For five consecutive days, wildfires fanned by strong winds have ravaged neighborhoods in Los Angeles, destroying more than 12,300 homes and buildings and leaving at least 11 dead. Fresh evacuations were ordered from Mandeville Canyon to the Interstate 405 freeway on Friday evening because of a flare up of the massive Palisades Fire.

"Climate change, including increased heat, extended drought, and a thirsty atmosphere, has been a key driver in increasing the risk and extent of wildfires in the western United States," the National Oceanic and Atmospheric Administration says.

The largest of the wildfires ravaging the area shifted direction, triggering more evacuation orders and posing a new challenge to exhausted firefighters.
