The Guardian and the Times in England both feature the beautiful blue,
colour-enhanced, photograph of the enlarged ozone hole over the Antarctic.
Although the story comes from Nasa I cannot see that US media like CNN or
the International Herald Tribune, give it such prominence. I am not sure if
this is complacency about the problem extending to the northern hemisphere.
The scientists seem vague in their reassurance that large findings for the
size of the ozone hole will continue till 2010, but that the surge this
year is for random causes, and supposedly part of natural variation. CFC's
were banned in 1987 but continue breaking down ozone for decades.
There is little room for greater tolerance in the margins of these
predictions. Economic production is nearing its global rate-limiting steps.
