Uncontrolled blazes across the state this year have so far burned a historic 2.3 million acres, representing a nearly 2,000% increase in land burned compared with this time last year, according to the California Department of Forestry and Fire Protection.⁠⠀ ⁠⠀ “This is yet another reminder though that we’re living with the effects of climate change in real time,” San Francisco Mayor London Breed tweeted Wednesday morning. ⁠⠀ ⁠⠀ Here are some images of Wednesday’s orange skies, which many compared to a scene from Mars. // 📷 The San Francisco Chronicle via Getty Images」9月11日 0時24分
