Global warming could reveal an ancient river landscape that has been preserved underneath the East Antarctic Ice Shelf million of years, according to a new study.

Melting in West Antarctica, a region which includes the "Doomsday Glacier," could be "unavoidable" in the future due to warming oceans, scientists say.

A passenger on an Antarctic cruise died and four others were injured after their Viking ship was struck by a "rogue wave," the cruise line said.

Images out of a northern region of Antarctica show a landscape nearly devoid of ice and snow following record-setting temperatures last week.
