“Vital Atlantic Ocean currents are unlikely to completely collapse this century…

The latest study, published in the journal Nature, used 34 state-of-the-art climate models to assess the Amoc. The researchers used extreme conditions – a quadrupling of carbon dioxide levels or a huge influx of meltwater into the North Atlantic – so that the changes in the modelled ocean currents were clear.

They found that while the Amoc slowed by between 20% and 80% this century, it did not collapse completely in any of the models. This was because winds in the Southern Ocean continued to draw water up to the surface. Balancing this, to the scientists’ surprise, were new downwelling areas in the Pacific and Indian oceans, but they were not strong enough to wholly compensate for the slowing of the Amoc, leaving it significantly weakened.”
