While we’re at it, it would also be important to consider what if any impacts the recent i.e last 30 years of commercial timber management regimes in the far north has played here in terms of broad ecosystem impacts. Prior to the mid 80s nobody was cutting wood that far north into the Canadian Shield, that’s changed. Look at google earth, they’re cutting wood right up into the sub arctic. Point is, there are so many factors to consider. I don’t agree with attributing this to CC with blanket statements, as many have done. Who knows, maybe CC is the dominant driver, but we just can’t say that with certainty right now, there are too many other variables to consider.
