Antarctica's icy wilderness is warming rapidly under the weight of human-driven climate change, yet a new study points to an unlikely ally in the fight to keep the continent cool: penguin poo.
Published Thursday in Communications Earth & Environment, the research shows that ammonia wafting off penguin guano seeds extra cloud cover above coastal Antarctica, likely blocking sunlight and nudging temperatures down.
