A series of climate oscillations around 8.2 ka revealed through multi-proxy speleothem records from North China
Abstract δ 18 ± 1 σ are identified from 8.52 ka in our speleothem record. The earlier two are characterized by enriched 18 O at ∼ 8.50 and 8.20 ka, respectively, suggesting a prolonged arid event, which is supported by the positive trend in δ 13 δ 18 δ 13 δ 13 C suggests the recovering degree of resilient ecosystem responding to different rebounded rainfall intensity. A comparison with other high-resolution records suggests that the two droughts–one pluvial pattern between 8.52 and 8.0 ka is of global significance instead of being a regional phenomenon, and is causally linked to the slowdown and acceleration of the Atlantic Meridional Overturning Circulation that was further dominated by the freshwater injections in the North Atlantic.
