New research reveals that Antarctica’s 20 million Adélie penguins are doing more than just occupying the ice—they’re actually helping to cool it. By releasing massive amounts of ammonia through their guano, these colonies trigger a chemical chain reaction that boosts cloud formation by up to 10,000 times. This "poop-powered" cloud cover acts as a natural sunshield, proving that even the smallest biological cycles play a massive role in fighting global warming.
