Rising global temperatures can trigger the release of large amounts of carbon stored in permafrost, leading to a positive climate feedback that would acerbate the global warming trend. To better understand the complicated response of permafrost to climate change, we propose a detailed study on stalagmites from the Siberian permafrost region. We focus on the last period of climatic warming, the last deglaciation, and pursue a multi-proxy study to characterize the response of permafrost, soil, and karst system during this period. Specifically, we will measure radiocarbon, calcium isotopes, trace elements, and stable carbon isotope ratios in stalagmite carbonate, and anchor our measurements in time with a suite of high-precision U-Th measurements. These geochemical proxies are still relatively novel, and our study will contribute to their better understanding, in addition of providing detailed information on permafrost stability over the last deglaciation.
