• Description: Weiss (1) raises interesting points on our article (2). He observes that the Delingha tree-ring ?18O record matches KM-A speleothem ?18O record from the Mawmluh Cave in India, that defines the 4.2-ka event’s global-type stratum (3). This event is also manifested as a multicentennial drought in the Iranian Gol-E-Zard speleothem record (4). Weiss further argues that the Delingha record is also consistent with the 4.2-ka anomaly recorded in low-resolution proxy records from northern China despite inherent limitations of these proxies.
