The 2023 Mount Everest climbing season is a haunting reminder of how fragile life can be when humans challenge nature.
This year’s climbing season saw 12 deaths and 5 people missing while attempting to conquer Everest – a record high, double the average. Experts say the cause isn’t just extreme weather or the mountain’s inherent risks, but overcrowding and the commercialization of the “roof of the world.”
Shocking Numbers and the Reasons Behind the Tragedy

1. Record Casualties – What Happened?
According to the Himalayan Database, the 2023 climbing season recorded 12 deaths and 5 missing persons, starting from the second week of May. Among them, Australian engineer Jason Kennison, 40, died from altitude sickness and cerebral edema due to oxygen deficiency.
This is a alarming increase from the average of 3-4 deaths per year. Main causes include:
Avalanches and falls
Acute Mountain Sickness (AMS) and exhaustion
Non-AMS illnesses
Exposure to extreme weather conditions
Climber and coach Alan Arnette described this year’s season as a “mess,” noting that one landslide buried three people, and other deaths were due to illness, cold, or exhaustion.
2. The “Death Zone” – A Bottleneck on the Summit
One of the most dangerous factors is the increasing number of climbers. This year, Nepal issued 478 permits for Everest, the highest ever, not counting guides.
Professional guide Allan Cohrs explained: “Large crowds create a huge bottleneck. This increases the risk of frostbite, fatigue, and unnecessary exposure while in the death zone.” When people queue on steep slopes in oxygen-depleted, freezing conditions, deadly time is extended, putting even experienced climbers at risk.
3. Root Causes – Climate Change and Commercialization

Two main reasons for the rising death toll:
Climate change: Unpredictable weather patterns have created more dangerous conditions.
Commercialization of the mountain: Ang Norbu Sherpa, President of the Nepal National Mountain Guide Association, said “too many” permits are being issued, putting environmental pressure on the mountain.
Experts warn Everest is now seen as a “tourist destination” and a playground for wealthy thrill-seekers with little climbing experience. The climbing model has shifted: before, only experienced climbers attempted it, but now many novices also want to reach the summit.
4. The Problem of Guides and Training
Furthermore, few guides in Nepal hold international certifications. Tour companies attract customers with low prices but neglect proper training for guides. As a result, many expedition leaders lack the experience to assess weather conditions, monitor climbers’ health, and track their progress.
El País writer Óscar Gogorza noted: “A good guide won’t let their clients get lost. This partly explains why 5 climbers disappeared this season.”
Conclusion: A Lesson in Humility Before Nature

The 2023 Everest climbing season is a painful wake-up call. Reaching the summit doesn’t guarantee a safe return. The dream of conquering the “roof of the world” is becoming a high-stakes gamble as the number of participants surges without safety measures keeping pace.
The stories of those who disappeared on the mountain, of families waiting for news of their loved ones, remind us that nature always sets limits that human ambition and money cannot overcome. Perhaps it’s time for authorities to reconsider permit policies and ensure that conquering Everest is no longer a dangerous “tourist destination,” but returns to being a true challenge for well-prepared, skilled climbers.
