When the oceanic phenomenon El Niño strikes every four to seven years, it wreaks havoc on the world’s weather patterns, fishing and agriculture. University of Maine anthropologist Dan Sandweiss wants to know how ancient civilizations coped with these blows to their way of life.  For the past five years, Sandweiss has been collaborating with researchers […]

Water, sometimes plentiful, other times scarce, is a vital resource to humans and the environment, but finding a balance that keeps the needs of both fulfilled is complicated, especially when combined with climate change concerns. A University of Maine research team studying how shifting climate conditions are affecting water supplies in Maine also is looking […]

Rapid warming and consequent ice-shelf collapse have focused attention on the glacial record of the Antarctic Peninsula. Here, we present the first record of terrestrial organic material exposed by recently retreating ice that bears on past glacier extent and climate in this sensitive region. Radiocarbon dates show that ice on Anvers Island was at or […]

A major puzzle of paleoclimatology is why, after a long interval of cooling climate, each late Quaternary ice age ended with a relatively short warming leg called a termination.We here offer a comprehensive hypothesis of how Earth emerged from the last global iceage. A prerequisite was the growth of very large Northern Hemisphere ice sheets, […]

Prof. Paul Mayewski, director of the University of Maine Climate Change Institute, will travel to Norway this weekend to join an exclusive fraternity of esteemed climate scientists to receive the International Glaciological Society’s (IGS) Seligman Crystal. Since the award was first presented in 1963 — to its namesake, the late British glaciologist Gerald Seligman — […]

University of UMaine anthropologist Brian Robinson and colleagues are looking at archaeological evidence of Atlantic salmon to better understand the effects of global warming.   UMaine News Link

A new paper in the March issue of the journal Nature Geoscience describes the first direct evidence of warm subtropical waters circulating deep inside glacial fjords in Greenland. These source waters are carried north by the Gulf Stream to the subpolar gyre in the Irminger Sea off Greenland’s east coast. Until now, it was unclear […]

A team of world-renowned researchers, including University of Maine Climate Change Institute Director Paul Mayewski, has released a report addressing several urgent questions about Antarctica. The continent is said to hold answers to many of the questions scientists have about what climate change means for the Earth. The findings of Mayewski and 100 world-leading scientists […]

Polar glaciologist Gordon Hamilton, an associate research professor at the University of Maine’s Climate Change Institute, studies ice sheets and their role in modulating global sea levels. He studies the Greenland and Antarctic ice sheets both in the field and from space. As recently as this past summer, Hamilton was in Greenland, where he has […]
