The study shows that there was a period when the flow of deep waters in the Atlantic was reversed. The results are relevant for the near future since similar changes are expected to occur in the course of climate warming over the next 100 years. The Atlantic Ocean circulation (termed meridional overturning circulation, MOC) is an important component of the climate…
