Short summary
We use multi-proxy speleothem records to reveal a two droughts–one pluvial pattern during 8.5–8.0 ka. The different rebounded rainfall quantity after two droughts causes different behavior of δ13C, suggesting the dominant role of rainfall threshold on the ecosystem. A comparison of different records suggests the prolonged 8.2 ka event is a globally common phenomenon rather than a regional signal. The variability of the AMOC strength is mainly responsible for these climate changes.
