Short summary
The 8.2 ka BP event, a global climate anomaly that occurred 8200 years ago, could provide climate teleconnection information for the simulation of abrupt climate changes, but there are few quantitative reconstructions of this event. This paper provides a 10-year resolution rainfall record from the East Asian monsoon area during the event, showing the reduced rainfall in southwest China during the 8.2 ka BP period was coupled with Greenland cooling with a possible response rate of 110 ± 30 mm/℃.
