Variations of the Atlantic meridional overturning circulation in control and transient simulations of the last millennium

Variations of the Atlantic meridional overturning circulation in control and transient simulations of the last millennium

... In agreement with this speculative statement, the impact of the time-varying forcing on the AMOC is not linear. For the volcanic forcing, we find no significant response of the overturning circulation at all, in contrast ...
