Climate Change Institute

The institute will have an interim director until June 2027. Paul Mayewski (left) stepped down as the director of the Climate Change Institute at the University of Maine this fall. Dan Sandweiss (right) will lead the institute as interim director for the next few years. Amid a tumultuous time for climate change research, Paul Mayewski […]

https://pastglobalchanges.org/publications/pages-magazines/pages-magazine/138632 We developed a novel hyperspectral line-scan imaging system for ice cores. The system nondestructively captures light-scattering features via dark-field illumination. Its calibrated visible and near-infrared spectral data enhance analysis and archiving, advancing research on stratigraphic impurities, ice dynamics and paleoclimate.https://doi.org/10.22498/pages.33.2.50 “IceSpec: An Ice-Core Hyperspectral Imaging Framework.” 2025.

 www.pnas.org/doi/10.1073/pnas.2502681122 with DOI number 10.1073/pnas.2502681122 Paper reports the discovery of ice, that is up to 6 million years old. Isotopic temperatures from this ice indicate progressive cooling over the Pliocene; enigmatic basal ice from the Miocene is characterized by even warmer temperatures and may reflect a relic from the adolescent days of the Antarctic ice […]

Jefferson Cardia SIMÕES has been elected a fellow of the World Academy of Sciences/TWAS [TWAS UNESCO (https://twas.org/)]. The nominee has made significant contributions to the science of ice cores and is one of the most distinguished Latin-American glaciologists. His achievements include reconstructing acid pollution in Svalbard ice cores and detecting arsenic and uranium pollution in […]

Newsweek reported on the melting of The Alsek Glacier in Alaska’s Glacier Bay National Park, which has created a new island in Alsek Lake. The new land formation brings to light pre-existing concerns about global warming and rising sea levels. Karl Kreutz, University of Maine School of Earth and Climate Sciences director and Climate Change […]

Climate Change Institute Everest researchers (Mariusz Potocki and Paul Andrew Mayewski) recently released results  from the highest ice core ever recovered https://doi.org/10.31223/X50X7C Photo by Dirk Collins, National Geographic. Abstract We present a unique atmospheric chemistry record from the highest ice core ever recovered (8020 m, South Col Glacier (SCG), Mt. Everest), that captures ~400 years of deposition […]

Bloomberg cited a data visualization from the University of Maine Climate Change Institute’s Climate Reanalyzer for a story on climate change and hurricane season.

The Portland Press Herald interviewed Paul Mayewski, director of the University of Maine Climate Change Institute, on the future of extreme weather events in Maine. “Climate change will continue. These extremes are going to continue,” Mayewski said. “And changes aren’t necessarily going to be gradual.” The city of Portland is currently updating its emergency preparedness […]

The devastating Black Summer of Australia in 2019-2020. The record-breaking Los Angeles wildfires of 2025. These aren’t isolated incidents, but rather stark indicators of a growing global crisis where climate change and wildfires form a devastating feedback […]
