No Consistent Simulated Trends in the Atlantic Meridional Overturning Circulation for the Past 6,000 Years
The Atlantic Meridional Overturning Circulation (AMOC) is a key feature of the North Atlantic with global ocean impacts. The AMOC's response to past changes in forcings during the Holocene provides important context for the coming centuries. Here, we investigate AMOC trends using an emerging se...
