Atmospheric scientists are analyzing data from weather balloons and satellites for clues to how the ozone will fare when sunlight — a third factor in ozone loss — returns to the Arctic.

To determine whether declining pollutants deserve credit for the recovery, the researchers used a 3D atmospheric model to separate the effects of the chemicals from those of weather, which can affect ozone loss through winds and temperature, and volcanic eruptions, which deplete ozone by pumping sulfate particles into the upper atmosphere.

They fear that similar aerosol already in the northern stratosphere, which came from the eruption of Mount Pinatubo in the Philippines in June 1991, may cause a dramatic loss of ozone in the northern hemisphere next February or March.

We knew that it would save us from large ozone loss «in the future», but in fact we are already past the point when things would have become noticeably worse,» lead author Professor Martyn Chipperfield, from the School of Earth & Environment at the University of Leeds, said in a press release.

That growth of sea ice could have potentially been caused by the influx of freshwater as glaciers on land melted, or from changes in the winds that whip around the continent (changes that could be linked to warming or the loss of ozone high in the atmosphere).
