Marine Scientists Issue Monaco Declaration Calling for Immediate Action to Reduce Ocean Acidification

Green Car Congress

Green areas indicate waters supersaturated with aragonite carbonate and favoring shell formation, with darker color indicating more favorable conditions. Red areas are those where waters are under-saturated in aragonite and so hostile to shell formation by marine organisms, with darker color indicating greater under-saturation.

Researchers Find That Stratospheric Ozone Depletion Reduces Southern Ocean Carbon Uptake

Green Car Congress

Researchers in France have found that ozone depletion above Antarctica has significantly reduced the Southern Ocean’s ability to absorb atmospheric CO 2 and has also accelerated acidification of southern polar waters, despite lesser CO 2 uptake. The results revealed that, between 1987 and 2004, around 2.3 Lenton, A., Tagliabue, and J.
