Study finds global increase in hot, dry days ideal for wildfires

The number of days when the weather gets hot, dry and windy – ideal to spark extreme wildfires – has nearly tripled in the past 45 years across the globe, with the trend increasing even higher in the Americas, a new study shows.
And more than half of that increase is caused by human-caused climate change, researchers calculated.
What this means is that as the world warms, more places across the globe are prone to wildfires because of increasingly synchronous fire weather, which is when multiple places have the right conditions to go up in smoke.
Countries may not have enough resources to put out all the fires, and help will not be as likely to come from neighbors busy with their own flames, according to the authors of a study in Wednesday’s Science Advances.
In 1979 and for the next 15 years, the world averaged 22 synchronous fire weather days a year for flames that stayed within large global regions, the study found. In 2023 and 2024, it was up to more than 60 days a year.
“These sorts of changes that we have seen increase the likelihood in a lot of areas that there will be fires that are going to be very challenging to suppress,” said study co-author John Abatzoglou, a fire scientist at the University of California, Merced.
