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.

According to studies, glaciers in the Everest region are melting and thinning.

“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)

New automotive technology that promises enhanced fuel efficiency may have a serious downside, including significant climate and public health impacts, a new study suggests.

The gasoline direct injection (GDI) engine is one of the most prominent technologies car manufacturers adopted to achieve the fuel economy and carbon dioxide emission goals established in 2012 by the US Environmental Protection Agency.

While this technology is credited with boosting fuel efficiency and reducing CO2 emissions, GDI engines produce more black carbon aerosols than traditional port fuel injection engines, according to the study published in the journal Environmental Science and Technology.

“Even though emissions from gasoline vehicles constitute a small fraction of the black carbon in the atmosphere, the vehicle emissions are concentrated in regions with high population densities, which magnifies their effect,” said study researcher Rawad Saleh, Assistant Professor at University of Georgia in the US.

The market share of GDI-equipped vehicles increased from 2.3 per cent in model year 2008 to 51 per cent in model year 2018. The EPA projects 93 per cent of vehicles in the US will be equipped with GDI engines by 2025. According to the study, researchers predicts the increase in black carbon emissions from GDI-powered vehicles will fuel climate warming in urban areas of the US that significantly exceeds the cooling associated with a reduction in CO2.

In addition, they believe the shift will nearly double the premature mortality rate associated with vehicle emissions, from 855 deaths annually to 1,599. The researchers estimate the annual social cost of these premature deaths at $5.95 billion. The increase of black carbon is an unintended consequence of the shift to GDI-equipped vehicles that some scientists suspected was based on experimental data, according to the researcher.

“This study is the first to place these experimental findings in a complex modeling framework to investigate the trade-off between CO2 reduction and an increase in black carbon,” Slah said. While previous research has reported the shift to GDI engines will result in net benefits for the global climate, the researchers said that these benefits are rather small and can only be realized on timescales of decades.

Meanwhile, the negative impact of black carbon can be felt instantaneously, they added.

“Our research shows the climate trade-off is much different on the regional scale, especially in areas with high vehicle densities. In these regions, the climate burden induced by the increase in black carbon dominates over the climate benefits of the reduction in CO2,” said Saleh. (IANS)
