Atlantic Ocean circulation is the weakest in at least 1,600 years, study finds – here s what that means for the climate By Jeff Berardelli Slowdown of current system could affect global climate
An influential current system in the Atlantic Ocean, which plays a vital role in redistributing heat throughout our planet s climate system, is now moving more slowly than it has in at least 1,600 years. That s the conclusion of a new study published in the journal Nature Geoscience from some of the world s leading experts in this field.
Scientists believe that part of this slowing is directly related to our warming climate, as melting ice alters the balance in northern waters. Its impact may be seen in storms, heat waves and sea-level rise. And it bolsters concerns that if humans are not able to limit warming, the system could eventually reach a tipping point, throwing global climate patterns into disarray.
Atlantic Meridional Overturning Circulation (AMOC) is an ocean current
It redistributes warm water throughout our planet s oceans
This also moves warm water from Gulf of Mexico to the North Atlantic
However, a new study finds it is weakening, which would disrupt our climate
Sea levels along the east coast could rise if AMOC slows and comes to a halt
Analysis of its strength shows it has weakened dramatically since the 1950s

A growing body of evidence suggests that a massive change is underway in the sensitive circulation system of the Atlantic Ocean, a group of scientists said Thursday.
The Atlantic meridional overturning circulation (AMOC), a system of currents that includes the Florida Current and the Gulf Stream, is now “in its weakest state in over a millennium,” these experts say. This has implications for everything from the climate of Europe to the rates of sea-level rise along the U.S. East Coast.
Although evidence of the system’s weakening has been published before, the new research cites 11 sources of “proxy” evidence of the circulation’s strength, including clues hidden in seafloor mud as well as patterns of ocean temperatures. The enormous flow has been directly measured only since 2004, too short a period to definitively establish a trend, which makes these indirect measures critical for understanding its behavior.
