As unprecedented wildfires raged through Los Angeles, some firefighters suddenly lost access to water. City officials called one shortage a “worst-case scenario”—one they expect to see again in the future.

Los Angeles officials said a "tremendous" demand — four times normal levels — during the Palisades fire caused some hydrants to run dry.

Water experts dismissed Trump’s claims that California water policy is to blame for dry hydrants. But Los Angeles is also unprepared for the age of urban wildfires.

Though wildfires have always happened, warming global temperatures are making them more frequent and severe. For instance, scientists calculated last year that our overheating planet has contributed to a 172% increase in areas burned by wildfires in California since the 1970s.

Some Los Angeles fire hydrants ran dry in recent days as demand soared for water to quell fast-moving wildfires.
