As wildfires continue to devastate Los Angeles, leaving thousands displaced and causing widespread destruction, experts urge long-term support and careful giving.

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.
