Climate change isn't the direct cause here but a contributing factor. Temperatures like seen there in the last couple of days will dry things out to the point that and extremely sensitive environment develops, a single cigarette tossed un-carefully has the potential to cause something like this.

Now obviously those things will also happen during 'normal' times (for whatever that means), but as these things happen more often there will be more opportunities for consequences such as these to materialize.

Let's hope it does not spread by wind because that whole region is a tinderbox right now. Friends in BC say they are doing well all things considered but would love for normality to be restored and were acutely aware of the fire risks involved. That under those circumstances a fire did in fact happen should give everybody pause, Canadians are not exactly stupid when it comes to fire prevention.
