I live in British Columbia and for the past 3 summers have had to spend at least all of August indoors with doors and windows sealed shut due to the dangerous levels of particulates in the air. I am already experiencing it.
More or less. The fires are caused mostly by lightening and dry winds (some human caused too) by also contributed to by a lot of fuel from overly wet spring followed by dry hot summer.
A small increase in temperature results in a significant increase in lightening which is the big worry.
