As ESA’s Envisat satellite marks ten years in orbit, it continues to observe the rapid retreat of one of Antarctica’s ice shelves due to climate warming.

As temperatures warm along Antarctica’s outer fringes, it allows for invasive plants and organisms to be carried in inadvertently by visiting scientists and tourists, putting the pristine ecosystem at risk, researchers have found.

An international team of researchers has combined data from multiple sources to provide the clearest account yet of how much glacial ice surges into the sea following the collapse of Antarctic ice shelves.

Analysis of direct climate record shows Antarctic tundra persisted until 12 million years ago.

Scientists have observed a "super-aggregation" of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula.
