Extreme heat and drought in the West are sparking another intense wildfire season this year, intensifying debates around President Joe Biden’s efforts to curb climate change and federal and state government forest management.

More than 1 million acres have burned already this year, which is more than the United States saw by this time in 2020, according to the National Interagency Fire Center. Arizona experienced one of its 10 largest blazes in history, and large fires have burned in Utah, California, and Alaska.
