This variability in the ozone loss is to be contrasted with the Antarctic, where nearly complete ozone loss has taken place in almost all winters since the late 1980s. This difference is linked to the Arctic warmer winter conditions. The concern is that the Arctic appears to be moving into Antarctic-like conditions which will result in an increase in UV radiation levels that will have consequences on human health in northern hemisphere countries.
Un tendance inquiétante est que la situation dans l’Arctique semble se rapprocher de celle de l’Antarctique, ce qui se traduira par une augmentation des niveaux de rayonnement UV, avec des conséquences pour la santé humaine dans les pays de l’hémisphère nord.
