Geologists exploring the vast West Antarctic ice sheet have discovered the remains of an ancient river system that once stretched nearly 1,000 miles (1,600 kilometers). The discovery offers a glimpse into Earth’s history and hints at how extreme climate change could reshape the planet, according to their findings published June 5 in the journal Science … Read more
Millions of years ago, Antarctica looked very different from the icy landscape we know today. A research expedition led by the Alfred Wegener Institute has uncovered a hidden secret. Geologists discovered evidence of an ancient river system by studying sediment samples from the Amundsen Sea. This suggests that Antarctica supported a temperate climate about 34 … Read more
Geologists digging into West Antarctica’s vast ice sheet have discovered the remains of an ancient river system that once flowed nearly a thousand miles. The discovery offers a glimpse into Earth’s history and indicates how extreme climate change could change the planet, according to their findings, published June 5 in the journal Science Advances. “When … Read more

Scientists have discovered that a river comparable in size to the Rio Grande once dominated West Antarctica, offering a rare glimpse of the continent’s land covered in ice today. It is believed that the 900-mile-long waterway flowed about 44 to 34 million years ago, shortly before the continent’s immensely thick ice sheets began to build … Read more
