In his first remarks on the vast California wildfires … President Trump blamed the blazes on the state’s environmental policies and inaccurately claimed that water that could be used to fight the fires was “foolishly being diverted into the Pacific Ocean.” State officials and firefighting experts dismissed the president’s Twitter comments. “We have plenty of water to fight these wildfires, but let’s be clear: It’s our changing climate that is leading to more severe and destructive fires,” said Daniel Berlant, assistant deputy director of Cal Fire, the state’s fire agency. …William Stewart, a forestry specialist… said he believed Mr. Trump was referring to the battle over allocating water to irrigation versus providing river habitat for fish. …Mr. Trump raised another issue when he wrote that officials “must also tree clear to stop fire spreading.” Scientists and forest experts said the president was referring to a valid and continuing debate.
