[Ag-umwelt] 25 Jahre Ozonloch

["Dr. Volker Jaenisch" <volker.jaenisch AT inqbus.de>]

Ahoi!

Das Ozonloch wird 25!

"""
It was perceived as one of the greatest environmental threats of the 
late-20th century. Twenty-five years ago this month, a hole in the ozone 
layer was detected high in the atmosphere over the frozen wastes of 
Antarctica; scientists warned it might spread to other parts of the 
world, leading to dangerous increases in cancer-causing radiation from 
the Sun.
...
More than 20 years after the Montreal Protocol, there are signs that the 
ozone layer is beginning to recover. It could still take decades for it 
to return to the state it was in 50 years ago, but had it not been for 
three scientists who persevered with a seemingly irrelevant, long-term 
experiment, it would take longer still.
