Did Global Warming Contribute to California Wildfires?

A study has revealed that climate change caused by human activities has increased the likelihood and intensity of hot, dry, and windy conditions, which have fueled wildfires in Southern California, USA.

According to the study, global warming has raised the probability of fire-prone weather conditions this month by 35% and increased their severity by 6%.

The study also highlights that other factors contributed to the rapid spread of wildfires, which destroyed thousands of homes and claimed the lives of at least 29 people.

Researchers emphasized the role of rare, strong “Santa Ana” winds, which occur only once a decade, along with a dry autumn following two years of heavy rainfall. These conditions led to the rapid growth of highly flammable grasses and shrubs, further intensified by hot weather, dry air, and vulnerable homes in fire-prone areas.

The research team analyzed the impact of climate by focusing on the Fire Weather Index, which measures atmospheric conditions that contribute to wildfire risk.

This index includes data on past rainfall, humidity levels, and wind speed. Researchers found measurable signs of climate change, demonstrating its role in intensifying wildfires.
