Comparisons between peaks in megafaunal bone abundance and climate proxy records. The terminology and timing of the GIs are from Rasmussen et al. (47). (Top) Methane concentrations in the GRIP core (47). (Middle) The δ¹⁸O record from Chinese speleothems (73). The dynamics of δ¹⁸ in southeast China are dominated by changing evaporative source areas and transport distances of precipitation. (Bottom) δ¹⁸O in the GRIP core (47). The close correlation between the CH₄ record and the δ¹⁸O record attests to the global extent of the climatic events recorded in Greenland. ppvb, Parts per billion by volume; VPDV, Vienna Pee Dee Belemnite.
