ENVI 360 - Paleoclimate

Earth’s climate has evolved with the planet itself as changing boundary conditions in the ocean, atmosphere, cryosphere and lithosphere have caused ice ages, periods of extreme warmth and mass extinctions. Information about these events is contained in the geologic record in the form of fossils and rock sequences, but also in lake and ocean sediments, ice sheets, cave deposits and tree rings. This course will provide an overview of variations in climate throughout Earth history while simultaneously examining the proxies and archives used to reconstruct those changes. We will also construct our own record of paleoclimate using cores from a local lake and a variety of laboratory techniques. Every other spring. (4 Credits)
