A vital system of ocean currents could collapse within a few decades if the world continues to pump out planet-heating pollution, scientists are warning – an event that would be catastrophic for global weather and ‘affect every person on the planet.’
It has happened before. More than 12,000 years ago, rapid glacier melt caused the AMOC to shut down, leading to huge Northern Hemisphere temperature fluctuations of 10 to 15 degrees Celsius (18 to 27 Fahrenheit) within a decade.
What caused the rapid glacier melt before and how did the planet bounce back. Knowing this could held expedite the “fast and effective measures to cut planet-heating pollution to zero, to reduce global temperatures and slow melting in the Arctic” that the report has called for.
