Wildfires in Southern California have burned tens of thousands of acres, destroyed thousands of buildings, and killed at least 10 people. Experts say global warming may have set the stage for the catastrophic blazes.

Collectively, the losses — whether in the hundreds or, as is far more likely, in the thousands — will weigh on the city’s already urgent housing shortage.

Firefighters say that the fire is moving with a "rapid rate of spread," prompting evacuation orders for 3,000 Sylmar residents.
