Everest Base Camps to remain despite of Climate Change Threat

Anita Douglas

 

Plans to relocate the iconic Everest Base Camp in Nepal have hit a roadblock due to opposition from the Sherpa community and mountaineering operators. Last June, Nepal's tourism ministry announced intentions to move the base camp to a lower elevation due to the threats posed by global warming and the thinning Khumbu glacier. However, after facing resistance, the idea has been put on hold. This article explores the various perspectives surrounding the issue, highlighting the concerns raised by the Sherpa community, mountaineering operators, and scientists, as well as the environmental challenges posed by the melting glacier.

​

Opposition from the Sherpa Community:

​

The Sherpa community, integral to the mountaineering industry, vehemently opposes the relocation of the Everest Base Camp. Consultations with the mountaineering industry revealed that over 95% of attendees rejected the idea. According to Mingma Sherpa, chair of Khumbu Pasanglhamu, a rural municipality covering the Everest region, there is no support within the community for moving the base camp. The lack of a viable alternative location adds to their concerns.

Ang Norbu Sherpa, president of the Nepal National Mountain Guides Association, echoed these sentiments, questioning the need for relocation after the base camp's 70-year history. He stressed the necessity of a comprehensive study to identify a suitable alternative before proceeding with any changes. Sudan Kirati, Nepal's tourism minister, also expressed a lack of urgency regarding the issue, citing the absence of widespread interest or concern.

​

Implications of Glacial Thinning and Climate Change:

​

Scientists have observed rapid melting of the Khumbu glacier due to global warming and rising temperatures, creating risks for climbers passing through Everest Base Camp. A 2018 study by Leeds University researchers revealed that the segment near the base camp was losing one meter of thickness annually. Moreover, increasing temperatures have led to the expansion and merging of ponds and lakes on the glacier's surface, making conditions more challenging for mountaineers.

Proponents of the base camp relocation argue that moving it to an area without glaciers would mitigate risks associated with the accelerated glacial meltdown. Adrian Ballinger, founder of Alpenglow Expeditions, emphasized the potential increase in avalanches, icefalls, and rockfalls, making the current base camp susceptible to dangerous incidents. However, without a clear alternative location, the Sherpas and mountaineers remain unconvinced.

​

Challenges of the Khumbu Icefall:

​

The Khumbu Icefall, a treacherous section of the climb, is one of the primary reasons the Sherpa community opposes moving the base camp. Many Sherpa climbers argue that the current location allows them to start their ascent early in the morning, reducing the dangers posed by the icefall. The icefall, which rapidly descends the mountain, is riddled with hidden crevasses, collapsing seracs, and frequent avalanches and rockfalls.

Mingma Sherpa points out that if the base camp is moved to a lower elevation, climbers would face an additional three hours of walking, delaying their journey through the Khumbu Icefall. Recent tragic events, such as the deaths of three Sherpa climbers during an avalanche while ferrying gear, underscore the dangers presented by the icefall.

​

Crowding at Base Camp and Environmental Concerns:

​

While the opposition to relocating Everest Base Camp grows, there is consensus within the mountaineering community that the camp's population has become unsustainable. Nepal issued a record 478 Everest climbing permits this season, resulting in overcrowding with over 1,500 people on the mountain, including support staff. Concerns about unregulated growth and its impact on the already fragile environment are mounting.

​

Dambar Parajuli, president of the Expedition Operators' Association Nepal, highlights the doubling in size of the base camp over the years and the presence of luxury services like massage parlors, which he argues contradict the purpose of mountaineering. Parajuli and others have urged the government to establish strict guidelines to preserve the sanctity of the base camp.

Minister Kirati acknowledged these concerns, pledging to address the issue. He emphasized that base camp should not resemble a tourist market and stated the government's intention to enforce regulations during an upcoming inspection. Striking a balance between the economic benefits of mountaineering and the preservation of the environment remains a critical challenge.


The plans to relocate Everest Base Camp have been delayed due to opposition from the Sherpa community, a lack of viable alternative locations, and concerns about the dangers posed by the Khumbu Icefall. Climate change and glacial thinning present real risks to climbers, but without a clear solution, the idea of moving the base camp remains contentious. In addition, overcrowding at the base camp and unregulated growth threaten the fragile environment of the region. Balancing the demands of mountain tourism with the preservation of the natural ecosystem remains a significant challenge for both the Nepalese government and the mountaineering community.
