Paleoclimate Archives
Paleoclimate archives consist of geologic (e.g., sediment cores) and biologic (e.g., tree rings) materials that preserve evidence of past changes in climate. They contain substances or features (climate proxies) that can be sampled and analyzed using a variety of physical and chemical methods. Using results from the analyses of proxies in archives, scientists reconstruct changes through time and...
