Has Climate Change affected the Number of Climbing Days available on Mount Everest Each Year?

Just as the rest of the world is feeling the harsh impacts of climate change, so is Mount Everest, the tallest peak in the world. Climbing Everest is considered the pinnacle of climbing achievements for mountaineers around the globe. However, changing climate patterns have jeopardized the number of climbing days available each year, thus posing a significant challenge for adventurous climbers.

Climate Change and Mount Everest

Experts have pointed out that rising global temperatures, increased precipitation, fluctuating jet stream patterns and other climate change impacts are directly affecting the climbing conditions on Everest. A 2019 study conducted showed a considerable decrease in the snow and ice cover of the region, which has serious consequences for future climbing endeavors.

The Shrinking Everest Climbing Window

One of the most evident impacts of climate change on Mount Everest is the shrinking of the climbing window. Traditionally, Everest could be climbed during the two brief periods of May and September, when the jet streams shift away from the peak. However, due to climate change, these windows are becoming smaller, reducing the number of climbing days.

Climate change is causing an anomalous and erratic weather pattern characterized by increased wind velocity and sudden snowfall even during these windows. Such climatic inconsistencies make the already dangerous endeavor even riskier, forcing climbers to abandon their attempts. This shrinkage of the climbing window is leaving less opportunity for climbers to make their ascents.

Increased Avalanche Risk

Moreover, climate change has been associated with a heightened risk of avalanches and landslides on Everest. The warming temperatures are melting glaciers and the permafrost, which holds the mountain together. This is destabilizing the slopes, thereby introducing a higher risk of landslide and avalanches, further chipping away at the number of safe climbing days on Everest each year.

A Future with Fewer Climbing Days

With the persistent progression of climate change, scientists predict that the number of climbing days on Everest will continue to decline in the future. This represents not only a significant loss for the international mountaineering community but also for local communities who rely on the revenue from tourism and climbing expeditions.


In conclusion, the impact of climate change on Mount Everest is undeniably severe. It is our collective responsibility to curtail our carbon emissions and limit global warming. By doing so, we can protect not only our mountains but also the delicate ecosystems and majestic beauty that they harbor.


Q1: How is climate change affecting Mount Everest?

Climate change is affecting Mount Everest by altering weather patterns, increasing temperatures, and destabilizing slopes due to melting permafrost. These changes are leading to a decrease in safe climbing days.

Q2: What are the dangerous conditions caused by climate change on Everest?

Climate change introduces hazardous conditions like erratic and uncontrollable weather patterns, higher risk of avalanches or landslides due to slope destabilization, and shrinking climbing windows.

Q3: What does the future look like for climbing Everest?

If climate change continues unchecked, the future of climbing Everest could be in jeopardy as safe climbing windows could become more infrequent and unpredictable.

Q4: Why is Mount Everest’s climate important to local communities?

Mount Everest’s climate is crucial to local communities as it affects tourism and climbing. These activities generate significant revenue for the local economy.

Q5: What can be done to mitigate the impacts of climate change on Everest?

Global efforts towards reducing carbon emissions can help to mitigate the impacts of climate change. It is essential to pay attention to sustainable and responsible mountaineering to protect Everest’s delicate ecosystem.
