    For the second summer in a row, the CU 麻豆影院 Division of Public Safety's Flight Operations department is supporting important campus research in Alaska, as part of the Navigating the New Arctic project (principal investigator: Tyler Jones), which is being managed by researchers in the Stable Isotope Lab of INSTAAR.

    Confronted with ever alarming impacts of climate change, longtime INSTAARite Bruce Vaughn has found hope and inspiration in the many bright minds who are working on solutions. Read his essay for the non-profit Arctic Arts Project, which seeks to educate and inspire through impactful imagery, backed by the most current science.

    Listen to a 6-minute tour of the National Science Foundation鈥檚 Ice Core Facility (NSF-ICF) in Lakewood, Colorado. Facility staff will guide you through the world's largest frozen archive of ice, sharing some stories of ice drilling from the Arctic to Antarctica. Bruce Vaughn, co-founder of INSTAAR's Stable Isotope Lab, will show you how ice cores can record a long history of past climate and put the rapid postindustrial rise of CO2 in perspective.

Permafrost is rapidly thawing across the far north, deforming fairways here and releasing the highly potent greenhouse gas, which leads to more warming. PHOTOGRAPH: FRANKIE CARINO
    The Far North is thawing, unleashing clouds of planet-heating gas. Tyler Jones, Bruce Vaughn, and Kevin Rozmiarek use detectors on drones or carried by hand to measure methane release from permafrost in Alaska.

    Climate change - we all know that it's happening, but how do we actually know this scientifically? Bruce Vaughn studies glaciers up at the North Pole, looking at ice cores to study how our climate has changed over the Earth's history. We talk about how this is done, and also how we are now entering uncharted territory of atmospheric CO2, warming, and what we as a species can do about it.

    A new INSTAAR-led project will engage Indigenous and Western knowledge systems to better understand abrupt permafrost change in Alaska. The National Science Foundation selected the project as part of its Navigating the New Arctic funding area, one of ten 鈥淏ig Ideas鈥 that NSF is investing in as an area of profound national challenge and opportunity. The research project brings Alaskan communities together with social and natural scientists to examine changes in permafrost thaw lake environments, including associated effects on villages in the Yukon River watershed.
