In a paper presented at the national meeting of the Geological Society of America in Portland, Oregon, Professor Don J. Easterbrook, Professor of Geology at Western Washington University, presented new data showing that at least 9 significant, abrupt periods of climate warming occurred between 11,700 and 10,250 years ago. These warmings triggered retreat of the Cordilleran Ice Sheet.
Such fluctuating periods of warming and cooling persist to this day (with no help from humans), and there is every reason to expect them to continue.
"Isotope data from Greenland ice cores show a consistent pattern of
fluctuating warm and cool periods over the past 500 years (Fig. 2),"
says Easterbook. "The average period of warming/cooling
oscillations over the past 500 years is 27 years, remarkably similar
to the period of alternation between warm and cool Pacific Decadal
