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.

Although pieces of the analysis include degrees of uncertainty, researchers said trends show climate change increased the likelihood of the fires.

More than 200 NASA staff lost homes in the LA fires. Their tragedies bring a personal perspective to rising global climate risks.
