Choices made in the next decade will have long-term consequences for Antarctica and the globe, according to research published on 14 June by the journal Nature. The study explores how Antarctica and the Southern Ocean will change over the next 50 years, and how those changes will impact the rest of the globe. This was reported by CSIRO on 14 June.

Two scenarios are considered: one in which greenhouse gas emissions remain unchecked, and one in which strong action is taken to limit emissions and to manage increased human use of Antarctica.
