Comparisons of organic carbon storage in extant closed-basin lakes with other terrestrial carbon storage and climate background since the LGM. a Organic carbon storage in closed-basin lakes of the Qilian Mountains and b in extant closed-basin lakes. c Northern peatland carbon stock [50]. d Global terrestrial carbon storage [22]. e Global land temperature change and f precipitation change [50]. g Temporal variation patterns of organic carbon accumulation rate at 1000-year bins in closed-basin lakes of the Qilian Mountains and h in extant closed-basin lakes. The gray shadow denotes the period including significant human impacts. The gray dashed line indicates processed CAR values when human impacts have been excluded
