Climate Change Clues from Ancient Volcano

Johann Cold I, a chemistry professor at SDSU, conducts research on climate change by analyzing ice cores from Antarctica and Greenland. His work has uncovered evidence of a volcanic eruption in 1809, which may provide insights into historical climate shifts. The research involves complex methodologies and offers valuable educational opportunities for students. Supported by the NSF, Cold I's work enhances SDSU's reputation and contributes to understanding natural climate change factors.
