... • C decade − 1 since the 1950s and have been suggested to be one of the most sensitive areas to global climate change (Kuang and Jiao, 2016;Liu and Chen, 2000). The quantitative temperature reconstructions based on lacustrine sediment records have been synthesized in the SE Tibetan Plateau during the past decades, including records from Lake Lugu (brGDGTs, Zhao et al., 2020), Lake Tiancai (diatom, Wang et al., 2021b;chironomid, Zhang et al., 2019;Zhang et al., 2017), Lake Cuoqia (brGDGTs, Zhang et al., 2022a), Lake Tingming (brGDGTs, Sun et al., 2021), Lake Chenghai (isoGDGTs, Sun et al., 2020), Lake Qinghai of Yunnan (brGDGTs, Tian et al., 2019;Zhao et al., 2020), Lake Ximenglongtan (brGDGTs, Ning et al., 2017), Lake Ximenco (pollen, Herzschuh et al., 2014), Lake Chenco (pollen, Lu et al., 2011), Hongyuan Peatland (brGDGTs, Yan et al., 2021) and Lake Yidun (pollen, Shen et al., 2006). These studies have attempted to quantitatively reconstruct temperature variability since the deglacial and Holocene period and identify their potential driving forces. ...
