Why snow is turning pink at high altitudes
AYESHA RASCOE, HOST:
You've heard of white snow, maybe even gray snow, but what about pink snow? High up in the mountains across the U.S., rapid growth of algae, or algal blooms, are turning melting snow pink. They further darken the surface of the snow and make it melt more quickly, and scientists are trying to understand what's causing them and how they impact water levels in drought-prone areas. One of those scientists is Robin Kodner, an associate professor of environmental science at Western Washington University. And she's here to talk with us today. Welcome to the show.
ROBIN KODNER: Thank you.
