Canada's Environment Minister Peter Kent lists "ozone opening and closing over the poles" as evidence that CO2 is overheating the planet?

Hurricane Sandy another sign of danger of global warming, Peter Kent says

“Droughts, floods, the diminishing ice cap, ozone opening and closing over the poles — you don’t have to convince me that climate change is a very real and present danger and I think that we need to address it. We need to address it by bringing the rest of the world on board to do something about it.”
