Cosmopolitan snow algae accelerate the melting of Arctic glaciers

The role of red pigmented snow algae in melting Arctic glaciers has been strongly underestimated, suggests a study to be published in NATURE Communications on June 22. White areas covered with snow and ice reflect sunlight; the effect is called albedo. It has been known for quite some time that red pigmented snow algae blooming on icy surfaces darken the surface which in turn leads to less albedo and a higher uptake of heat… Source
