This article provides a comprehensive, accessible overview of the Atlantic Meridional Overturning Circulation (AMOC), explaining the role of this major ocean current system, why it is weakening due to climate change, and the implications of its potential collapse.
The article ends by describing the collapse of this current system as a tipping point and warns of the irreversibility of such an event.
Ensure students are well-versed in climate change impacts, such as ocean warming and glacial melt.
Classroom Implementation:
Have students read this article in preparation for a discussion about the destabilization of the AMOC and its resulting impacts.
Before reading, use a world map to show students the position of London and Quebec City at similar latitudes but very different climates.
After reading, have students construct a systems diagram showing how the AMOC connects the atmosphere, ocean, ice, and land, and label the feedback loops that could cause destabilization.
