Solukhumbu: Nepal Once known for its dazzling white peaks, icy winds and sky-piercing summits, the Khumbu region is now witnessing rapid and unsettling change. Locals say the snow that defined their landscape for generations is disappearing at an alarming pace.

“It feels like a different era has begun,” said elderly resident Pasang Sherpa of Khumbu. “Since childhood, the mountains were always white. Now half of them look like bare black rock. The change is happening right before our eyes.”

Until two decades ago, upper regions including Namche, Khumjung, Tengboche, Lobuche and Gorakshep remained snow covered throughout the year. Today, snowfall periods have shortened, and even the snow that does fall melts far more quickly, said local resident Lamakaji Sherpa.

Mount Everest, Lhotse, Nuptse, Ama Dablam and Thamserku once blanketed in white now show large, exposed sections of dark rock. The unusual sight surprises tourists, but locals say it has become a new normal.

“We only realized the severity after visitors repeatedly questioned us,” said Khumjung resident Fudoma Sherpa. “The process is accelerating, and we feel helpless. Who do we ask for answers, and how do we stop it?”

According to former Sagarmatha National Park conservation officer Bhumi Raj Upadhyay, the thinning of snow cover is a direct result of rising temperatures. Scientists estimate that temperatures in high Himalayan regions have risen by around 1.5 °C since the 1970s.

Meteorologist Rajan Thapa says the darkening mountain surfaces have several causes: rapidly melting snow, exposed rock from landslides, dry snow patches turning into bare slopes, black carbon deposition, and increasing human activities in the region.

Local residents have also noticed extreme weather shifts. “Winter used to be harsh but bearable,” said Pema Sherpa of Jorsalle. “Now the cold cuts into your bones, and even summers are so warm that you sweat while standing at the foot of the mountains.”

Growing Threats: Floods, Glacial Lakes and Falling Rocks

The region has already witnessed deadly consequences. On a Friday last monsoon, a massive flood in Thame Khola swept away more than 20 houses, damaged schools, health posts, trekking routes, farms and even a hydropower project. The main trekking trail from Phakding to Namche was severely eroded.

Tourism the backbone of Nepal’s economy and the lifeline of Khumbu faces growing threats as climate stress intensifies. Glacial lakes in the region, including Fereche, Imja and Khumbu basins, are expanding rapidly. Imja Lake alone has grown by 65% in the past two decades, a sign of accelerating melt.

“We once heard stories of glacial lake outburst floods,” said local resident Pashi Lama. “Now we live in constant fear. As the lakes grow, our villages, bridges and trails are all at risk.”

Changing Lives and Landscapes
Traditional Himalayan life from herding patterns to water use and farming is shifting as snow declines. Streams and rivers that once ran throughout the year are now drying during winter. The Dudh Koshi and Imja Khola swell only during monsoon, while dry season water scarcity has become common.

Trekking guides say unpredictable weather has made routes more hazardous, with increased risk of rockfalls, landslides and avalanches. “The plans we made in the past don’t work anymore,” said guide Bal Darnal. “The weather is too uncertain, and we must take far more precautions for tourists.”

Climbers fear the region’s identity itself could be at stake. “These mountains define who we are,” said mountaineer Speedkaji Sherpa. “If this continues, the Khumbu we know may disappear.”
