Changes in ocean 'conveyor belt' foretold abrupt climate changes by four centuries
"In the Atlantic Ocean, a giant 'conveyor belt' carries warm waters from the tropics into the North Atlantic, where they cool and sink and then return southwards in the deep ocean. This circulation pattern is an important player in the global climate. Evidence increasingly suggests that this system is slowing down, and some scientists fear it could have major effects. A new study published in Nature Communications provides insight into how quickly such changes could take effect if the system continues weakening."
