A sudden salinity spike in the Southern Ocean is accelerating Antarctic ice loss and triggering a dangerous climate feedback ...

A new study of Antarctic seals shows that environmental conditions are leading to a severe decline in their populations in the South Orkney Islands. New results are published today (Wednesday 18 June) ...

Populations of Antarctic seals have halved over 50 years amid a warming climate and shrinking sea ice, a new study has shown.

A new study shows that melting sea ice due to increasing temperatures is leading to a "concerning" and severe decline in ...

In recent years, the Southern Ocean has undergone one of the most dramatic environmental shifts observed anywhere on Earth.

It found that Weddell seals, which depend heavily on sea ice to breed and feed, and Antarctic fur seals, which breed on land but are still affected by environmental impacts on the food chain, have ...

Antarctic sea ice extent has fallen dramatically in recent years – the effects include accelerated ocean warming, faster loss ...

A harp seal pup sits on a snow-covered beach near the town of Blanc-Sablon, Québec, in early March. Normally harp seals give birth and raise their pups on sea ice in the Gulf of St. Lawrence, but ...

The colonies studied represent about 30% of the total emperor penguin population, which lives only in Antarctica. The loss of stable sea ice may be affecting the penguins in ways beyond shrinking ...

Warming is thinning and destabilizing the ice under the penguins' feet in their breeding grounds. Emperor penguin (Aptenodytes forsteri) pair on sea ice, Larsen B Ice Shelf, Weddell Sea, Antarctica.
