The behaviour of the Atlantic meridional overturning circulation (MOC) during the Last Glacial Maximum (LGM), about 21 kyr ago, remains uncertain, with different lines of evidence arguing for either no change or a sharp reduction. These authors present an analysis of flow-sensitive protactinium and thorium isotopes from the North and South Atlantic oceans, showing that the previously contradictory results can be integrated in a new framework supporting a reversed Atlantic MOC at the LGM.
