The Arctic region is warming much faster than the rest of the planet. The rapid loss of ice affects the polar jet stream, which influences weather patterns across the northern hemisphere.
The big wildcard for sea level rise is Antarctica.

If emissions continue at their current pace, Antarctica will cross a threshold into runaway sea rise when today’s kids are raising families. Pulling CO2 out of the air later won’t stop the ice loss.
Antarctic research has historically been a bastion of men from Europe and North America. Only now is the field opening up to women and people of colour. And there’s a way to go yet.

Microphones on the seafloor recorded life under the Antarctic ice for two years – inadvertently catching seal trills and chirps that are above the range of human hearing. Could they be for navigation?
‘Antarctic cities’ residents care deeply about the continent, with environmental concerns outweighing economic priorities. Asked about its future, they feel a mix of hope, pessimism and sadness.

Paleontologists have discovered fossil remains belonging to an enormous ‘toothed’ bird that lived for a period of about 60 million years after dinosaurs.
As the world warmed from the last ice age, a rise in carbon dioxide levels stalled for nearly 2,000 years. That’s always puzzled scientists, but now they think they know what happened.
Latest research explores how a warming ocean circulates underneath Antarctica’s floating ice shelves and how this contributes to future sea level rise.

Over the past 30 years, the South Pole has been one of the fastest changing places on Earth, warming more than three times quicker than the rest of the world.

Climate models have been overestimating how much sunlight hits the Southern Ocean. This is because the clouds there are different from clouds anywhere else. Bacterial DNA helped us understand why.
