In the study, the approach evaluating the\nradiative forcing of aerosol was used to analyze the climatic\neffect of dust over the last 140,000 years in the southern\nChinese loess plateau. (1) Radiative effect of dust aerosol\nwas to reduce the solar radiation arriving at the surface and\nthus to lead earth cooling. However, the grain size-driven\nclimatic feedback of dust aerosol was negative on shortterm\nscale, i.e., to weaken the amplitude of climate\nfluctuation. (2) Glacial-interglacial fluctuation was marked\nin most optical properties of dust over the last 140,000 years.\nHigh-frequent millennial scale fluctuations corresponding to\nYounger Dryas, Heinrich events and D-O cycles dominated\nmost optical properties of dust aerosol. (3) The climatic\nfeedback of dust aerosol may be a contributor for the\nclimatic transition between glacial and interglacial periods.\n","author":null,"citation":"Qin, X., Y. Mu, B. Ning, and Z.
