Summary:
The oceans lock away atmospheric carbon dioxide, but a 'leak' in the Southern Ocean brings the greenhouse gas back into the atmosphere. An international research team looked at minute nitrogen concentrations embedded in diatoms, forams and corals to identify an increase in Southern Ocean upwelling during the past 11,000 years, which could explain the otherwise mysterious warmth of the Holocene that allowed human populations to flourish.
