US President Donald Trump has threatened to cut federal funding for the wildfires sweeping California, in a Twitter spat with the state’s governor.
Nearly 100,000 acres have been destroyed by wildfires in recent weeks, and thousands have been forced from their homes.
Mr. Trump blamed Governor Gavin Newsom, a Democrat, saying he had done a “terrible job of forest management”.
Several of this year’s major wildfires have burned in unforested areas.
“Every year, as the fire’s (sic) rage & California burns, it is the same thing – and then he comes to the Federal Government for $$$ help. No more. Get your act together Governor,” Mr Trump wrote on Twitter.
Mr. Newsom, who has been highly critical of Mr Trump’s environmental policies, responded: “You don’t believe in climate change. You are excused from this conversation.”
Increased temperatures due to global warming are causing huge wildfires in California, according to a recent study published in the Proceedings of the National Academy of Sciences.
