The [“State of Antarctic Penguins”](https://oceanites.org/wp-content/uploads/2017/04/Oceanites-SOAP-Report-4-25-17.pdf "undefined") report by Ron Naveen, completed over two decades, revealed that two of the most common penguin species, the Adélies and chinstraps, are in decline due largely to climate change. The report was released on Tuesday, which is also World Penguin Day. “In one generation, I have personally witnessed the precipitous decline of once abundant Adélie and chinstrap penguin populations,” Naveen told [_USA Today_.](https://www.usatoday.com/story/tech/sciencefair/2017/04/25/brrrd-count-penguin-population-antarctica-12-million-report-says/100839574/ "undefined") “These iconic birds are literally canaries in the coal mine.” He added that reduction in [Antarctic](http://time.com/4592866/greenland-ice-sea-level-rise-climate-change/ "undefined") penguins is “affirmation” that the climate is “changing in a real radical way.” The study does report, however, that the gentoo species has seen an increase in population and that, while the general population has declined, Adélie penguins have seen population growth in certain parts of the Antarctic. Naveen told _USA Today_ that monitoring penguin population is “one of the best way to track the impact of climate change and ocean health in the world’s most pristine scientific laboratory.” “Looking ahead, a number of developments deserve attention, which we’ll follow in future ‘State Of Antarctic Penguins’ reports,” the study reads. “Ultimately, all relate to climate.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4754297/penguin-population-antarctica/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4754297/penguin-population-antarctica/"},"headline":"With 12 Million Penguins in Antarctica, Population Size Still a Concern","datePublished":"2017-04-25T16:38:13.000Z","dateModified":"2026-02-23T04:35:38.828Z","description":"The report was released on Tuesday, which is also World Penguin Day","url":"https://time.com/4754297/penguin-population-antarctica/","keywords":["animals","onetime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt57f302af0d99e556/6988ca83bc6cfc00d93e10b2/gettyimages-672178392.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Lisa Marie Segarra","jobTitle":null,"url":"https://time.com/author/lisa-marie-segarra/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt57f302af0d99e556/6988ca83bc6cfc00d93e10b2/gettyimages-672178392.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"penguin-population-size","caption":"Gentoo penguins at Istanbul Aquarium","creditText":"Photograph by Veli Gurgah—Getty/Anadolu Agency","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/animals/","name":"animals"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4754297/penguin-population-antarctica/","name":"With 12 Million Penguins in Antarctica, Population Size Still a Concern"}}]}] ```
