- Penguin droppings are helping green algae grow on snow along the Antarctic Peninsula, and that green snow absorbs far more sunlight than clean white snow, a new study finds.
- Researchers found much higher levels of phosphate, a nutrient found in guano, in green snow than in red snow.
- Green snow absorbs about 40 percent more solar energy than clean snow, while red snow absorbs about 20 percent more, so the algae-tinted patches melt faster.

The scientists say current projections of Antarctic melting do not yet account for this wildlife effect, and more data is needed before it can be added to climate models.
