Strange “pink snow” in the Alps – a bad omen for the Earth

The amazing pink landscape of the snowy Alps is dark news for the Earth, experts say.

If the snow in the mountains takes on a reddish-pink hue, this shows algal blooms in it. While most freshwater algae begin at higher temperatures, but microorganisms in this area are able to breed at low temperatures, and these algae are red due to their carotenoid pigment.

Scientific concern about the growing presence of algae in the Alps arises from the fact that the red color increases the absorption of sunlight by snow – this means that the snow is melting even more, and the planet is heating up more and more. Biagio Di Mauro, a researcher at the Institute of Polar Sciences at the National Research Council of Italy, says that the Alps are the color of the alga Chlamydomonas nivalis, which are also found on polar caps.
