Penguin poop dramatically alters Antarctic climate, say researchers, accelerating particle formation and possibly influencing cloud creation.The study reveals that ammonia from penguin guano acts as a powerful catalyst, boosting dimethyl sulfide‘s role in the process. This is especially consequential given the lack of other particle sources in the region. Changes to this ammonia source could significantly shift the climate effect over time. Considering the far-reaching impact, even after the penguins depart, and the relationship to warming and cooling, understanding this interplay is key.

Penguin guano’s Impact on Antarctic Climate
Updated may 25, 2025
Penguin guano in Antarctica plays a significant role in particle formation, perhaps affecting cloud creation and regional climate, according to new research. The ammonia from the guano supercharges the process of particle formation, said researcher Boyer.
The key component is dimethyl sulfide from phytoplankton, wich emits sulfur.Boyer said that ammonia enhances the rate of particle formation. He added that sulfuric acid can form new particles without ammonia,but the presence of ammonia accelerates the process dramatically—up to four orders of magnitude faster.
This process is particularly important in Antarctica because there are few alternative particle sources, such as pollution or tree emissions. The strength of the ammonia source influences its climate effect over time,Boyer noted,adding that changes to the source will alter the climate effect.
Further research is needed to determine whether penguin guano has a net cooling effect on the climate. However, Boyer said that if the particles are transported out to sea and contribute to cloud formation, they generally have a cooling effect.
“It’s really the dimethyl sulfide from phytoplankton that gives off the sulfur,” he said. “The ammonia enhances the formation rate of particles…we’re talking up to four orders of magnitude faster as of the guano.”
Boyer also noted that clouds over ice surfaces could lead to warming because clouds are less reflective than ice. In this scenario, clouds could reduce the amount of heat reflected away from the planet. The study did not measure this effect, but Boyer suggested it could be an important area for future research.
The effects of penguin guano linger even after the birds leave their breeding areas. A month after their departure, ammonia levels in the air remained 1,000 times higher than baseline levels.
Ammonia emission is temperature-dependent, so Boyer believes that the ammonia likely freezes during winter. He hypothesizes that as temperatures rise, the guano will emit ammonia again, even before the penguins return. As penguins move along the coast, they might potentially be fertilizing the entire coastline with ammonia, affecting Antarctic climate.
What’s next
Future studies could examine the long-term impact of penguin guano on cloud formation and regional temperatures, providing a clearer understanding of its role in the Antarctic climate system.
