US EditionExtreme Fire Weather Days Have Nearly Tripled Globally Since 1979: Study
A study shows human-driven climate change caused over 60% of the rise in simultaneous extreme fire weather days globally, increasing strain on firefighting resources.
- Researchers at the University of California, Merced show that the number of synchronous fire-weather days has nearly tripled worldwide over 45 years, with recent figures exceeding 60 days, according to a study. Yin said, `And that's where things begin to break`.
- Researchers said more than 60% of the global increase is attributed to climate change from burning coal, oil and natural gas, based on simulations comparing observed conditions with a fictional world, Yin said.
- Only one region bucked the trend: the region, which jumped from 5.5 to 70.6 days, including 118 days in 2023, Yin noted.
- Mutual‑aid systems could be strained, meaning researchers warned that countries may lack resources to fight simultaneous fires, and authors said these fires will be very challenging to suppress.
- Methodologically, the team focused on weather conditions—not actual fires—and Flannigan noted oxygen, fuel and ignition also affect outbreaks, with Abatzoglou saying, `And that's where things begin to break`.

The number of annual days with a high risk of forest fire worldwide has almost tripled in recent decades.
According to a recent study, the risk of forest fires has increased dramatically, so the progressive global warming also makes simultaneous fires more likely in different regions.
The number of days with hot, dry and windy weather, ideal for the outbreak of extreme wildfires, has nearly tripled in the last 45 years worldwide, with an even greater trend in the United States, a new study shows.
A study finds warming world increases days when weather is prone to fires around the globe
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.
Skyrocket in Synchronous Fire Weather: Global Wildfire Threat Grows | Science-Environment
Skyrocket in Synchronous Fire Weather: Global Wildfire Threat Grows Research reveals a rapid increase in globally synchronous fire weather events, with numbers tripling over the past 45 years. This intensifying pattern, transparent in the Americas, largely stems from climate change, according to a new analysis.The study, led by John Abatzoglou and Cong Yin from the University of California, focuses on weather conditions that lead to wildfires bu…
