Extremely precise chronologies of carefully selected speleothems from sites in the Northern Hemisphere and the tropics allow to trace the spatial evolution of the abrupt onset of the Younger Dryas stadial some 12,900 years ago adding support to the hypothesis that the Northern Hemisphere has been leading the Southern Hemisphere during climate coolings, while the trigger for the end of this stadial appears to have resided in either the tropics and/or the Southern Hemisphere.
