Catastrophic drought in the Afro-Asian monsoon region during Heinrich Event 1
Between 18,000 and 15,000 years ago, large amounts of ice and meltwater entered the North Atlantic during Heinrich Stadial 1. This caused substantial regional cooling, but major climatic impacts also occurred in the tropics. Here we demonstrate that the height of this stadial, ca. 17-16,000 years ag...
