Once unknown emperor penguin colonies have been spotted in Antarctica

Previously unknown colonies of emperor penguins have been spotted in new satellite imagery. Emperor penguins, considered “near threatened” with extinction, are the world’s largest penguins. They raise their chicks in Antarctic winter on patches of frozen sea ice. But if the ice breaks up before the chicks have fledged, most will die. At least some emperor penguins are moving their colonies as melting ice from climate change threatens breeding grounds, according to research released on Wednesday. One penguin colony near Halley Bay appears to have moved around 30 kilometers (19 miles) to the east, said Peter Fretwell, a researcher at the British Antarctic Survey. He said unstable conditions beginning in 2016 had made the old location perilous. “Emperor penguins have taken it...

Quark Expeditions takes explorers to Snow Hill island colony of Emperor penguins Quark Expeditions, the global leader in polar adventures, extended its longstanding record of achievement in Antarctica by successfully landing 208 explorers on two voyages for an experience that few on the planet will ever have: walking on sea ice to visit the remote Snow Hill Island colony of Emperor penguins. Quark Expeditions' technologically-advanced expedition ship, Ultramarine, and its team delivered these successful Snow Hill voyages in November and December, while also hosting a special onboard ceremony at the edge of Antarctica's Weddell Sea: the official announcement of Dr Sian Proctor as Ultramarine's godmother.

Loss of Antarctic ice killed thousands of emperor penguin

The loss of ice in one region of Antarctica last year likely resulted in none of the emperor penguin chicks surviving in four colonies, researchers reported Thursday. Emperor penguins hatch their eggs and raise their chicks on the ice that forms around the continent each Antarctic winter and melts in the summer months. Researchers used satellite imagery to look at breeding colonies in a region near Antarctica’s Bellingshausen Sea. The images showed no ice was left there in December during the Southern Hemisphere’s summer, as had occurred in 2021.

Emperor penguins now a threatened species due to climate change

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. Endangered Species Act. The U.S. Fish and Wildlife Service said emperor penguins should be protected under the law since the birds build colonies and raise their young on the Antarctic ice threatened by climate change. 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 agency's review followed a 2011 petition by the environmental group Center for Biological Diversity to list the bird under the Endangered Species Act. FILE PHOTO: Emp...

China blocks moves to step up protection of emperor penguins

China has blocked efforts to step up protection of emperor penguins that are increasingly threatened by the effects global warming is having on their natural habitat in Antarctica, officials said Friday. Dozens of countries had backed giving the world’s largest penguins special protection status at a 10-day meeting in Berlin of parties to the Antarctic Treaty. The treaty was forged in 1959 to ensure that the continent remains the preserve of science, and free of arms. FILE PHOTO: Crowds of emperor penguins on the ice in Antarctica on Dec. 21, 2005.

Emperor Penguin at serious risk of extinction due to climate change

The emperor penguin, which roams Antarctica's frozen tundra and chilly seas, is at severe risk of extinction in the next 30 to 40 years as a result of climate change, an expert from the Argentine Antarctic Institute (IAA) warned. The emperor, the world's largest penguin and one of only two penguin species endemic to Antarctica, gives birth during the Antarctic winter and requires solid sea ice from April through December to nest fledgling chicks. If the sea freezes later or melts prematurely, the emperor family cannot complete its reproductive cycle. "If the water reaches the newborn penguins, which are not ready to swim and do not have waterproof plumage, they die of the cold and drown," said biologist Marcela Libertelli, who has studied 15,000 penguins across two colonies i...
