The goal of this course is to present an overview of the methods used to reconstruct the Earth's climate history and the techniques used to determine the timing of environmental changes. Paleoclimate data from proxy records, such as ice cores or tree rings, provides a longer perspective on climatic variability than is possible from instrumental or historical records. The graph above shows the rapid increase in the average Northern Hemisphere temperature during the last century with respect to the last 1000 years, and the dramatic warming in the most recent decades. Is this change related to natural variability or caused by human activities? Particular emphasis will be given to the climatic changes during the late Cenozoic. Topics to be discussed will include: paleoclimatic reconstruction, climate and climatic variation, dating methods, ice cores, marine and sediments, corals, spelothems, soils, pollen, dendrochronology, documentary data, and paleoclimate models.
