Emperor penguins lost thousands of chicks to melting ice last year

With continued climate warming, all emperor penguins could be at risk, scientists say

Two emperor penguin chicks stand on the ice. One has buried his head in his soft fur, while the other appears to be nodding off.

Emperor penguin chicks lack waterproof feathers, making them vulnerable to sea ice loss.

Thousands of emperor penguins in western Antarctica lost their chicks last year, largely due to receding sea ice, satellite data suggest.
