Changing Seas
The Fate of Carbon
Season 9
Episode 903
For millennia, the exchange of CO2 between the oceans and atmosphere has been in balance. Now, with more anthropogenic carbon-dioxide in the atmosphere, the oceans are taking up more CO2 as well. This negatively impacts sensitive ecosystems through a process called ocean acidification, and scientists worry how changes to the ocean environment will affect the way carbon is cycled through the seas.
