GE354: Glacial and Quaternary Geology
Glacial and Quaternary Geology

Mean global temperatures of the past 5.5 million years, reflected in glacial-interglacial cycles since the onset of North Pacific Ocean stratification in the late Pliocene. [Notice in both diagrams that time runs from right to left.]
Below, the record of later Pleistocene CO2 and dust in the atmosphere, as recorded in the Vostok ice core from Antarctica. Note that CO2 has naturally ranged from about 180-290 ppm over this time interval in the atmosphere. It has climbed from 310 to 400 ppm since 1961; only the naive or self-deluded can believe that human activities had nothing to do with this increase.
