The team used observations of past weather and computer simulations that compared what happened this month to a what-if world without the 1.3 degrees Celsius (2.3 degrees Celsius) of human-caused climate change.

Human-caused climate change made the Los Angeles-area fires more likely and more destructive, according to a study out Tuesday. Why it matters: The study — from an international group of 32 climate researchers — shows how climate change fits into the myriad factors that made the multiple blazes one of California's most destructive and expensive wildfire disasters on record.

The recent wildfires in California were worsened by climate change, a new report found. The study, released Tuesday by the World Weather Attribution, found that human-caused climate change increased the chances of hot,
