Cumulative wildfire casualties worldwide 1911-2021
Between 1911 and August 2021, roughly 17 million people were affected by wildfires worldwide. Wildfires are unplanned fires occurring in forested areas and most commonly caused by human activity or lightning strikes. Dry conditions worsened by global warming have increased the risk of uncontrollable wildfires for multiple regions such as Australia, the Mediterranean, and Western United States. The death toll due to wildfires stands at 4,545 people, with the 2021 Kabylia fires in Algeria the most recent in a list of most severe wildfires by number of fatalities.
