A new global analysis finds that the rising number of extreme fire weather days since 1980 carries a clear human-caused climate signal.

Increasing extreme fire weather conditions may raise wildfire risk in many regions.

Extreme fire weather—conditions that are hot, dry, and windy enough to spread wildfires rapidly—has intensified worldwide over the past four decades. A new global analysis published in Science Advances finds that this increase now carries a detectable signal from human-driven climate change.

Researchers examined changes in the frequency of extreme fire weather days between 1980 and 2023 using observational records and climate model simulations. Their analysis shows that the upward trend cannot be explained solely by natural climate variability.

Detecting a Climate Signal in Fire Weather

Wildfires depend on several interacting factors, including ignition sources, fuel availability, and weather conditions. Among these influences, fire weather—defined by combinations of high temperatures, low humidity, and strong winds—plays a major role in determining how quickly fires ignite and spread.

Satellite observations show how wildfire activity responds to changing weather and climate conditions.

To measure these conditions, the study analyzed the Fire
