Short summary
Transient climate models simulate warming over the past 5000 years due to a 20 ppm CO2 rise, yet paleo-proxies indicate cooling. In this study, we examine the mid-latitude North Atlantic, where model-data mismatch is largest. Our analysis links Late Holocene cooling to increased zonal SST (Sea Surface Temperature) asymmetry, likely from basin-scale reorganization of inter-gyre circulation. Transient models, however, do not to capture this spatial pattern and associated circulation changes.
