Abstract

Ocean circulation redistributes Earth's energy and water masses and
influences global climate. Under historical greenhouse warming, regional
ocean currents show diverse tendencies, but whether there is an emerging
trend of the global mean ocean circulation system is not yet clear. Here, we
show a statistically significant increasing trend in the globally integrated
oceanic kinetic energy since the early 1990s, indicating a substantial
acceleration of global mean ocean circulation. The increasing trend in
kinetic energy is particularly prominent in the global tropical oceans,
reaching depths of thousands of meters. The deep-reaching acceleration of
the ocean circulation is mainly induced by a planetary intensification of
surface winds since the early 1990s. Although possibly influenced by wind
changes associated with the onset of a negative Pacific decadal oscillation
since the late 1990s, the recent acceleration is far larger than that
associated with natural variability, suggesting that it is principally part
of a long-term trend.
