The East Troublesome Fire has exploded across Colorado’s Grand County, growing by about 100,000 acres Wednesday night and another 50,000 acres yesterday. The blaze — raging during a severe drought at an elevation that usually sees snow at this time of year, fueled by high winds and record heat, and engulfing timber killed or weakened by a bark beetle infestation — bears nearly all the hallmarks of climate change. The East Troublesome fire has burned more than 170,000 acres, making it the second-largest in Colorado history, though it could merge with the Cameron Peak Fire, the state’s largest ever fire. “I can’t begin to tell you, it was so gut-wrenching when I opened up the [home security camera] app and I saw fire coming up our driveway and up the hillside,” Katy Brown told CNN affiliate KUSA. “It was horrific, absolutely horrific to watch. I’ve never experienced anything like that before.” (Washington Post $, CNN, NPR, New York Times $, AP, Bloomberg $, Colorado Public Radio, CBS4-Denver; Climate Signals background: Wildfires, 2020 Western wildfire season)
