The entire province is on fire. It has barely rained in the southern half of the province since April. It is climate change.

The entirety of BC is not currently on fire (obviously). And if "BC is on fire" right now, then it would also be "on fire" when there is one single forest fire burning in the province.
warmer air holds more moisture, pulling it from the ground and holding it longer. Explains drier conditions and more extreme rainfalls when they do finally occur
