a Speleothem δ18O records from Cherrapunji Cave (Cherrapunji-2 and Cherrapunji-2017-1, this study) were used to construct a composite record. Over their contemporary growth intervals, we exclusively use the Cherrapunji-2 record (Supplementary Note 1.1). Error bars show 230Th dates with uncertainties (2σ) for each record (color coded). b Annual lamina thickness of speleothem Cherrapunji-2 and estimated annual growth rate of speleothem Cherrapunji-2017-1. The black box in (b) shows the period with an extremely slow growth rate in Cherrapunji-2017-1, and the corresponding δ18O data in (a) is depicted by dots.
