Story summary

Penguin guano in Antarctica plays a surprising role in shaping local climate and cloud formation. Ammonia from their droppings interacts with oceanic sulfur, amplifying aerosol particle creation by an astonishing 10,000 times. This phenomenon could cool the region by reflecting sunlight, but its full impact on climate remains a mystery, highlighting the need for deeper understanding in climate models.
