evidence: Roughly half of all wildfires in Canada are caused by lightning; due to climate change, lightning-caused fires are happening more frequently, and lightning strikes are expected to double by the end of the century.[18][30][31] In terms of wildfire acreage, lightning-caused fires account for about 85% of land burned.[32][33] Lightning-caused fires often happen in clusters in remote locations.[34] The other half of wildfires in Canada are human-caused, often unintentionally sparked[35][36] by things such as discarded cigarette butts,[32] abandoned smouldering campfires,[37] sparks from braking trains, off road vehicles, and land clearing activities.[36] While false claims of arson gained traction on social media, arson is generally a minor cause of wildfires in Canada.[38][39] [...] - ^ a b "Canada wildfires spark 'ecoterrorist' conspiracy theory".
