Canada losing its Arctic PEARL

Atmospheric scientist Pierre Fogal headed north in February to help check on Earth’s protective ozone layer high in the Arctic stratosphere.

But he spent much of his time on his knees dealing with burst water pipes and frozen sewer lines at Canada’s beleaguered Arctic research station.

Then this week, the electrical system malfunctioned, says Fogal, site manager for PEARL, the Polar Environmental Atmospheric Research Laboratory at the northern tip of Ellesmere Island.

The station, now limping along at half power and a chilly 10 C inside, is one of the world’s premier observatories for tracking the health of the Arctic atmosphere. The station houses millions of dollars worth of scientific equipment used to monitor the ozone layer, greenhouse gases and pollution swirling around the polar vortex. Continue reading →

Gaping hole opened in Arctic ozone layer

A huge Arctic ozone hole opened up over the Northern Hemisphere for the first time this year, an international research team reported Sunday.

The hole covered 2 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.

Environment Canada scientist David Tarasick, whose team played a key role in the report published Sunday in the journal Nature, is not allowed to discuss the discovery with the media. Continue reading →
