Linking surface air temperature changes to a slowing AMOC in a multimodel approach

Abstrac: The Atlantic Meridional Overturning Circulation (AMOC) is a key regulator of global climate, and its potential slowdown due to anthropogenic forcing poses significant risks to climate stability. This study analyzes global and regional surface air temperature (SAT) changes associated with AMOC variability using an ensemble of CMIP6 climate models. We investigate regional warming patterns over the Atlantic and Arctic in relation to AMOC fluctuations and examine how these patterns evolve under different global warming levels. While our analysis identifies correlations between AMOC variability and SAT changes, it does not establish concrete early-warning signals or tipping points but lays the groundwork for future research. Future work will focus on assessing potential \textbf{precursors of AMOC weakening} through detailed lagged correlation and trend analyses.
