Up to 150,000 Adélie penguins have ‘gone missing’ from a colony in Antarctica since a huge iceberg disrupted their access to the sea, writes Richard Collins. 

CLIMATE change effects on food sources may have contributed to a halving of penguin populations in Antarctica.

Massive icebergs and an unprecedented amount of sea ice have nearly cut off one of Antarctica’s largest populations of Adelie penguins, jeopardising attempts by the birds to breed.
