The Arctic and the Ozone Layer (HD Version)

The Arctic region, around the North Pole, is an important indicator of the impacts of industrial and human activities, both at the surface level and in the atmosphere. The rapid warming of the region has attracted considerable scientific attention.
Besides the well known phenomenon of global warming occurring in our lower atmosphere, another atmospheric phenomenon had been taking place over the Arctic. Recent record low ozone values in the stratosphere have led scientists to take a closer look at the links between the changing climate and ozone distribution; changes that may undermine the recovery of the Ozone layer predicted to occur in a few decades.
