A long-term study of the health of Canadian children has found that exposure to ozone (O 3 ) at birth was associated with an 82% increased risk of developing asthma by age three. An 82% higher risk of developing asthma was associated with each 10 parts per billion, or ppb increase in exposure to ozone at birth.

The loss of ice from West Antarctica is estimated to have increased by 60% in the decade to 2006, and by 140% from the Antarctic Peninsula in the same period. The hole in the ozone layer has had a cooling effect on Antarctica, and is partly responsible for masking expected warming on the continent. meters above the 1990 level by 2100.
