How does burning fossil fuels threaten Antarctic marine life?

This experiment demonstrates the link between increasing carbon dioxide levels and ocean acidification and freshening oceans. Freshwater and more acidic water in the oceans make life harder for Antarctica’s marine animals.

The experiment and video were made by Nick Barrett. Nick is a PhD student at the University of Cambridge Earth Science Department and The British Antarctic Survey investigating the resistance of Antarctic marine species to predicted freshening and lower salinity in the Southern Ocean.
