Short summary
Eastern boundary upwelling systems (EBUSs) are crucial for resources, but climate change poses uncertainties for their future. To assess global warming's impact, we examine Andrew Bakun's 1990 hypothesis of intensified upwelling using deseasonalized sea surface temperature data. A new index, αUI, normalizes upwelling trends against non-upwelling processes, confirming intensification in all EBUSs and supporting Bakun's hypothesis.
