The Atlantic Ocean moves heat northward on a planetary scale. That circulation is now slowing. Observations show a 15 percent decline in heat transport linked to AMOC weakening. The core seed is temperature, and the risk is a hemispheric redistribution that cools Europe while warming the tropics.
💡 Frequently Asked Questions (FAQ)
- Q: What is AMOC and why does it matter for temperature?
- A: AMOC is the Atlantic Meridional Overturning Circulation that moves heat northward. Its weakening reduces heat transport to Europe and redistributes temperature globally.
- Q: How much has Atlantic heat transport declined?
- A: Recent observations show about a 15 percent decline in heat transport linked to AMOC weakening.
- Q: Could Europe return to a Little Ice Age by 2060?
- A: Models warn AMOC slowdown could cool Europe significantly, with some projections suggesting Little Ice Age-like conditions before 2060 if the decline continues.
