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
