| Zusammenfassung |
| In the Pliocene Model Intercomparison Project (PlioMIP), eight
state-of-the-art coupled climate models have simulated the mid-Pliocene warm
period (mPWP, 3.264 to 3.025 Ma). Here, we compare the Atlantic Meridional
Overturning Circulation (AMOC), northward ocean heat transport and ocean
stratification simulated with these models. None of the models participating
in PlioMIP simulates a strong mid-Pliocene AMOC as suggested by earlier
proxy studies. Rather, there is no consistent increase in AMOC maximum among
the PlioMIP models. The only consistent change in AMOC is a shoaling of the
overturning cell in the Atlantic, and a reduced influence of North Atlantic
Deep Water (NADW) at depth in the basin. Furthermore, the simulated
mid-Pliocene Atlantic northward heat transport is similar to the
pre-industrial. These simulations demonstrate that the reconstructed
high-latitude mid-Pliocene warming can not be explained as a direct response to
an intensification of AMOC and concomitant increase in northward ocean heat
transport by the Atlantic. |
