Weakening of the South Asian summer monsoon linked to interhemispheric ice-sheet growth since 12 Ma

The εNd record from the IODP Exp. 359 Site U1467 in the northern Indian Ocean, along with climate modeling, reveals a two-step weakening of the South Asian summer monsoon (SASM) wind since 12 Ma. The SASM evolution was mainly caused by interhemispheric ice-sheet growth since the Middle Miocene.
