Oregon’s Bootleg Fire, now the largest fire in the nation, is inching closer to a Californian forest critical to its climate-centric cap and trade program.

The 212,000-acre fire is burning in Fremont-Winema National Forest, placing 100 homes in Klamath County under evacuation orders since it was first reported on July 6. Since then, the Bootleg Fire has doubled in size every 48 hours. From July 9 to July 14, the fire has doubled in size almost daily.
