Document Summary
Week 5 lect 1: glacial/deglacial time scale, shorter time scales short amplitude in temperature but much faster, new data (marine sediments, ice cores) better data, can cover a larger part of the global. Glacial scale climate lgm: can express regional and continental changes rather than global changes, last glacial maximum (21,000yrs ago) Co2 level effect methane in the atmosphere. Seasonal insolation effect amount of radiation. Very comparable to our current conditions can be removed no really a forcing of the temperature: the amount of ice is much more than today, co2 levels were lower. Glacial scale climate reconstruction lgm: 2nd map = net changes or anomalies from the regions. Appearance of very different development of ice, very high development of ice in the antarctica. Laurentide & cordilleran about 40% of all ice at the time (north. Slight warmer condition for pacific or tropic level. Glacial scale climate reconstruction lgm: 2.
