As California experiences one of its most severe bushfire seasons on record, the San Francisco sky turned a menacing orange on Wednesday.

“We are living in a world that has been affected by global warming, and we are feeling the impacts,”

; said Noah Diffenbaugh, professor at Stanford’s School of Earth, Energy, and Environmental Sciences, explaining the causes and context of this unusual weather event. . He told Business Insider that his research group recently found that the frequency of extreme weather conditions in California has doubled over the past 40 years.

Long-term warming, the effect of temperature on vegetation dryness and the ignition of strong winds lead to these extreme fires. The wind is also responsible for sending smoke to San Francisco. Combined smoke channels from wildfires around California blanketed the Pacific coast, blocking sunlight and causing the mysterious orange sky.

Local news channel KRON4 reported that smoke particles can scatter sunlight so that it appears red-orange when they settle in the air.

Residents posted photos and videos of the eerie horizon on social media.

Many found the sky scary, and some even compared it to the sci-fi “Blade Runner” films set in a dystopian future Los Angeles.

Several people, including Bloomberg reporter Sarah Frier, noted that they had to manually disable the color correction camera functions to capture vision.

Diffenbaugh pointed out that the fires are the result of a confluence of conditions and the warming of global temperatures is just one factor people can consider in disaster prevention. He warned that with temperatures expected to rise three to five degrees by the end of the century, there will likely be fewer resources to fight many fires simultaneously.
