Short summary
This study shows that regional ocean warming can make the Gulf Stream appear to shift north more rapidly than it actually does. Temperature-based proxies, like the Gulf Stream North Wall, overestimate changes in its position. Methods based on sea surface height provide a more accurate view. These results help improve how we track changes in ocean currents and avoid misinterpreting signs of climate-related shifts.
