I'm not sure you can really find a trend here, keep in mind reporting is probably really spotty in earlier years. The more people around to see it, the more reports you are going to get. In 1982 you may have thought the world was going to end. We've had a few years recently with more reported, but you can't really call that a trend either, as 1980-1982 was worse. At a quick check I don't see how you could attribute that to climate change, just looking at Alberta numbers.
