Researchers have found that building a dam across the Bering Strait could prevent the Atlantic Meridional Overturning Circulation (AMOC), a crucial current that is crucial to regulating climate in northern Europe. The dam could block the AMOC from reaching the Arctic Ocean, which could provide more time for the conveyor belt of currents. However, the study authors and other researchers caution that the effect is variable and further modeling studies are needed. If AMOC fails, it could raise the sea level along the northeast coast of North America by at least 1.6 feet (50 centimeters) and disrupt food production. The study suggests that with lower carbon dioxide (CO ) emissions and a minor weakening of AMOC, the closure of the Bered Strait could strengthen it and allow it to function as CO emissions rise, but it also found that with a weaker AMOC it would accelerate AMOC weakening.
