In brief
Research published in the journal Science shows that wildfires causing major economic damage have increased by about 4.4 times since the 1980s, primarily driven by climate change and growing populations in fire-prone areas. The study identifies a worrying trend of more frequent catastrophic fires, particularly in Europe and North America, and emphasizes the importance of addressing underlying causes of fire disasters.
WASHINGTON — A new study indicates that significant wildfires across the globe are now occurring four times more often than in the 1980s, a trend attributed to human-induced climate change and increased human habitation near wildland areas.
Published in the journal Science, the study evaluates global wildfires not solely by acreage burned, but rather through the financial and human costs they inflict. Researchers uncovered a “climate-linked escalation of societally disastrous wildfires.”
Calum Cunningham, a pyrogeographer from the University of Tasmania in Australia and lead author of the study, noted the increasing frequency of the most economically devastating wildfires, which have quadrupled from approximately two per year in the 1980s to an average of nearly nine annually in recent years.
Over 43% of the most destructive fires of the past four decades have occurred in the last ten years, emphasizing the escalating crisis. Notable spikes in wildfire incidents correlating with extreme weather conditions were particularly evident from 2015 onward.
“It shows beyond a shadow of a doubt that we do have a major wildfire crisis on our hands,” Cunningham said. He highlighted the alarming rise in both the frequency and severity of these catastrophic blazes.
Current trends reveal Europe and North America are hotspots for economically damaging wildfires, especially in regions like the Mediterranean and the Western United States. These areas experience hot, dry conditions conducive to spontaneous ignition of forest fires, exacerbated by climate change.
The rising rates of deadly wildfires underscore a troubling shift: fires that cause at least ten fatalities have tripled in occurrences, representing a growing societal threat. This increase corresponds with events like the 2018 Paradise fire and the more recent Lahaina fire.
Researchers determined that emissions from coal, oil, and gas are driving the rise in extreme fire weather conditions that facilitate the ignition and active spread of these devastating wildfires. “This is an innovative study...and it mostly confirms common sense expectations,” said Jacob Bendix, a geography and environment professor.
As conditions continue to worsen, the imperative for effective wildfire management and preparation becomes increasingly critical. Experts warn that both awareness and strategic action are needed to confront the growing fire crisis exacerbated by climate change.
