond Bradley synthesized information from lake sediments, stalagmites, and offshore marine sediments to provide a comprehensive record of changes over the past ∼70,000 years. He and coauthor Henry Diaz describe how freshening of the subpolar North Atlantic led to a rapid reduction in the northward flux of heat by the ocean, subsequent reorganization of the atmospheric circulation, and, in turn, climate modifications in various parts of the world.
