Though many Los Angeles-area parks and museums closed because of air quality or other concerns, several have reopened, including Griffith Park, the L.A. Zoo and Autry Museum of the American West.

Extreme conditions helped drive the fast-moving fires that destroyed thousands of homes in the Pacific Palisades and Altadena.

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.
