Add another study to the pile of research raising alarms about a looming climate disaster.
Scientists have been closely watching the Atlantic Meridional Overturning Circulation (AMOC) for years. In April, two studies noted the critical current is in danger of weakening or even collapsing due to climate change, which could impact the climate and weather for hundreds of millions of people.
If you missed those studies, you might still know the current from the movie “The Day After Tomorrow,” which took quite a few liberties in its depiction of what would happen if the current suddenly collapsed due to climate change.
Now, a new study released April 29 says the AMOC has changed rapidly in the past, due to “violent volcanic eruptions” that eventually cooled the entire planet.
