Thousands of emperor penguins killed in the Antarctic BBC News

Reduction in sea ice in Antarctica has resulted in the deaths of an estimated 10,000 emperor penguin chicks.

In 2022, satellites recorded a colony of emperor penguins disappearing into the Bellingshausen Sea as the ice they were living on melted away.

The chicks had not fully developed waterproof feathers and they most likely froze to death.

Emperors rely on sea-ice to breed and as the world warms due to climate change - they are increasingly vulnerable.
