It's pretty convenient for all the AGW alarmists to blame every somewhat weather-related event on global warming. Wildfires of immense size have been happening for as long as there have been forests in BC. And you'll note that a large portion of the recent fires are person-caused - which is kind of a stretch for blaming on global warming. 

Also, we've been suppressing natural fires for decades because of our (relatively new) firefighting efforts (and the real need to protect all the houses and infrastructure built in forested areas), which has allowed forest fuels to accumulate. Forest fires are often more intense that they used to be, because the more frequent, lower intensity fires have been suppressed.

I find the most enthusiastic converts to the global warming religion are those that dwell in urban centers, far away from forests and the natural world. They know not of what they speak, and are easily manipulated by the enviro industry.
