Abstract
Previous work has shown that near-surface ocean temperature off southern California increased during the 1970s and 1980s. This increase is probably not due to anthropogenic effects since measurements at three California coastal stations show that decadal and longer sea surface warming and cooling has also occurred earlier this century as part of a “natural” decadal and longer varying climate signal. The changes are mainly driven remotely by decadal and longer weakening and strengthening of the equatorial Pacific trade winds, which lower and raise the thermocline and affect ecosystems along thousands of kilometers of the western coastline of the Americas.Keywords
