Before one of the most destructive fires in California history swept through, the Pacific Palisades neighborhood on Los Angeles' west side was filled with expensive homes fronted by green, well-tended landscaping and popular boutiques and cafes.

"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.

Economic losses and damage are an estimated $135 billion and $150 billion, the costliest fire event in US history. Hurricane Helene in six states last fall caused up to $250 billion in damage.
