Emperor penguins must surely have one of the toughest existences. After watching the new David Attenborough DVD Dynasties I was again reminded of just how tough it is to survive for some animals. New research has found that there has been a 'catastrophic' failure of these amazingly resilient animals to raise chicks for three years in a row, that no chicks had survived. These penguins need the sea ice to breed and without it the new generations of Emperors won't exist. For the creatures relying on the cold and ice to survive it's a bleak future at the rate that it's all melting.
