Antarctica's king penguins could be driven to extinction by climate change
King penuins' diet of small fish and squid depend on krill, which are sensitive to small rises in sea temperature
an international team of investigators looked at the penguins' main breeding grounds they found that a tiny warming of the Southern Ocean by the El NiƱo led to a massive fall in the birds' ability to survive.
If predictions by
UN scientists of ever-higher temperatures in coming decades prove true, the species faces a major risk of being wiped out
King penguins (Aptenodytes patagonicus) are second in size only to the emperor penguin and live on islands on the fringes of Antarctica
The species is unusual in that it takes a whole year for all the birds to complete their breeding cycle
the birds are vulnerable to downturns in seasonal food resources
