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.
Those currents comprise half of the global thermohaline circulation that includes the flow of major ocean currents, the other half being the Southern Ocean overturning circulation. [ 2 ] The AMOC is composed of a northward flow of warm, more saline water in the Atlantic's upper layers and a southward, return flow of cold, salty, deep water.
When the fate of an ocean current system tops headlines during a historic heat wave, it’s a strange week for climate science. Climate collapse debate reinvigorated by study of Atlantic ocean ...
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.
There has been a suggestion that its collapse may occur between 1.7 °C (3.1 °F) and 3 °C (5.4 °F), but this estimate is much less certain than for many other tipping points. [16] The impacts of Southern Ocean overturning circulation collapse have also been less closely studied, though scientists expect them to unfold over multiple centuries.
