Transatlantic Tandem Talk - On Thin Ice: Global Impact of Climate Change in the Arctic

This Transatlantic Tandem Talk features an expert discussion between Prof. Dr. Janet Rethemeyer, Professor for Organic Geochemistry and Radiocarbon Dating at the Institute for Geology and Mineralogy at the University of Cologne, Germany, and Dr. Jannik Martens, University of Cologne alumnus and Postdoctoral Research Fellow at the Lamont-Doherty Earth Observatory of Columbia University.
Moderated by Prof. Betsy Baker, international lawyer based in Alaska.
Welcoming remarks by Dr. Eva Bosbach, Executive Director, University of Cologne New York Office, and Christian Hänel, President, American Friends of the Alexander von Humboldt Foundation.
The Arctic is warming at rates three times faster than the global average. The melting of ice sheets and glaciers increases concerns about global sea-level rise, while the thawing and degradation of Arctic permafrost soils may release large amounts of greenhouse gases, potentially causing additional warming. Although changes in the Arctic may impact the global climate system, thus affecting societies all over the world, our knowledge of the ongoing transformations in this environment remains limited. A better understanding of the Arctic region is needed for scientists to predict future changes and develop mitigation and adaptation strategies. To this end, researchers study climate archives such as ocean and lake sediments and permafrost to find clues about how past changes in Arctic climate affected the environment.
Following the Transatlantic Tandem Talk is a virtual tour through the core repository of the Lamont-Doherty Earth Observatory of Columbia University in NYC which houses over 20,000 sediment cores from across the globe.
