- Summary- Antarctica’s emperor penguins are threatened by sea ice loss- Warming temperatures have already caused mass breeding failuresOct 25 New York (Reuters) - Antarctica’s emperor penguin is at risk of extinction due to rising global temperatures and sea ice loss, the U.S. government said Tuesday as it finalized protections for the animal under the U.S.The wildlife agency said a thorough review of evidence, including satellite data from 40 years showed the penguins aren’t currently in danger of extinction, but rising temperatures signal that is likely.The Halley Bay colony in the Weddell Sea, the second-largest emperor penguin colony in the world, experienced several years of poor sea ice conditions, leading to the drowning of all newborn chicks beginning in 2016, the government said.“The penguin’s very existence depends on whether our government takes strong action now to cut climate-heating fossil fuels and prevent irreversible damage to life on Earth,” Wolf said.The 1973 Endangered Species Act is credited with bringing several animals back from the brink of extinction, including grizzly bears, bald eagles, gray whales and others."
