Sudden ice loss in Antarctica affecting Earth’s gravitational field

In a recent research, a team of scientists have published that Antarctica is experiencing a sudden increase in ice loss which is causing small changes in the gravitational field of the Earth. Since 2009, multiple glaciers along a vast coastal expanse have disappeared in the ocean.

“To date, the glaciers added roughly 300 cubic km of water to the ocean. That’s the equivalent of the volume of nearly 350,000 Empire State buildings combined,” a lead study author Bert Wouters at the University of Bristol said.

“The fact that so many glaciers in such a large region suddenly started to lose ice came as a surprise to us. It shows a very fast response of the ice sheet: in just a few years the dynamic regime completely shifted”, added Bert.

The changes were detected by the CryoSat-2 satellite, operated by the European Space Agency.

The ice loss in the region is so large that it is causing small changes in the gravity field of the Earth. Such a change can be detected by another satellite mission, the Gravity Recovery and Climate Experiment (GRACE).

In the last two decades, the ice shelves in the region have lost almost one-fifth of their thickness, thereby reducing the resisting force on the glaciers.

“To pinpoint the cause of the changes, more data need to be collected. A detailed knowledge of the geometry of the local ice shelves, the ocean floor topography, ice sheet thickness and glacier flow speeds are crucial to tell how much longer the thinning will continue,” Wouters concluded.

With the melting of glaciers and snow due to high temperatures, Mount Everest expedition operators are finding more and more bodies of climbers on and around the world’s highest peak.

More than 200 mountaineers have died on the peak since 1922, when the first climbers’ deaths on the Everest were recorded. Most bodies have remained buried under glaciers or snow, CNN has reported.

“Due to climate change and global warming, snow and glaciers are melting fast, and bodies are being exposed and discovered by climbers,” said Ang Tshering Sherpa, former President of the Nepal Mountaineering Association.

“It’s a serious issue. We are concerned about this as it’s getting worse,” said Sobit Kunwar, an official of the Nepal National Mountain Guides Association. “We are trying to spread information to have a coordinated way to deal with it,” he said.

The association’s Treasurer, Tenzeeng Sherpa, said climate change was affecting Nepal with glaciers, in parts, melting by a meter every year.

“We bring down most bodies. But for those that could not be brought down we pay ours respects by saying prayers and covering them with rocks or snow,” Sherpa said. Pixabay

“We bring down most bodies. But for those that could not be brought down we pay ours respects by saying prayers and covering them with rocks or snow,” Sherpa said.

He lamented poor response of authorities in dealing with bodies found on the mountain. “We have not seen the government taking any responsibility,” he said.

Recovering and removing bodies from higher camps can be both dangerous and expensive. (IANS)
