Molecules in the Mud: How the Chemistry of Ancient Lake Sediments Can Help Us Fight Climate Change

This talk presented by Dr. Jonathan Raberg explores how molecular fossils preserved in lake sediments can be used to reconstruct arctic and alpine climate patterns spanning hundreds of thousands of years. Discover the importance of branched GDGTs (brGDGTs), a class of lipid-based proxies that provide valuable data on temperature and hydroclimate throughout Earth's history. Learn how analyzing the chemistry of ancient lake sediments contributes to our understanding of climate change and potentially informs strategies to address this global challenge. The presentation, hosted by Geologists of Jackson Hole, offers insights into how paleoclimate research can help inform our approach to fighting current climate change.
