150 Million Years Old Turtle Fossil Discovered

A turtle fossil dating back 150 million years to the Jurassic Period has been found in southwest China`s Chongqing municipality.

Paleontologists from the municipal exploration bureau confirmed it was a fossil of a snake-necked turtle from the Jurassic Period.

Jurassic turtle fossils were previously found in Chongqing and in the neighbouring Sichuan province, but it is the first time that a snake-necked turtle fossil was found in the area.

Rising Bedrock Could Slow Antarctic Ice Sheet Melting

An international team of researchers has found that the bedrock below the remote West Antarctic Ice Sheet is rising much more rapidly than previously thought, in response to ongoing ice melt.

The study, "Observed rapid bedrock uplift in the Amundsen Sea Embayment promotes ice-sheet stability," reveals new insights on the geology of the region and its interaction with the ice sheet. The authors noted that the findings have important implications in understanding and predicting the stability of the ice sheet and Earth's rising sea levels.

High-altitude Rubbish Dump

Decades of commercial mountaineering have turned Mount Everest into the world's highest rubbish dump as an increasing number of climbers pay little attention to the ugly footprint they leave behind.

Fluorescent tents, discarded climbing equipment, empty gas canisters and even human excrement litter the route to the summit of the 8,848-metre (29,029-foot) peak.

Melting glaciers caused by global warming are exposing trash that has accumulated on the mountain since Edmund Hillary and Tenzing Norgay made the first successful summit 65 years ago.

Antarctic Ice Melting Faster Than Ever

Satellites monitoring the state of the White Continent indicate some 200 billion tonnes a year are now being lost to the ocean as a result of melting.

This is pushing up global sea levels by 0.6mm annually - a three-fold increase since 2012 when the last such assessment was undertaken.

According to researchers, the losses are occurring predominantly in the West of the continent, where warm waters are getting under and melting the fronts of glaciers that terminate in the ocean.

Oldest Footprints Found in China

The oldest known footprints left by an animal have been uncovered in southern China.

The identity of the creature that made the 546-million-year-old tracks is still unknown, but they come from the period when the earliest animals are thought to have evolved.

It is unclear whether the creature had two legs or several. But they say the tracks probably belong to a bilaterian.
