Trump and Biden clash over U.S. wildfires as campaign turns to climate change

Joe Biden branded President Donald Trump a “climate arsonist” on Monday for refusing to acknowledge global warming’s role in deadly wildfires sweeping the western United States, while Trump blamed lax forestry and declared, “I don’t think science knows.”

Dozens of conflagrations have raged with unprecedented scope across some 4.5 million acres (1.8 million hectares) in Oregon, California and Washington state since August, laying waste to several small towns, destroying thousands of homes and killing at least 36 people.
