A study reveals that ammonia from Adélie penguin guano in Antarctica may help form clouds that insulate the Earth and slow down sea ice melting. Researchers found that ammonia levels surged significantly near a penguin colony, which reacts with marine phytoplankton gases to create aerosol particles that seed clouds. These clouds reflect sunlight, aiding in cooling the surface. The interconnectedness of Antarctic ecosystems and climate systems is emphasized, highlighting the urgency of understanding local processes in the context of global warming. Teljes cikk (Euronews.com)
