There are many natural phenomena around the world that puzzle scientists, especially in the absence of a scientific explanation for them, including the phenomenon of bloody ice. Local residents and researchers interested in the environment have observed that the color of the ice over some areas of the Alps has turned red, a phenomenon that spread months ago and puzzled and worried scientists. Some locals in the Swiss Alps call this phenomenon melon snow or bloody ice.
As for the scientific reason for the phenomenon, it is a large spread of a type of algae over the ice, while the search for more information is still going on. The snow algae bloomed intensively on large areas of the Alpine slopes.
Research published by the scientific journal Frontiers in Planet Science stated that the unusual spread of algae was caused by the retreat of glaciers in the region.
However, the spread of bloody ice raises concerns that the snow may absorb more heat, accelerating the rate of melting and increasing the harmful effects on the environment.
While global warming has caused the emergence of algae in elevated environments, the long-term consequences of this phenomenon will not be friendly to living organisms, according to the scientists warning, which was quoted by the magazine.
Microbiologist Heather Maughansaid, growing alpine algae act as beacons of ecosystem change that scientists are working to determine how temperature patterns are related to their prosperity. There is very little that we know. We need to go deeper.
In 2020, researchers presented a study in the journal Nature, the first estimate of the mass and distribution of snow algae colonies along the Antarctic Peninsula.
The warming of the Antarctic Peninsula has already exceeded 1.5°C of pre-industrial temperatures, and the study authors predict a net increase in snow algae volume and biomass as the peninsula warms.
