Why in News: May 29, 2026 marks the 73rd anniversary of the first successful summit of Mount Everest (8,848.86 m) by New Zealand mountaineer Edmund Hillary and Sherpa Tenzing Norgay at 11:30 AM IST on May 29, 1953, as part of the British Mount Everest Expedition led by Col. John Hunt. The route taken was via the South Col on the Nepal side. The day is observed informally as “Everest Day” in Nepal.

The Climbers — Quick Background

Edmund Hillary (1919-2008)

  • New Zealand-born; trained as a beekeeper.
  • Served in Royal New Zealand Air Force during WWII (Pacific theatre).
  • Joined British expedition based on his Himalayan experience.
  • Knighted on the day Queen Elizabeth II was crowned (June 2, 1953).
  • Later climbed many other peaks; co-led the 1958 Commonwealth Trans-Antarctic Expedition reaching the South Pole.
  • Founded the Himalayan Trust for Sherpa welfare (1960).
  • New Zealand’s High Commissioner to India, Nepal, Bangladesh (1985-1988).

Tenzing Norgay (1914-1986)

  • Born Namgyal Wangdi in Tengboche, Nepal (some accounts say Tibet); later took Sherpa name Tenzing Norgay.
  • Resided in Darjeeling, British India; Indian citizen post-1947.
  • Veteran of multiple prior Everest attempts (Swiss expeditions of 1952 came within 240 m of summit).
  • Received Padma Bhushan (1959) from Govt of India.
  • Founding director of the Himalayan Mountaineering Institute (HMI), Darjeeling (1954-1976).
  • Refused British knighthood; accepted George Medal.
  • Tenzing-Hillary “who summited first” question: by mutual agreement they always said they reached the top together.

Indian Connections — Beyond Tenzing

Tenzing Norgay Indian citizen at time of summit; Padma Bhushan 1959
Avtar Singh Cheema First Indian to summit Everest, May 20, 1965 (with Indian Army expedition led by Lt Col Mohan Singh Kohli)
Bachendri Pal First Indian woman to summit Everest, May 23, 1984; Padma Shri 1984, Padma Bhushan 2019
Arunima Sinha First Indian female amputee to summit, May 21, 2013
Anshu Jamsenpa Indian woman with most ascents — 5 times by 2017
Indian Army Mountaineering Institute (IMA) Multiple expeditions
Himalayan Mountaineering Institute (HMI), Darjeeling Founded 1954; trained generations of Indian mountaineers

Threats to the Mountain in 2026

Climate Change

  • Khumbu Glacier retreating — base camp moved ~50 m in 5 years.
  • Western Cwm temperature warming — ice-fall instability.
  • Snowfall decreasing at high altitude; ice exposed.
  • Climbing windows narrowing — May “good weather” period more variable.

Crowd and Commercial Pressures

  • ~600 climbers/year reach summit during May season (Nepal side).
  • “Traffic jams” at Hillary Step and at the summit ridge.
  • 2019 image of ~300-person queue near summit became symbolic.
  • Many climbers under-prepared; reliance on Sherpas, fixed ropes, supplemental oxygen.
  • Royalty fee (Nepal) = USD 11,000/permit (peak season).

Environmental Degradation

  • Estimated 50+ tons of garbage on the mountain.
  • Nepal Army-led “Mountain Cleanup Campaign” since 2019.
  • Mandatory waste-return policy — climbers must bring back 8 kg of garbage.
  • Human waste disposal issues at base camp.

Geopolitical

  • Border between Nepal and China runs along summit ridge.
  • China’s Tibet (Northeast Ridge) route opens/closes based on political climate.

The Hindu Kush–Himalaya (HKH) Cryosphere Context

Parameter Detail
HKH region covers 8 countries — Afghanistan, Pakistan, India, Nepal, Bhutan, China, Myanmar, Bangladesh
Glaciers ~54,000 — third-largest ice store outside polar regions
People dependent on HKH river systems ~1.6 billion (Indus, Ganga, Brahmaputra, Yangtze, Yellow, Mekong systems)
HKH glacier mass loss (2010-19) ~65% faster than 2000-09 (per ICIMOD HKH Report 2023)
Projected loss by 2100 30-50% under 1.5°C scenario; 80% under higher warming
Implications Initial increase in runoff (peak around 2050) followed by sharp decline; water security risk for 1+ billion people

Wider Significance

  • Cultural milestone — Everest summit is a global symbol of human aspiration and limit.
  • India-Nepal-China linkage — three civilisations meet at the summit ridge.
  • Soft power — mountaineering as people-to-people diplomacy.
  • Climate adaptation — Himalayan ecosystem services to a quarter of humanity.
  • Tourism economy — Nepal’s foreign exchange depends substantially on Everest tourism.

Way Forward

  • Strict permit caps — Nepal’s recent talk of capping climbers.
  • Mandatory experience requirement — must have summited a 7,000+ m peak before attempting Everest (Nepal MoU 2024).
  • Carbon-neutral climbing — eco-base camps, solar-powered shelters.
  • Cryosphere monitoring — ICIMOD + India MoES + China cooperation needed.
  • South Asian Mountain Initiative — pan-regional mountain ecology framework.
