Red skies over San Francisco: American city covered with haze after wildfires

Smoke from wildfires in California covered San Francisco, causing the sky over the city to turn red-orange. This effect arose due to the accumulation of smoke in the atmosphere - it stopped transmitting waves of blue light, allowing only the colors of the warm part of the spectrum to penetrate to the ground.
