Short summary
Wildfires are the largest contributor to atmospheric pollution from all fires globally, with major consequences for health and air quality. This study examines the main contributing factors governing wildfire emissions during the 20th and 21st centuries using simulations with climate and ecosystem models. Contrary to common perception, climate change is only one of several important factors, but population change, urbanization and changing atmospheric CO2 levels are at least equally important.
