Tenzing Norgay Biopic Highlights Everest's Changing Landscape

A biopic about Tenzing Norgay's life has recently been released, shedding light on his remarkable first ascent of Everest in 1953.

The film beautifully captures Norgay's humility and deep connection to nature and the mountains through its cinematography. The sweeping shots of the majestic mountain landscapes are awe-inspiring, drawing attention away from the main characters at times.

As a mountaineer and glaciologist myself, I couldn't help but reflect on how much things have changed since Norgay's time on Everest. The film made me wonder what he would think if he could return to the mountain today, considering all the developments that have taken place over the years.

Everest Base Camp has undergone a significant transformation in recent decades. Gone are the days of single large expeditions; instead, the Nepalese government now issues multiple permits each year.

The conditions at Base Camp have changed dramatically since 1953. Gone are the days of thick snow and stable ground; today, climbers face a vastly different landscape.

A study using declassified spy satellite imagery revealed that the rate of ice mass loss in the Himalayas doubled between the 1970s and the 2000s. Specifically, researchers found that between 2000 and 2016, the region experienced an accelerated rate of thinning at an altitude equivalent to Base Camp.

The Khumbu Glacier, which provides access to Everest's Base Camp and marks the start of the real climbing, has also undergone significant changes. Initially around 150 meters thick in the area below base camp, its thickness is now dwindling at a rapid pace.

This rate of thinning would result in the glacier losing about a third of its volume within approximately 73 years, exposing unstable rock and increasing the risk of landslides. Moreover, this accelerated loss has continued beyond 2016, with recent data indicating even higher rates of mass loss across the Himalayas.

Recent Google Earth imagery from 2021 shows extensive development of lakes on the Khumbu Glacier's surface, a clear sign that it is experiencing significant decline. These lakes absorb more solar radiation than the surrounding ice, further accelerating melting and contributing to the glacier's rapid deterioration.

The rapid deterioration of glaciers in the European Alps has become a pressing concern, with alarming rates of melting threatening the very existence of these natural wonders.

In just two years, from 2022 to 2023, glaciers in the Swiss Alps lost a staggering 10% of their volume, raising fears that they could disappear entirely within the next 20 years if current trends continue.

The impact is not limited to the loss of glacial mass; warmer temperatures have also made it increasingly hazardous for climbers and hikers. Mountain huts have been forced to close, and guides have stopped taking clients up popular routes due to the risk of rockfall triggered by melting ice.

Many other routes in the Alps are being avoided due to the treacherous conditions caused by high temperatures and subsequent rockfall. The first six months of 2026 were among the warmest on record, with far-reaching consequences for glaciers and the frozen landscape as a whole.

The situation is eerily reminiscent of the catastrophic flood that recently occurred near the Nepal-Tibet border, which has been linked to rising regional temperatures, weakening permafrost, and increased glacier melt rates.

The north face of the Eiger, one of the most iconic routes in the Alps, has undergone significant changes in recent years. The second icefield, a crucial part of the original 1938 route, is now non-existent and climbing the route during summer is no longer recommended due to hazardous conditions.

Climbers are advised to tackle the north face during late winter or early spring to avoid the dangers posed by rotten rock and unpredictable weather patterns. This shift in climbing seasons reflects the rapidly changing landscape of the high mountains, with many experienced mountaineers witnessing unprecedented transformations on famous alpine routes.

The impact of climate change is expected to be severe, with glaciers in regions such as the European Alps, western Canada, and Scandinavia projected to lose up to 90%–100% of their mass by 2100. This loss will have far-reaching consequences for mountain ecosystems, tourism, and natural hazards in these once-pristine environments.

The timeline for this drastic change is alarming, with the predicted losses occurring within a mere 74 years. For comparison, this period roughly spans the time between the first ascent of Everest and the present day, underscoring the urgency of addressing climate-related concerns affecting mountainous regions worldwide.

The majestic beauty of Mount Everest has been irreparably altered by human activity over the years. Global heating and irresponsible expedition behavior have taken their toll on the mountain's pristine landscape.

Expeditions that visit EBC today leave behind a trail of destruction, further exacerbating the damage caused by climate change. The once-pristine environment is now scarred by litter, human waste, and other signs of neglect.

The changes to the mountain and its surroundings would likely be disheartening for Tenzing Norgay, who made history with his first ascent of Everest alongside Sir Edmund Hillary.
