Climate change runs AMOC with Atlantic currents: studies

A system of Atlantic Ocean currents that regulates global weather is at its feeblest in 1,600 years, weakened partly by climate change, said researchers Wednesday, warning of trouble ahead. Two studies in the journal Nature concluded the system, dubbed the Atlantic Meridional Overturning Circulation (AMOC), is in decline -- validating a long-held scientific suspicion. The weakening, agreed the teams, was the result of melting sea ice, glaciers, and ice-shelves gushing freshwater -- less dense than salty ocean water -- into the North Atlantic.
