Human-driven climate change made wildfires in parts of South America and Southern California many times larger and more destructive, according to an annual assessment by international experts.

According to climate models, the Los Angeles wildfires in January were twice as likely and 25 times larger, in terms of burned area, in the current climate than they would have been in a world with no human-caused global warming.
