A vital system of ocean currents could soon collapse
A critical system of ocean currents could collapse much sooner than expected as a result of the deepening climate emergency, according to the findings of a new study, potentially wreaking havoc across the globe.
Peer-reviewed analysis published Tuesday in Nature Communications estimated that the Atlantic Meridional Overturning Circulation (AMOC), of which the Gulf Stream is a part, could collapse around the middle of the century — or even as early as 2025.
Climate scientists who were not involved in the study acknowledged that the current has become less stable, but urged some caution in parsing the findings of the research.
The AMOC acts like a conveyor belt of currents carrying warm waters from north to south and back in a long and relatively slow cycle within the Atlantic Ocean. The circulation also carries nutrients necessary to sustain ocean life.
A better known section of this circulation is the Gulf Stream, a wind-driven current that keeps major parts of Europe and the east coast of Florida warm, according to the National Oceanic and Atmospheric Administration.
For one, the NOAA says England would have a "much colder climate" if not for the warm waters of the Gulf Stream.
The projected collapse of the AMOC is seen as a "major concern" because it is recognized as one of the most important tipping elements in the Earth's climate system.
