A recent study casts doubt on evidence of a weakening of the Atlantic Meridional Overturning Circulation (AMOC), one of the most important ocean systems affecting Europe’s climate.

Scientists say the previously documented weakening of the Florida Current may be due to changes in the geomagnetic field rather than global warming.
The Florida Current, part of the AMOC, has been measured using submarine cables since 1982. Previously, the current was thought to lose 30,000 cubic meters per second every ten years. However, the new study suggests that changes in the magnetic field may reduce this to 0.1 superdrup, which is within the margin of error.
