With climate change threatening the sea ice habitat of Emperor penguins, the U.S. Fish and Wildlife Service on Tuesday announced a proposal to list the species as threatened under the Endangered Species Act.

“The lifecycle of Emperor penguins is tied to having stable sea ice, which they need to breed, to feed and to molt,” said Stephanie Jenouvrier, a penguin ecologist at the Woods Hole Oceanographic Institution.

Research published Tuesday in the journal Global Change Biology found that by 2100, 98% of Emperor penguin colonies may be pushed to the brink of extinction, if no changes are made to current rates of carbon emissions and climate change.

Around 70% of colonies will be in danger sooner, by 2050.

The new study looked at overall warming trends and the increasing likelihood of extreme weather fluctuations due to global warming. And it noted that extremely low levels of sea ice in 2016 led to a massive breeding failure of an Emperor penguin colony in Antarctica’s Halley Bay.

That year, seasonal sea ice broke up before penguin chicks had time to develop waterproof adult feathers, and about 10,000 baby birds drowned, Jenouvrier said. The colony did not recover afterward.

Emperor penguins breed exclusively in Antarctica during winter. They endure temperatures of minus 40 degrees Fahrenheit (minus 40 degrees Celsius) and wind speeds approaching 90 miles (144 kilometers) per hour by huddling together in groups of several thousand birds. But they can't survive without sufficient sea ice.

“These penguins are hard hit by the climate crisis, and the U.S. government is finally recognizing that threat,” said Sarah Uhlemann, international program director at the nonprofit Center for Biological Diversity.

The U.S. government has previously listed species outside the country as threatened, including the polar bear, which lives in Arctic regions and is also imperiled by climate change and sea ice loss.

Emperor penguins — the world's largest penguins — currently number about 270,000 to 280,000 breeding pairs, or 625,000 to 650,000 individuals. The proposed listing will be published in the Federal Register on Wednesday to open to a 60-day public comment period.

Listing the bird provides protections such as prohibition against importing them for commercial purposes. Potential impacts on penguins must also be evaluated by U.S. marine fisheries currently operating in Antarctica.

“Climate change, a priority challenge for this Administration, impacts a variety of species throughout the world," said Martha Williams, principal deputy director of the wildlife service. "The decisions made by policymakers today and during the next few decades will determine the fate of the Emperor penguin.”

Oil Price Crisis Could Lead to Speedier Push Toward Clean Energy Transition
As gas prices surge amid the Russian invasion of Ukraine, other nations could potentially transition faster to using clean energy than previously expected. Philip K. Verleger, a senior fellow at the Niskanen Center, joined Cheddar News to explain how this could be a possibility in the near future. "Part of the reason I think we have this invasion and the tantrum that's being thrown by Russia, terrible tantrum, is because the Russians were trying to slow down the transition," he said. "Ironically they speeded it up."

As Russia intensifies its war on Ukraine, President Biden announced a ban on oil imported from the aggressor nation. Critics of Russia have said this would be the best way to force Putin to pull back, but curbs on Russian oil exports are expected to send already skyrocketing oil and gas prices even higher, further impacting consumers, businesses, financial markets, and the global economy. Leslie Beyer, CEO of the Energy Workforce and Technology Council, joined Cheddar News' Closing Bell to discuss. "It's certainly going to increase pricing, but it is the right thing to do," she said. "The industry itself has already pulled out of the significant portion of its operations in Russia."

How Omicron Derailed Pfizer Vaccine for Children Under the Age of 5
Vaccine maker Pfizer delayed its COVID shot for kids allegedly due to a lack of data on how it would perform against the omnicron variant, according to the Wall Street Journa. Peter Pitts, professor and founder of the Center for Medicine in the Public Interest and a former FDA associate commissioner, joined Cheddar News Wrap to break down why the authorization can't be rushed. "Going forward, the FDA wants to look at data specifically against omicron, and it looks like that's going to be a three-shot regimen versus two, which was efficient against delta but not omicron because obviously omicron is more infectious," said Pitts.
