Penguin guano may help reduce effects of climate change in Antarctica
- Matthew Boyer and colleagues measured atmospheric ammonia and aerosol particle concentrations near a 60,000-strong Adélie penguin colony on the Antarctic Peninsula in early 2023.
- They conducted the study to assess how gases from penguin guano influence cloud formation over the region, as ammonia can seed cloud particles when combined with sulfuric acid.
- When winds blew from the penguin colony, ammonia concentrations spiked to 13.5 parts per billion—about a thousand times above background—causing aerosol particle levels to surge and fog formation to occur.
- Boyer highlighted that even after the penguins had departed from the colony, the ammonia released from their droppings persisted for about a month, with concentrations remaining roughly 100 times above normal levels.
- The findings suggest penguin guano may boost cloudiness and help cool Antarctica, but declining penguin populations could reduce this effect, possibly intensifying regional warming in the future.

Gaseous! Bloomberg News Hails ‘Penguin Poop’ as Savior of Antarctica from Global Warming
The B.S. doesn’t get any more odorous than this. Bloomberg News is waving around fecal matter as a method to prevent Antarctica melting from the ever-present climate boogeyman of global warming. Reporter Aaron Clark filled the toilet on Bloomberg News’s website May 22 with a story headlined, “Penguin Poop Could Limit Global Warming’s Impact on Antarctica.” Yes, this is an actual story. Clark, who based his argument on a seemingly wacky new study…
Penguin guano is an important source of climate-relevant aerosol particles in Antarctica
Gaseous ammonia, while influential in atmospheric processes, is critically underrepresented in atmospheric measurements. This limits our understanding of key climate-relevant processes, such as new particle formation, particularly in remote regions. Here, we present highly sensitive, online observations of gaseous ammonia from a coastal site in Antarctica, which allows us to constrain the mechanism of new particle formation in this region in unp…
Why penguin poop might be protecting Antarctica from rising temperatures
In December 2022, Matthew Boyer hopped on an Argentine military plane to one of the more remote habitations on Earth: Marambio Station at the tip of the Antarctic Peninsula, where the icy continent stretches toward South America. Months before that, Boyer had to ship expensive, delicate instruments that might get busted by the time he landed. “When you arrive, you have boxes that have been sometimes sitting outside in Antarctica for a month or t…
