Penguins play a surprising role in shaping Antarctica’s atmosphere! A new study found that ammonia from penguin colonies, rather than the ocean, helps form new particles in the air when mixed with sulfuric acid from marine phytoplankton. Scientists used sensitive instruments to measure gases and particles on the Antarctic Peninsula, revealing how these processes contribute to cloud formation.
