Twenty-two years of continuous AMOC observation

node

Across the record from April 2004 to January 2023 the RAPID array gives a mean overturning maximum of 17.0 Sv with a standard deviation of 2.8 Sv and a weakening of 1.0 [0.4–1.6] Sv per decade. Analysis of signal against noise in the same record suggests the observed trend will not become clearly distinguishable from natural variability until the 2040s on one threshold and the 2060s on a stricter one. A separate analysis of the same period reports a steeper decline of 2.6 ± 0.7 Sv per decade, which is a reminder that the number depends on the method as well as on the ocean.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
