Climate change is causing the highest glacier on Mount Everest to melt at a rapid pace, a new study has found, News.Az reports citing BBC. 

Researchers led by the University of Maine found that the South Col Glacier has lost more than 180ft (54m) of thickness in the last 25 years.

The glacier, which sits around 7,906m (25,938 ft) above sea-level, is thinning 80 times faster than it first took the ice to form on the surface.

The rate of decline has been blamed on warming temperatures and strong winds.

Scientists leading the study found that since the 1990s, ice that took around 2,000 years to form has melted away.

They also noted that the glacier's thick snowpack has been eroded, exposing the underlying black ice to the sun and accelerating the melting process.

Dr Mariusz Potocki, one of the study's lead researchers, said that the findings suggested "that the South Col Glacier may be on the way out - it may already be a 'relic' from an older, colder, time".

Another author of the report, Dr Tom Matthews, a climate scientist from Kings College London, observed to the BBC that there had been no single change in the region's climate to cause the surge in melting.

"Instead, the steady uptick in temperatures eventually pushes the glacier across a threshold, and suddenly everything changes," he said.

While glacier melt has been widely studied, the impact of climate change on glaciers at this height has not previously been studied.

A team of 10 scientists visited the glacier, where they installed the world's two highest weather monitoring stations and extracted samples from a 10-meter-long (around 32 feet) ice core.
