1 Wildfires can be caused by an accumulation of dead matter (leaves, twigs, and trees) that can create enough heat in some instances to spontaneously combust and ignite the surrounding area.  Lightning strikes the earth over 100,000 times a day. 10 to 20% of these lightning strikes can cause fire.
âWe donât need much of a spark to set off a fire that spreads long distances through the crowded, continuous forests,â Dr. Oliver said. And climate change, to which humans contribute, is heating up and drying out some â though not all â areas. Global studies of wildfire patterns are rare. But a paper published last year in the journal Ecosphere predicted that climate change would have an effect on wildfires that varies widely, especially in accordance with a given regionâs precipitation patterns.
