Summary: We will critically evaluate the robustness and limitations of the more commonly applied paleoclimate proxies from sediments, carbonates and ice.

Course Description: Climate proxies are sources of climate information from natural archives such as sediment cores, ice cores, corals, and tree rings. Because the instrumental record of climate is short, spanning the last few decades in most places, the geologic record is the only source of climate data for evaluating natural variability on centennial and longer time scales. An enormous variety of paleoclimate indicators are in use. Some provide quantitative information on a specific climate variable, such as sea surface temperature. Many others provide qualitative information on one or more variables. The goal of this course is to critically evaluate the robustness and limitations of the more commonly applied climate proxies from sediments, carbonates and ice.
