Antarctica temperature crosses 20 degrees Celsius for first time in history.
Antarctica recorded 20.75 degrees Celsius (69,35 Fahrenheita) a week after another temperature record of 18.3 degrees Celsius was recorded in the continent.
Penguin colonies in some parts of the Antarctic have declined by more than 75% over the past half century, largely as a result of climate change, researchers say.
At the last survey in 1971, there were 122,550 pairs of penguins across all colonies on Elephant Island. But the recent count revealed just 52,786 pairs — a drop of almost 60%.
The size of the population change varied from colony to colony on Elephant Island. The biggest decline – 77% – was recorded at a colony known as Chinstrap Camp.
Climate change has led to reduced sea ice and warmer oceans, which has meant less krill, the main component of the penguins’ diet.
