We all learn something new every day. There was a time that was a good thing. Times change.
Yesterday I learned of "Arctic cyclones." I'd always thought of cyclones or hurricanes as warm-temperature events, fronts moving out of the tropics sort of things. Turns out we're now getting them up in the Arctic too.
The results of a 2008 mega-study of Arctic ice were released in Winnipeg yesterday. A team ofr 370 scientists from around the world spent 2008 up in the Arctic taking a close look at conditions and that led to a report about the "Circumpolar Flaw Lead System."
Speaking to a symposium yesterday, professor David Barber didn't pull any punches. The Arctic ecosystem, he said, is worse than we'd thought and is in fact under threat of collapse. We've known for years that Arctic sea ice is becoming a seasonal thing and is receding but we never really grasped just what that meant to the ecosystem. It does everything from releasing toxic contaminants into the sea to generating cyclones that further hasten the break up of sea ice to drawing the jet stream - and warming air - steadily further north. Marine life is being impacted by the toxins and the disappearance of the ice cap. Orca, once held at bay by the ice, are now spreading into the Arctic to prey on the once protected creatures. Lovely, just lovely.
Oh well, with a government headed by a petty tyrant with a stooge like Prentice for EnviroMin I'm sure we have nothing to worry about.
