A look back on the people and events that made headlines in the shadow of Everest
Ever since Tenzing Norgay and Edmund Hillary climbed Mt Everest on 29 May 1953, a lot has changed on the world’s highest mountain. The 60th anniversary of the climb coincides with the announcement this month that the concentration of carbon dioxide in the atmosphere has crossed the 400ppm mark, one-third more than at the start of the Industrial Revolution. Burning fossil fuels and pumping the carbon into the atmosphere has warmed the planet, leading to erratic weather patterns, more intense storms, sea level rise and the melting of the polar ice caps. The Himalayan mountains are melting three times faster than the poles. This panorama of Mt Everest by American filmmaker and climber David Breashears may look scenic, but is an apocalyptic image of glacial retreat.
In the decades after he climbed Everest, Hillary kept returning to Nepal to help with education and health projects. The Sagarmatha National Park became a model for eco-tourism. The per capita income of the Khumbu is now four times the national average. There has also been a dramatic change in mountaineering, with more and more commercial expeditions generating employment for Sherpas.
This season Nepal made Rs 250 million in royalty alone from 30 teams and 335 foreign mountaineers climbing Mt Everest from the south side. The permit fee varies from season to season, the route taken and the number of members in the team. For example a seven member team on the normal South Col route in spring would have to pay $70,000 whereas a seven member expedition on any other route in spring would pay $50,000. If an expedition has more than seven members, it has to pay $10,000 per climber extra.
