Why is alpine snow turning red?
The peculiar phenomenon – sometimes known as blood snow – is the result of a defence mechanism produced by microscopic algae that grow in the Alpine snow. Normally these microalgae have a green colour as they contain chlorophyll, the family of pigments produced by most plants to help them absorb energy from sunlight.

Feedback Loop
The red color causes less sunlight to be reflected off the snow, causing it to melt faster, as the Ukrainian team explains in its post. The accelerated melting then causes more algae to grow, completing the cycle.

What is the yellow snow?
