“…The Earth's climate system during the Holocene has been marked by a series of globally extensive centennial‐scale climate anomalies such as the 2.8, 4.2, 5.5, 8.2, and 9.3 ka events (e.g., Bond et al, 1997; Mayewski et al, 2004). Some of these events occurred at rapid rates with large amplitudes, which may have caused disastrous consequences, seriously affecting the prehistoric human society development (e.g., Carolin et al, 2019; Sinha et al, 2019; Weiss et al, 1993). In‐depth studies of the timing, duration, and structure of these events in different regions are of great significance for a better understanding of their causative mechanisms (Bond et al, 2001; Wanner et al, 2011), which is an important basis for predicting future climate change under the global warming.…”
