Paleoclimate reconstructions from different locations and proxies in northern China. (a) Tree pollen percentages from Daihai Lake50; (b) Tree pollen percentages from Bayanchagan Lake51; (c) Reconstructed moisture evolution based on paleosol development in the deserts and Sandy Lands of northern China52; (d) A moisture record based on the percentages of trees and shrubs in the semi-arid belt of northern China53; (e) Tree and shrub percentages from Erlongwan Maar Lake54; (f) Quantitative precipitation reconstruction from Lake Luanhaizi55; (g) Pollen-based annual precipitation reconstructed from Gonghai Lake56. The dashed line indicates the onset of the Holocene Climate Optimum around 8000 cal BP.
