New research reveals that penguin guano in Antarctica supplies significant ammonia aerosols, influencing cloud formation that cools the planet by reflecting sunlight. The ammonia particles interact with ocean algae, triggering a chemical reaction forming numerous particles that act as nuclei for water droplets. These low clouds are critical to the climate system, yet their response to human-induced warming is uncertain. A recent study links reduced cloud cover to increased global temperatures, emphasizing the interconnectedness of ecosystem processes and climate dynamics.
I'm constantly surprised at the depth of how one small change affects everything else. This really does show that there is a deep connection between ecosystem processes and the climate.
New research shows that penguin guano in Antarctica is an important source of ammonia aerosol particles that help drive the formation and persistence of low clouds.
