Ammonia from massive penguin guano deposits reacts with sulfur gases to form aerosol particles, seeding clouds over Antarctica. Measurements near a 60,000-strong Adélie colony showed ammonia levels 1,000× above baseline, triggering fog and cloud droplets that may help cool the surface.

Pinguinkot löst Wolkenbildung aus, die die Antarktis abkühlen könnte

MONGABAY

Ammoniak aus riesigen Pinguinguano-Ablagerungen reagiert mit Schwefelgasen zu Aerosolpartikeln und bildet Wolken. Messungen in der Nähe einer 60.000 Tiere umfassenden Kolonie ergaben einen 1.000-fach höheren Ammoniakspiegel als normal. Dies löst Wolkentröpfchen aus, die zur Abkühlung der Oberfläche beitragen.
