Brown spots reveal Antarctic penguin problem
In order to survive the cold, emperor penguins must remain on platforms of sea ice for long enough every year to replace weather-beaten feathers with new waterproof coats.
Little was known about what is called catastrophic moulting until researchers at the British Antarctic Survey looked at satellite pictures of the frozen continent and spotted brown smudges. They realised they were mounds of feathers. But global warming is now rapidly changing Antarctica.
Satellite images show that after summer sea ice shrank dramatically in 2022 and 23, there were fewer smudges, suggesting many penguins had died in West Antarctica.
There is hope that some move to safer ice, but it is another sign of how climate change is endangering some of the world's most vulnerable animals.
