Analysis of sea surface temperature (SST) observations suggests a pan-oceanic interaction between the tropical Pacific anti the Atlantic Ocean at multidecadal time scales, such that periods of anomalously high SSTs in the tropical Pacific are followed by a basin-wide SST dipole in the Atlantic Ocean with a time delay of a few decades. The SST anomaly structure: in the Atlantic Ocean is reminscent of variations in the North Atlantic thermohaline circulation. The two ocean basins are linked through an atmosphrric bridge involving anomalous fresh water fluxes. Based on the observational findings, the Atlantic thermohaline circulation may strengthen during the next decades in response to the strong decades-long increase in tropical Pacific SST, which will have strong impacts on the climates of North America and Europe through changes in the North Atlantic Oscillation (NAO).
