a Ensemble rainfall reconstruction with 1σ uncertainty from Qingtongyang Maar Lake (this study). The orange line indicates piecewise linear trends based on Bayesian change-point analysis56. b Reconstruction of North Atlantic Oscillation (NAO) index based on lake record from southwestern Greenland92. c Temperature difference between extratropical Northern Hemisphere (30°N–90°N) and Southern Hemisphere (30°S–90°S)90. d Alkenone-based summer temperature reconstruction from Qinghai Lake in northeastern Tibetan Plateau96. e Integrated African summer monsoon index with 1σ uncertainty based on six leaf wax hydrogen isotopic composition (δDwax) records (Methods, Supplementary Table 10). f Normalized dust records based on dolomite (brown) and carbonate (purple) from the Gulf of Oman86 and Ca/Ti ratio (gray) from the Nile Delta85. g Saharan vegetation cover change as reflected by the influx rate of Poaceae pollen from Lake Yoa83.
