King penguins may soon be wiped out
One of the emblems of the Antarctic, the king penguin, could be driven to extinction by climate change, a French study warns. In a long-term investigation on the penguins' main breeding grounds, investigators found that a tiny warming of the Southern Ocean by the El Nino effect caused 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, they say.
