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 .
Drier, warmer conditions lead to vegetation drying out and becoming more flammable.
President Trump made a similar threat to cut federal aid in 2018, when the most deadly fire in California’s history killed 86 people.
As of now, California is struggling with 15 active wildfires; more than thousands of acres of land has been burned down to ashes till now. It is getting extremely difficult for the authorities to contain and extinguish the wildfire at the places experiencing extreme heat.
It was only last week that wildfires reached the Big Basin Redwoods State Park, which is the oldest park in California. This old state park is home to some rare and ancient trees, some over 2000 years old.
According to climate scientists, the reason behind the California wildfires is extreme weather conditions and heat waves across the state. The maximum temperature in Death Valley reached 54 Degree Celsius and, for the first time in 20 years, the state suffered blackouts as people were trying to cool their homes which strained the electrical grid in the state.
Then came a tropical storm and lighting that instigated small fires across the Bay Area and California. Soon, humidity dropped and it turned windy, which carried flames to other places in the state and caused a lot of destruction and damage.
