North American wildfires

Wildfires in the US regularly appear on our TV news, so much so that the British public must have grown blasé about them. (However, this photo of burning forests in Montana competing with the Aurora must be nearly unique.) Much more exceptional is the continuing conflagration in Canada which is worrying scientists and not only in the Dominion. Considering the implications, it has received scant attention here. Not only must it be a symptom of global warming, it could be adding to ice melt as its fall-out increases absorption of heat from the sun.
