What Could Happen to the Ocean’s Carbon If AMOC Collapses
Mass glacier melting may have led this influential ocean current system to collapse at the end of the last ice age. A pair of modeling studies examines how such a collapse could affect dissolved inorganic carbon and carbon isotopes in Earth’s oceans.
