Ice core analysis reveals cooling period 6 M years ago

Ice core analysis reveals cooling period 6 M years ago. Scientists have extracted ice cores from Antarctica dating back 6 million years, which represents the oldest ice cores directly dated, according to a study in the Proceedings of the National Academy of Sciences. Analysis of water and air from the ice reveals a significant cooling period […]

Community engagement and outreach near Kluane Lake, Yukon, Canada

Introduction: The Gulf of Alaska (GoA) region, which includes Alaska, the Yukon and parts of British Columbia, contains over 40 mm of sea level rise in its many alpine glaciers and icefields (Farinotti et al., 2019). The heavily glaciated region also sustains some of the world’s highest levels of warming and glacier mass loss, even […]

UMaine Climate Change Institute leader steps down as the field faces challenges

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 […]

IceSpec: An ice-core hyperspectral imaging framework. PAGES Magazine. 2025. Kurbatov A.V., Breton D.J., Hargreaves G., LaBombard C., Nunn R., Rumsey R. and Zhizhin M.

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.

Miocene and Pliocene Ice and Air from the Allan Hills Blue Ice Area, East Antarctica. PNAS. S. Shackleton et al. 2025 – A. Kurbatov, C. Introne and others

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 […]
