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

"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.
