The rapid melting of Antarctic ice poses a threat to halt deep ocean currents, which would have a negative impact on the climate, the movement of fresh water and oxygen, as well as nutrients necessary for life, for centuries, as per claims from the scientific community, reported by DW. Deep ocean currents surrounding Antarctica may slow by more than 40% over the course of the next 30 years, according to a recent study that was published in the journal Nature on Wednesday. According to the study, in a high-emission scenario, the "overturning circulation" of the ocean's deep waters will reduce by 40% by 2050, with consequences lasting "for generations to come."
