Greenland’s Ancient Warm Period Reveals Future Climate Risks

Oct 21, 2025 | physical sciences

About this episode

Studying Earth’s past environments is critical for predicting the impacts of human-driven climate change. By looking at how the Arctic responded to warm periods millions of years ago, scientists can make more accurate predictions about what lies ahead. A groundbreaking study led by Drs. Gina Moseley, Gabriella Koltai and Jonathan Baker at the University of Innsbruck, Austria, has revealed Greenland’s dramatically different past. Read More

German version

Die Untersuchung vergangener Umweltbedingungen ist wichtig. Sie hilft uns zu verstehen, wie der menschengemachte Klimawandel wirkt. Wenn Wissenschaftler die Arktis und ihre Reaktionen auf frühere warme Zeiten studieren, können sie genauere Vorhersagen für die Zukunft machen. Eine bahnbrechende Studie von Dr. Gina Moseley, Dr. Gabriella Koltai und Dr. Jonathan Baker an der Universität Innsbruck zeigt die drastisch andere Vergangenheit Grönlands. Wissenschaftler fanden Mineralablagerungen tief in alten Höhlen. Diese zeigen, dass es im späten Miozän, vor etwa 11,6 bis 5,3 Millionen Jahren, deutlich wärmer war. Read More
