Study shows the world is far more ablaze now with damaging fires than in the 1980s
Earth's nastiest and costliest wildfires are blazing four times more often now than they did in the 1980s because of human-caused climate change and people moving closer to wildlands, a new study found.
A study in the journal Science looks at global wildfires, not by acres burned which is the most common measuring stick, but by the harder to calculate economic and human damage they cause. The study concluded there has been a "climate-linked escalation of societally disastrous wildfires."
A team of Australian, American and German fire scientists calculated the 200 most damaging fires since 1980 based on the percentage of damage to the country's Gross Domestic Product at the time, taking inflation into account. The frequency of these events has increased about 4.4 times from 1980 to 2023, said study lead author Calum Cunningham, a pyrogeographer at the Fire Centre at the University of Tasmania in Australia.
"It shows beyond a shadow of a doubt that we do have a major wildfire crisis on our hands," Cunningham said.
About 43% of the 200 most damaging fires occurred in the last 10 years of the study. In the 1980s, the globe averaged two of these catastrophic fires a year and a few times hit four a year. From 2014 to 2023, the world averaged nearly nine a year, including 13 in 2021. It noted that the count of these devastating infernos sharply increased in 2015, which "coincided with increasingly extreme climatic conditions." Though the study date ended in 2023, the last two years have been even more extreme, Cunningham said.
