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 ...
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.
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 ...
Even if initiated in the near future, the circulation's collapse is unlikely to be complete until close to 2300, [94] Similarly, impacts such as the reduction in precipitation in the Southern Hemisphere, with a corresponding increase in the North, or a decline of fisheries in the Southern Ocean with a potential collapse of certain marine ...
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%. The net value of British farming would decline by around £346 million per year – over 10% of its value in 2020.
Once triggered, the collapse of the current would most likely take 10 years from start to end, with a range between 5 and 50 years. The loss of this convection is estimated to lower the global temperature by up to 0.5 degrees, while the average temperature in certain regions of the North Atlantic decreases by around 3 degrees .
The collapse of critical ocean circulation could bring major droughts and freezing temperatures across Europe. ... is a system of deep ocean currents that acts as the Earth’s central heating system.
