A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster ...
A crucial system of ocean currents may already be on course to collapse with devastating implications for sea level rise global weather — leading temperatures to plunge dramatically in some ...
They include ice melt that could cause severe sea-level rise and the collapse of a crucial ocean current that governs how heat cycles in the Atlantic Ocean. Venezuela lost its final glacier this year.
It found within Great Britain an average temperature drop of 3.4 °C (6.1 °F) after the effect of warming was subtracted from collapse-induced cooling. A collapse of the AMOC would also lower rainfall during the growing season by around 123 mm (4.8 in), which would in turn reduce the area of land suitable for arable farming from 32% to 7%.

As the result, the study estimated the risk of an abrupt cooling event over Europe caused by the collapse of the current at 36.4%, which is lower than the 45.5% chance estimated by the previous generation of models [81] In 2022, a paper suggested that previous disruption of subpolar gyre was connected to the Little Ice Age.
A system of ocean currents that transports heat northward across the North Atlantic could collapse by mid-century, according to a new study, and scientists have said before that such a collapse ...
An ocean current is generated by the forces such as breaking waves, temperature and salinity differences, wind, Coriolis effect, and tides caused by the gravitational pull of celestial bodies. In addition, the physical properties in a pycnocline driven by density gradients also affect the flows and vertical profiles in the ocean. These changes ...
