Summary

The Atlantic meridional overturning circulation (AMOC) has long been implicated in rapid climate changes during the most recent ice age. However, convincing observational evidence from the deep ocean has remained limited. On page 470 of this issue, Henry et al. (1) present two independent records from a well-dated, high-resolution sediment core from Bermuda Rise in the North Atlantic (see the figure) that may be the smoking gun that paleoceanographers have been looking for.
