One of the biggest icebergs on record has broken away from Antarctica. With its one trillion tonnes of ice it calved away from the Larsen C Ice Shelf. Throughout the Antarctic winter, scientists monitored the progress of the rift.
With the king penguin's food supply being driven farther and farther away, the birds must choose between feeding and breeding. The penguin's plight sends a warning about the future of the Antarctic's environment.
Where a trillion-ton iceberg calved last week, researchers have detected a new rift. The concern is that the Larsen C ice shelf will destabilize and collapse, releasing glacial ice into the sea.
So far, the Antarctic was seen as relatively stable. But a new study suggests that climate change is affecting the polar region on a much larger scale than previously believed – which could have devastating consequences.
A piece of ice the size of the US state of Delaware is close to breaking off from one of Antarctica's largest ice shelves. The break could destabilize the Larsen C ice shelf.
