More commentary on a recent @NatureComms paper hinting at a future decline of the #AMOC. How though does this work sit alongside findings of related variability e.g. #AMO | Science | AAAS https://t.co/IymmGb7o7K https://t.co/uL4GvyTGtJ https://t.co/xQhMYu

Have you read this? https://t.co/uiGjCpvlTm Suggests the artifact in the graph you posted isn't real; just a data anomaly caused by the statistical methods used.

@Daniele_V94 👁️ però a definire una volta per tutte la AMO come un ciclo di variabilità interna. Ci sono ancora parecchie incertezze a riguardo, e non è da escludere che una componente dell'oscillazione sia forzata.▶️ https://t.co/qKKh4o5FoG / https://t.co

@Lacertko IMHO mostly a) GHGs over decades + d) ENSO over months. #EndFossilFuels https://t.co/Yc6IcBYFpI

@freddie07068768 @RogTallbloke I understand it to be a unit less index. And Michael Mann, et al claim it is indistinguishable from noise! Their thinking seems to be that if their models don't reproduce it, it must not exist! Backwards from normal scienc

@Daniel_Marbella 1. True 2. How does back radiation from CO2 drive SSTs? It does not penetrate more than a few mm? 3. It's not been studied heavily due to the focus on CO2. Michael Mann has tried to erase the AMO, which says all you need to know: https://
