Shifting Climbing Seasons
The impact of climate change on Nepal's mountain expeditions is profoundly evidenced through the shifting of traditional climbing seasons, affecting both the pre-monsoon and post-monsoon periods, which are critical for expeditions in the Himalayas. These shifts have altered the landscape of mountain climbing, affecting day and night temperatures, which are crucial for planning and executing expeditions safely and successfully.
Pre-Monsoon Season (Spring)
- Period: Late March to May
- Day Temperatures: At base camp, day temperatures can vary from 5°C to 10°C (41°F to 50°F), creating relatively warmer conditions for climbing preparations. However, as climbers ascend, temperatures can drop significantly, especially above 4,000 meters (13,123 feet), where daytime temperatures might hover just above freezing.
- Night Temperatures: Night temperatures at base camp can drop to -5°C to 0°C (23°F to 32°F). In higher elevations, temperatures at night can fall below -20°C (-4°F), particularly in the death zone, where they can plummet to -25°C to -30°C (-13°F to -22°F).
Post-Monsoon Season (Autumn)
- Period: September to November
- Day Temperatures: Similar to the pre-monsoon season, base camp day temperatures can range from 5°C to 10°C (41°F to 50°F). This season typically offers clearer skies and more stable weather, but climate change has introduced more unpredictability.
- Night Temperatures: Night temperatures at base camp during this season are slightly warmer than in the pre-monsoon period, ranging from -5°C to 5°C (23°F to 41°F). However, in higher altitudes, temperatures after sunset can quickly drop to -20°C (-4°F) or lower, especially in areas above 8,000 meters.
Impact of Climate Change
Climate change has led to a noticeable shift in these seasons, with warmer temperatures extending further into what would traditionally be the colder months. This affects not only the physical conditions of the glaciers and snowpack but also the ecosystem and wildlife dependent on these temperature cycles.
- Glacier Melting and Route Instability: Increased temperatures lead to accelerated glacier melting, affecting the stability of climbing routes and increasing the risk of avalanches and icefalls.
- Weather Unpredictability: Climbers face increased difficulty in predicting weather windows for safe ascents, as traditional patterns become less reliable. Unexpected weather changes, including sudden storms and temperature spikes, pose additional risks.
- Adaptation and Flexibility: Expeditions must now employ more flexible planning, with contingencies for weather-related delays and route changes. This includes closer monitoring of weather forecasts and adjusting climbing schedules to accommodate the shifting seasons.
We are acutely aware of these challenges and remain committed to providing safe, responsible, and unforgettable climbing experiences.

Melting Glaciers and Icefalls
One of the most visible and concerning effects of climate change on Nepal's mountain expeditions is the melting of glaciers and icefalls. These icy behemoths, which have stood as silent witnesses to centuries of climatic shifts, are now retreating at an unprecedented rate. We recognize the gravity of this situation and its implications for the future of Himalayan mountaineering.
-
Accelerated Glacier Retreat: The Himalayas, home to the largest concentration of glaciers outside the polar regions, are experiencing rapid glacier melt. This not only alters the landscape but also affects water sources downstream, impacting millions of people.
-
Instability of Icefalls: Icefalls, such as the notorious Khumbu Icefall on the route to Mount Everest, are becoming increasingly unstable. These dynamic structures are formed by glaciers as they move and crack, creating a maze of ice towers and crevasses. The warming climate exacerbates the movement and melting of these icefalls, making them more dangerous to navigate.
-
Changes in Climbing Routes: The retreat of glaciers and the instability of icefalls necessitate constant reassessment and alteration of established climbing routes. What was once a stable path may now be fraught with new crevasses or unstable ice, requiring climbers to adapt to these changes.
-
Increased Risk of Avalanches and Icefalls: The melting of glaciers and the destabilization of ice structures lead to an increased risk of avalanches and icefalls, posing significant dangers to climbers, sherpas, and porters on these expeditions.
-
Impact on Local Communities: The melting glaciers also threaten the livelihoods of local communities that depend on glacial waters for agriculture, drinking, and hydroelectric power. As glaciers retreat, the risk of glacial lake outburst floods (GLOFs) increases, posing a threat to villages and infrastructure.
We are deeply committed to mitigating the impacts of these environmental changes through sustainable expedition practices. We advocate for increased awareness and action on climate change, aiming to preserve the majestic beauty and integrity of Nepal's mountainous landscapes for future generations.

Formation of Glacial Lakes
The rapid formation of glacial lakes due to climate change is a critical concern for the sustainability and safety of mountain expeditions in Nepal. As glaciers retreat, they often leave behind significant amounts of meltwater that accumulates in depressions on the landscape, forming glacial lakes. We are acutely aware of the challenges and risks these emerging lakes pose to climbers, local communities, and the overall integrity of the Himalayan ecosystem.
-
Increased Risk of Glacial Lake Outburst Floods (GLOFs): One of the most immediate dangers associated with the formation of glacial lakes is the potential for Glacial Lake Outburst Floods. These catastrophic events occur when the natural dam, often composed of ice or moraine, holding back the lake water fails, releasing massive volumes of water downstream. The impact can be devastating, destroying villages, bridges, and trekking routes.
-
Alteration of Climbing Routes: The expansion and formation of new glacial lakes may necessitate the rerouting of traditional climbing paths. As lakes expand, they can cut off access to established routes or create new hazards that climbers must navigate, adding complexity and unpredictability to expeditions.
