Ocean currents are getting faster

'The change is driven by global warming and wind.


Ocean currents are moving faster today than they did two decades ago.

New research, published today (Feb. 6) in the journal Science Advances, finds that this acceleration is occurring around the globe, with the most noticeable effects in the tropical latitudes. The enhanced speed isn’t just at the ocean’s surface, but is occurring as deep as 6,560 feet (2,000 meters).


“The magnitude and extent of the acceleration in ocean currents we detected throughout the global ocean and to 2000-meter (6,560 foot) depth was quite surprising," study co-author Janet Sprintall, an oceanographer at the Scripps Institution of Oceanography at the University of California, San Diego, said in a statement. "While we expected some response to the increased winds over the past two decades, that the acceleration was above and beyond that was an unexpected response that is likely due to global climate change."'
