East Asian summer monsoon(EASM)precipitation affects the lives of billions of people and impacts the stability of fragile desert ecosystems in central Asia[1].Therefore,many studies have focused on understanding the variability of the EASM and its relationship with insolation,ice sheet,and C0_(2)forcings[1-3].Evidence for EASM variability is preserved in the eolian dust sequences on the Chinese Loess Plateau(CLP),which highlight the importance of Northern Hemisphere(NH)ice sheets,C0_(2)levels,and insolation in controlling the strength of the EASM during the Quaternary[2].In contrast,Pliocene(5.3-2.6 Ma)proxy records of the EASM from the CLP reveal weak orbital signals,suggesting weak sensitivity to ice sheets,C0_(2)levels,and insolation forcing during this sustained warm period[4].These Pliocene proxy records also contrast model simulations which suggest high sensitivity of the EASM to orbital forcing(particularly precession)during this time[5].
