Alison reflects on building a career in remote, high-latitude field science as a queer woman in a discipline that has not always been welcoming, and why visibility and inclusion matter for the future of climate science.In This EpisodeWhat ice cores are and how scientists extract themHow ice preserves a detailed record of Earth’s atmosphereWhy the Arctic and high latitudes are warming faster than the rest of the planet Key TakeawaysIce cores are not projections; they are direct physical recordsClimate change is already visible in the planet’s deepest archivesWho does science—and who is supported to lead—shapes what we learnAbout the GuestAlison Criscitiello is the Director of the Canadian Ice Core Lab at the University of Alberta. Her work focuses on ice core science, climate reconstruction, and the preservation of irreplaceable polar climate records.
