Graph: AMOC Index

Rahmstorf, Box, Feulner et al

The blue curves in the bottom panel show the AMOC index from Rahmstorf et al.,[1] namely the difference between subpolar gyre and Northern Hemisphere temperature anomalies. Proxy and instrumental data are decadally smoothed.

The AMOC index (blue curve) indicates a steady AMOC, with modest changes until the beginning of the twentieth century.
