Super Sherpa Apa Sherpa — who has climbed Everest a record 21 times — plans to trek the length of Nepal's newly launched Great Himalayan Trail to raise awareness about the impact of climate change.

The relatively new trail cobbles together various legs of the Himalayan range, which is home to Everest, K2 and more than 100 peaks exceeding 21,000 feet in height.

“Apa Sherpa, 52, will be accompanied by two-time Everest climber Dawa Steven Sherpa on the grueling 1,700 km (1,062 mile) 120-day walk,” Reuters reported, in its deadpan style.

Reuters quoted Aga Sherpa as saying:

During the walk we will see the challenges faced by the local people in dealing with the effects of climate change on the remote and poor foothills of Himalayas.

You may recall the controversy over the melting glaciers — which climate change activists had claimed were shrinking far more rapidly than the evidence supports.

But there's little doubt that there have been significant changes already due to warmer temperatures. And perhaps the observations of “regular guys” (okay, topping Everest 21 times isn't that regular) will show some sense behind the science.
