How penguin poo is making Antarctic snow melt faster

Researchers find the birds’ guano feeds algal blooms that absorb significantly more solar energy

Penguin poo is making the Antarctic snow melt faster, a study shows. As temperatures rise, penguins are waddling closer to the south pole, with potential for this previously unrecognised phenomenon to affect a wider area.

Snow algae are tiny single-celled plants that make a home in some of the coldest places on Earth. When nutrients are scarce, the algae produces red pigments to protect itself from the sun and slow growth.
