Penguin Poop Could Limit Global Warming’s Impact on Antarctica

Large colonies of penguins in Antarctica have an ability to influence the atmosphere and could be helping reduce the impact of climate change, according to a scientific study.

Accumulated penguin excrement — or guano — emits ammonia, a gas that can contribute to the formation of clouds and which is likely generating a cooling effect by creating a buffer between the sun’s heat and Antarctica’s ice and water.
