Stalagmites as Climate Archive

When combined with data from tree-ring records, stalagmites can open up a unique archive to study natural climate fluctuations across hundreds of years, a research team including geoscientists from Heidelberg University and the Karlsruhe Institute of Technology have demonstrated. The researchers analysed the isotopic composition of oxygen in a stalagmite formed from calcareous water in a cave in southern Germany. In conjunction with the data acquired from tree rings, they were able to reconstruct short-term climate fluctuations over centuries and correlate them with historically documented environmental events.
