Through a variety of mechanisms, anthropogenic climate change is worsening wildfires. For instance, warm winter temperatures were a key factor in British Columbia’s apalling mountain pine beetle epidemic, and trees killed by the beetles may be more susceptible to fire. More directly, high temperatures dry out forests and raise fire risks.
Page 44 of the divestment brief summarizes some of the research on climate change and wildfires.
Fires also contribute to the worsening severity of climate change, both by releasing large amounts of carbon dioxide and by producing dark soot which absorbs energy from sunlight.
