I live in Canada, and considering the number of articles in recent years which have listed the impacts of global warming on the country, it's looking like a huge win. Even if only some of the permafrost melts, this is a huge increase in arable land and will allow as much as a doubling of agricultural output. Access to additional fresh water also increases significantly, which is notable given how much hoopla is made about water as an ever-more scarce resource. Increasing population density further north, and making the north actually productive. Better access to natural resources in the north, including mining and gas/oil extraction in the arctic. Levying fees on ships going eventually year round through the northwest passage. The boon global warming, if real, will bring to this surpasses by an order of magnitude anything its politicians could bring about. So yes, please, bring it on!
