Why Are Massive Ocean Currents Slowing Down?

A new study makes a dire prediction about the effects of Antarctic meltwater on the deep ocean currents and the resulting impact on marine ecosystems. Scientia Professor and Academy Fellow Professor Matthew England of UNSW Sydney, and Dr Adele Morrison, DECRA Research Fellow at the ANU, explain the results of their landmark paper, published today in Nature: Is the Southern Ocean about to have its own ‘Day After Tomorrow’ moment? This video, fact-checked by Australian Academy of Science expert Fellows, explains how these changes would profoundly alter the ocean’s overturning of heat, freshwater, oxygen, carbon and nutrients, with impacts felt throughout the global ocean for centuries to come.
