GEOG 205 Lecture Notes - Holocene Climatic Optimum, Tibetan Plateau, Taphonomy
Document Summary
March 18th, 2013: slow climate change: the climatic optimum of hypsithermal this topic is gradual climate change, as opposed to drastic climate change like the. We will be focusing on prairie expansion & lakes in the sahara. Prairie expansion in na: some of the best evidence for this comes from na kirchner marsh, N hemisphere in the summer, earth is most distant from the sun (aphelion) N hemisphere in the winter, earth is closer to the sun (perihelion) it is the reverse for the southern hemisphere there is greater seasonality in the n hemisphere. During the hypsithermal there was a greater tilt causing even more pronounced differences between summer & winter. During the hypsithermal, the opposite happened: why is there more rainfall in coastal regions, or more intense monsoons with a warmer climate? land heats up faster than the ocean. Pulling in the moist air from the ocean.
