A recent study led by WHOI and UCL shows the deep ocean in the North Atlantic has crucially reduced climate swings over the past 1,000 years.

The research indicates that the deep ocean has consistently transferred surface climate changes, preventing them from becoming significantly worse.

The deep ocean cooled during the Medieval Climate Anomaly and gave heat back to the atmosphere during the Little Ice Age.

The study highlights the ocean's important role in mitigating global warming by absorbing and storing excess heat.

The research provides valuable data on deep ocean temperature and reduces reliance on climate models.

Concerns have been raised about the potential slowdown of the Atlantic Meridional Ocean Circulation (AMOC), which could affect future heat transfer and storage.

The study was funded by the National Science Foundation, the Edna McConnell Clark Foundation Fund, and the WHOI Postdoctoral Scholar Program.
