WASHINGTON (AP) — Human-caused climate change increased the likelihood and intensity of the hot, dry and windy conditions that fanned the flames of the recent devastating Southern California wildfires, a scientific study found.

Extreme weather conditions will be more common, according to the study, adding fresh urgency to a burgeoning group of climate adaptation startups.

Climate change caused by human activity increases the risk of devastating fires, like the ones in Los Angeles, California,according to the World Weather Attribution (WWA) network. The fires left at least 29 dead and thousands homeless.
