• The Atlantic Meridional Overturning Circulation (AMOC) is at risk of collapse due to global warming and meltwater from Greenland.
• A collapse of the AMOC could release up to 640 billion tonnes of carbon dioxide from the Southern Ocean.
• The study emphasizes the urgent need to mitigate climate change to prevent AMOC collapse and further global warming.
AMOC collapse threatens major carbon dioxide release
The Atlantic Meridional Overturning Circulation (AMOC), a vital ocean current system, is in danger of collapsing due to the impacts of global warming and the influx of fresh meltwater from the Greenland ice sheet.
