Wildfires ravaged the West in 2020, especially in California, where fires burned twice the state's previous acreage record.

Upward of 8,600 fires burned more than 4 million acres in California, according to Cal Fire, as dry, windy conditions and record-breaking high temperatures fueled flames for weeks.

Across the West, more than 10 million acres burned, with Oregon and Washington experiencing particularly intense wildfires. Dozens of people died in fires in 2020, and Stanford researchers estimated 1,200 to 3,000 more people died in California from smoke inhalation-related illness.
