Although most attempts have been focused on high-latitude climate feedbacks, no consensus has been reached in explaining the forcing mechanism of this dramatic climate change. Here we present a key low-latitude climate record, the high-resolution Asian monsoon precipitation variability for the past five million years, reconstructed from South China Sea sediments. Our results, with supporting evidence from other records, indicate significant mid-Pliocene Asian monsoon intensification, preceding the initiation of NHG at ca. 2.7 Ma ago. This 1.4-million-year-long monsoon intensification probably enhanced monsoon-induced Asian continental erosion and chemical weathering and in the process left fingerprints in marine calcium isotopes. Furthermore, increased rock weathering and/or organic carbon burial probably lowered the contemporary atmospheric CO2 and may have triggered the NHG onset.","pubRank":"1"},{"author":{"name":"Zhang, Y.G., J.
