DANSGAARD-OESCHGER EVENTS, ANOTHER WELL KEPT CLIMATE SCIENCE SECRET

Dansgaard-Oeschger Events: Writing in No Tricks Zone, Kenneth Richard discusses papers on Dansgaard-Oeschger cycles, or D-O cycles, which indicate that: “Unlike the relatively stable climate Earth has experienced over the last 10,000 years, Earth’s climate system underwent a series of abrupt oscillations and reorganizations during the last ice age between 18,000 and 80,000 years ago (Dansgaard 1984, Bond et al. 1997, 1999). …There are twenty-five of these distinct warming-cooling oscillations. These include up to 10°C (in the Greenland region) were reached within as little as 50 years or about 2°C per decade.”

One can assert that D-O events apply only to the Arctic, or to Greenland, specifically. However, alarmists claim that a warming of the Arctic and of Greenland are the result of CO2 caused warming. The alarmists have generally failed to discuss D-O Events and to separate this natural variability from the influence of CO2.
