While red and pink are the most common colors, different types of snow algae produce a rainbow of hues, including orange, yellow and green.

However, the red bloom isn't triggered only by access to nutrients and melting snow waters, it's also connected to temperature increases. The red pigment acts as a sunscreen of sorts for the ...

A strange pink algae that grows on snow and ice is melting glaciers, making them more prone to soak up the heat from the sun.

There's more available habitat for these snow algae blooms to occur," said Hotaling when asked about the frequency of these blooms this year.

They lose their reflectiveness when airborne dust settles onto their surface, or when dark-red blooms of snow algae grow and absorb solar energy.

A massive algae bloom has stained the glacier in Siberia, prompting a warning from Russian scientists.

Pink, red, purple, and green algae blooms are growing on glaciers all over the planet. Scientists who study snow and ice algae fear the blooms are a symptom of climate change. Algae blooms can ...

NPR's Ayesha Rascoe asks Western Washington University environmental science professor Robin Kodner about algea that is turning snow pink at high altitudes.

That bloom is a sign of the algae’s reproductive stage, during which there’s a secondary pigment that’s created which darkens the algae’s cells, according to Hotaling.

Researchers may finally be able to forecast dangerous red algae blooms Red tides can lead to millions of dollars in losses, kill animals and be harmful to human health ...
