The Younger Dryas climate episode: Older Dryas (14,500-14,700 years ago, brief cold snap), followed by the Bölling-Alleröd warming, then Younger Dryas (12,900 to 11,700 years ago). It ended 11,700 years ago, marking the start of our current Holocene epoch.
Key facts:
- Older Dryas: 14,500-14,700 years ago, a brief cold period lasting decades to centuries
- Bölling-Alleröd interstadial: warming period following Older Dryas
- Younger Dryas: 12,900 to 11,700 years ago
- The Younger Dryas ended 11,700 years ago, marking the beginning of the Holocene
- The term Younger Dryas was introduced by Hart(s) in 1912 at the German Geological Society
