The wildfires ravaging Los Angeles have killed at least 10 people, displaced 180,000 and scorched about 40 square miles – an inferno driven by fierce winds and severe drought in what should be California’s wet season. It is a sobering reminder that the climate crisis is driving wildfires to become more frequent, intense and destructive – leaving ruined lives, homes and livelihoods in their wake. The US president Joe Biden responded by mobilising federal aid. By contrast the president-elect, Donald Trump, a convicted felon who was criminally sentenced on Friday, used the disaster to spread disinformation and stoke political division.
