Scientists have made a surprising discovery: penguin droppings in Antarctica may contribute to cooling the continent. Ammonia released from penguin guano combines with compounds from phytoplankton, boosting the formation of cloud-seeding aerosols. These aerosols then create low-lying clouds that reflect sunlight, potentially offsetting some warming effects, highlighting the intricate link between ecosystems and climate.
