Huge hole opens in Arctic ozone layer Margaret Munro, Postmedia
NewsPublished: Sunday, October 02, 2011 A massive Arctic ozone
hole opened up over the Northern Hemisphere for the first time
this year, an international research team reported Sunday. The
hole covered two million square kilometres - about twice the
size of Ontario - and allowed high levels of harmful ultraviolet
radiation to hit large swaths of northern Canada, Europe and
Russia this spring, the 29 scientists say. The discovery of the
"unprecedented" hole comes as the Canadian government is moving
to reduce staff in what Environment Minister Peter Kent calls
the "streamlining" of its ozone monitoring network. View of the
