Here’s the latest on AMOC from reputable sources and recent assessments.
Most recent headlines suggest ongoing debate about AMOC stability. Some analyses imply the risk of weakening or potential tipping points, while other studies argue the collapse within this century remains unlikely under current warming trajectories. This reflects a split in interpretation across recent papers and media coverage.[4][6]
A strong theme is that policy actions to reduce carbon emissions could influence AMOC trajectories, with higher emissions scenarios associated with greater probabilities of disruption in climate model projections, though exact timing remains uncertain.[1][5]
Key caveats: observational data on AMOC strength are limited in space and time, so models must be interpreted with caution. Several expert briefs emphasize that even without a full collapse, substantial weakening could still alter regional climate patterns and rainfall in Europe and the tropics.[9][1]
For regional implications in Europe and North America, predictions range from milder warming in some areas to potential shifts in precipitation and storm tracks if AMOC weakens, but definitive outcomes depend on future emissions and ice-sheet behavior.[3][5]
Notable counterpoints caution that the century-scale probability of a complete AMOC collapse remains low in some model studies, though these studies also stress the importance of continued monitoring and research because small changes can have outsized regional effects.[6][4]

If you’d like, I can pull the most recent peer-reviewed papers or summarize a specific study in detail, and I can also present a concise timeline of major AMOC-related findings from 2023–2026 with inline citations.
A new letter signed by 42 climate scientists warns that the Atlantic Meridional Overturning Circulation (AMOC) pattern may collapse much sooner than expected, with devastating consequences for the global climate. The risk of AMOC collapsing is much higher than previously estimated by the IPCC, according to these scientists. The latest IPCC report

www.theguardian.comAt the end of October, 42 climate scientists sent an open letter to the Nordic Council of Ministers, urging them to draw attention to the major ocean circulation change in the Atlantic. “A string of scientific studies in the past few years suggests that this risk has so far been greatly underestimated”, they write.
