In early 2019, black snow fell from the sky in several towns in the Siberian region of Kuzbass. About 2.6 million people live in the area. Most locals work in the area’s coal fields, which are the world’s largest.
Scientists say the snow is tainted with black coal dust that has been released from the area’s coal pits – and this isn’t the first time black snow has fallen from the sky. In fact, it’s a common occurrence in the area. One resident told reporters:
“It’s harder to find white snow than black snow during the winter. There is a lot of coal dust in the air all the time. When snow falls, it just becomes visible. You can’t see it the rest of the year, but it is still there.”
