As California experiences one of its most severe wildfire seasons on record, the sky in San Francisco turned an ominous orange colour on Wednesday.
“We are living in a world that has been influenced by global warming, and we’re feeling the impacts,” Noah Diffenbaugh, a professor at Stanford’s School of Earth, Energy, and Environmental Sciences, said, 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 wildfire weather in California has doubled over the last 40 years.

Long term warming, the temperature’s effect on the dryness of vegetation, and the ignition of strong winds lead to these extreme fires. The wind is also responsible for sending smoke towards San Francisco. The combined smoke flumes from fires around California have blanketed the Pacific coast, blocking sunlight and causing the eerie orange sky.

Local news channel KRON4 reported that smoke particles can scatter sunlight in a way that it appears reddish-orange as they settle in the air.
Residents posted photos and videos of the unsettling horizon on social media.

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

Several people, including Bloomberg reporter Sarah Frier, noted that they had to manually turn off colour-correcting camera features to capture the view.

Diffenbaugh emphasised that that wildfires result from a confluence of conditions, and warming global temperatures are just one factor that people can consider in disaster prevention. He warned that with temperatures projected to increase three to five degrees by the end of the century, there will likely be fewer resources to fight many fires burning simultaneously.
People across the Bay Area have woken to a surreal scene: smoke from wildland fires across the state have blown in, painting the sky shades of orange. Salesforce Tower is barely visible and the Coca-Cola sign still shines bright as the sun tries to pierce through.#SanFrancisco pic.twitter.com/mHzdkszxLX
