A researcher at a South African base in Antarctica has been accused of physical assault and sexual harassment. South Africa said it had no immediate plans to remove the accused or any colleagues.

A massive superberg, four times as big as New York City, has halted east of the southern tip of South America.

"This is the furthest north I've heard of an emperor penguin," an expert said.

It took an icebreaker ship and two long-range helicopters to evacuate the staff member from an Australian research base to advanced medical care.

As global warming passes certain limits, dire changes will probably become irreversible, the researchers said, including the loss of polar ice sheets and the death of coral reefs.

"Gents, I want to introduce you to the Endurance." More than a century after sinking in Antarctic waters, the legendary ship was found with just days to spare.

Explorers and researchers, battling freezing temperatures, have located Endurance, Ernest Shackleton's ship that sank in the Antarctic in 1915.

A robot lowered through the ice reveals how the Thwaites shelf is melting, which will help forecast its effect on global sea level.

The collapse of the two ice shelves was most likely triggered by vast plumes of warm air from the Pacific, researchers have found.

Organizing a responsible visit to sensitive areas like the Galápagos Islands or Antarctica involves research, decoding certifications and possibly a travel adviser.

A bold engineering project might show a way to slow sea-level rise — and bring new imagination to the fight against climate change.

What if we saw Antarctica as a harbinger of transformation rather than doom?

New research indicates that a majority of emperor penguins in a region of Antarctica lost their chicks to sea ice melt.

Scientists say a period of unusual weather, combined with record-low sea ice, led to the disintegration of the Conger ice shelf.

The world today is smaller and less mysterious than when Endurance sank. At the same time, we know too much about the past to be nostalgic.

Chile's president traveled to the South Pole, the first visit of any sitting Latin American president, according to his office.

They emerged from an applicant pool of thousands to run the world's most southerly post office, monitor penguins and manage the wild landscape on Goudier Island.

It may be too late to halt the decline of the West Antarctic ice shelves, a study found, but climate action could still forestall the gravest sea level rise.

Earlier this year it was clear Antarctic sea ice levels were low. Now, as the continent enters spring, it's obvious that "it's a really exceptional year."

Next up, a yearslong ramble through the Southern Ocean and, eventually, a big melt.
