Our second video explains the science and relevance of studying Antarctic southern ocean tipping points: 

1. Antarctica is currently protected from the warmest waters of the Southern Ocean by a shield of cold water that almost completely surrounds the ice sheet; 

2. The protective ring of cold water exists due to large-scale wind patterns and sea-ice processes; 

3. Future changes in these processes could push the system past a ‘tipping point’ leading to higher melting and raising sea level. 

Note that you can choose subtitles in English, German, French and Norwegian!

Enjoy!
