Temperature vs Time
Ice core data showing the Younger Dryas
event where there is a sudden drop in
temperature between ~11,000 and ~10,000 years ago.
Time Period for the Younger
Dryas Event
About 14,500 years ago deglaciation was well underway accompanied by a global sea level rise.
Regional warming continued until about ~11,00 years BP, when there was a dramatic cooling almost leading to reglaciation. This cold episode lasted until ~10,000 years BP.
Temperature vs Time
Ice core data showing the Younger Dryas
event where there is a sudden drop in
temperature between ~11,000 and ~10,000 years ago.
This cold episode is identified as the Younger Dryas cold phase. Recent studies show this inteval began with an ~7oC drop in temperature, in only 20 years.
The event ended as suddenly as it had begun with a dramtic increase in temperature of ~7oC.
