Ammonia from penguin poop increases cloud cover in Antarctica, reflecting sunlight and cooling the area. This natural process may help slow climate change and protect fragile ecosystems. The post ...

WASHINGTON — The population of emperor penguins in one part of Antarctica appears to be declining faster than previously thought, according to a new analysis of satellite imagery released Tuesday.

Penguin poop may help preserve Antarctic climate Ammonia aerosols from penguin guano likely play a part in the formation of heat-shielding clouds.

The colonies studied represent about 30% of the total emperor penguin population, which lives only in Antarctica. The loss of stable sea ice may be affecting the penguins in ways beyond shrinking ...

Satellite photos show emperor penguins in one region of Antarctica declined 22% in the past 15 years. That's significantly faster than prior estimates of their decline due to climate change.
