Although pink snow may seem “aesthetically pleasing,” it is not necessarily an environmental plus. The rosy hues are not indicative of optimism, but rather of tough times ahead for humans and polar bears.
This “blood or watermelon snow” (caused by growth of the red algae Chlamydomonas nivalis) melts more quickly than white varieties. Red retains more heat than white does. Pretty pink snow may therefore intensify global-warming effects.
