As devastating wildfires raged across Los Angeles County this week, firefighters battling the blazes encountered fire hydrants that had no water. Why it matters: The dry fire hydrants sparked political outrage and illustrated just how unprepared municipal water systems are to combat the sorts of large-scale urban wildfires that have become more frequent with climate change.

Other fires, like the 2023 Maui fires and the 2017 Tubbs Fire in Northern California, have caused hydrants to go dry in the past, and it seems L.A. will need to go back to the drawing board if these kinds of wildfire-scale urban blazes become the new normal.

As wildfires roar into residential neighborhoods, firefighters in California and elsewhere are finding that water systems can’t keep up with the demand.
