According to US reports, Canadian authorities evacuated the city of Yellowknife, the largest city in the far north of the country, against the backdrop of forest fires, while the sky of the region was painted red amid air pollution with thick smoke and fire emissions.
Scientifically, the sky can appear red or orange when there is wildfire smoke due to the spread of sunlight or “wavelengths” in the atmosphere, and sunlight contains all the colors of the rainbow.

When sunlight passes through Earth’s atmosphere, the particles in the air reflect specific “wavelengths,” and during a clear day, shorter “wavelengths,” such as green, blue, and violet, are not reflected, making the sky appear blue during the day.
More than a thousand wildfires are currently active in Canada, including about 230 in the northwest, highlighting the extreme heat in the northern hemisphere.
Massive wildfires in Canada during the summer
