Watermelon Snow: Not Edible but Important for Climate Change

In snowy places across the globe, watermelon snow forms as the summer sun heats up and melts winters leftovers. The colorful snow is made up of communities of algae that thrive in freezing temperatures and liquid water, resulting in algal blooms. When these typically green organisms get a lot of sun, they produce a natural type of sunscreen that paints the slopes pink and red. The addition of color to the surface darkens the snow, allowing it to heat up faster, and melt more quickly.

.

Imagine wearing black instead of a white T-shirt in the sun. It feels much hotter, wrote Stefanie Lutz, a geobiologist at GFZ German Research Center for Geosciences, in an email. It is the same for the snow: More heat means more melting.

.

Dr. Lutz, together with Liane Benning and their colleagues at a number of universities, published a study Thursday in Nature Communications that examined microbes in summer snow, and noted that while bacterial communities differ from place to place, the same algae that produce watermelon snow appear to be so global that its time for climate models to consider their effects on snow and ice melt.

.

Algae changes snows albedo, or how much light, or radiation, its surface reflects back into the atmosphere. Based on 40 samples from four locations, the new study estimated that blooms of snow algae can lead to an albedo decrease of 13 percent over the course of an Arctic melt season, compared with clean snow, meaning the dark snow would absorb much more light. Just how much melting this will account for, or how much that may affect sea level rise, however, is still to be determined. But algal effects on albedo are going to be important for melting glaciers, which play a huge role in the climate system, said Dr. Lutz.
