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.

Climate change was a major factor behind the hot, dry weather that gave rise to the devastating LA fires, a scientific study has confirmed. It made those weather conditions about 35% more likely, according to World Weather Attribution - globally recognised for their studies linking extreme weather to climate change.
