Around 10,000 penguin chicks died after an ice bed they lived on broke apart, the BBC said. The emperor penguin chicks, who had not yet developed waterproof feathers, died last October.

Four out of five emperor penguin colonies in Antarctica’s Bellingshausen Sea region very likely lost their chicks late last year because of disappearing sea ice underneath their breeding grounds, according to a new study. Parts of this coastal region had lost all of their sea ice by November, which was probably before penguin chicks had grown waterproof adult feathers and learned to swim. It’s the first time scientists have seen a widespread failure across multiple penguin colonies in a region, researchers said. “At the moment, we’re not sure if this is just a blip,” said Norman Ratcliffe, a seabird ecologist with the British Antarctic Survey and one of the authors of the new study. “But if this becomes a consistent phenomena in the longer term, clearly it’s going to have repercussions for the species.”

CNN —As rapidly warming global temperatures help push Antarctica’s sea ice to unprecedented lows, it’s threatening the very existence of one of the continent’s most iconic species: emperor penguins. Emperor penguins rely on stable sea ice attached to land for nesting and raising their chicks. For the past few years, scientists have been sounding the alarm about a steep decline in Antarctica’s sea ice. In mid-July, Antarctic sea ice reached the lowest level for this time of year since records began in 1945. Antarctic sea ice also helps regulate the planet’s temperature, reflecting the sun’s incoming energy back to space.
