In 2018, two separate investigations reached the same conclusion: the planet's circulatory system was weakening. The main set of ocean currents that carry immense amounts of water from tropical to northern seas would be slowing down due to the impact of climate change. He latest report from United Nations experts (the IPCC) published this year came to the same conclusion. But now, new work goes further, concluding that the so-called Atlantic Meridional Overturning Circulation (AMOC) will collapse in the coming decades if greenhouse gas emissions are not already reduced. . They even put a date on it, around 2057. However, other scientists maintain that there is not enough data to expect the collapse.
