Emperor Penguins Now Listed as Endangered

For over 60 years, the International Union for Conservation of Nature (IUCN) has assessed and reported the risk status of animals around the globe, from Least Concern to Extinct.  On April 9, 2026, the IUCN announced the elevation of Emperor penguins to Endangered status, a two step jump from their previous listing of Near threatened.  

A Hot Topic

Climate change is the primary culprit for the decrease in numbers.  Emperor penguins do not build nests; rather, they lay their eggs and raise their chicks on “fast ice” (frozen seawater that is attached to the coasts).  When temperatures increase, the ice melts prematurely, and vulnerable chicks may be forced into the ocean before they’re ready.  If their vital waterproof feathers haven’t grown in yet, the chicks will freeze or drown.

The Sobering Facts

“Satellite images indicate a loss of around 10% of the population between 2009 and 2018 alone,” the IUCN press release reports.  If nothing changes, the Emperor penguin population could be cut in half in the next 50 years.

An Eye on Antarctica

Emperor penguins are considered a sentinel species.  They are one of the only penguin species (along with Adelie penguins) to live and breed exclusively on the Antarctic continent.  Measuring their decline acts as an early warning system to inform scientists of the health of Antarctica and the state of climate change in the world.  The status shift of Emperor penguins is an alarm bell ringing, one that if unheeded could have disastrous consequences for everyone.  The World Wildlife Federation is now calling for Emperor penguins to be designated as a Specially Protected Species.
