The numbers emerging from our mountain valleys are no longer simple environmental metrics. Rather, they represent a human tally recorded in mud and loss. Nearly 800 bodies recovered. Thousands more still missing. We must ask the international community a fundamental question: What was their crime?
I stand before you from the geographical centre of the Himalayas, a nation responsible for a negligible 0.1% of global greenhouse gas emissions. Almost 46% of our country is covered by protective forest canopy. Approximately 94% of our domestic electricity comes from clean hydroelectric power. Furthermore, our move toward electric transport leads global trends, with zero-emission vehicles making up nearly 74% of passenger vehicle imports in recent years.
As a nation, we protect our carbon-absorbing forests, generate grid power from natural river flows, and adopt clean transport technologies at remarkable speeds. Yet today, local people are forced to dig through thick silt, search river channels, and wait beside silent phones for news of missing family members.
To understand what occurred along the Bhote Koshi and Trishuli river valleys, one must look at where it happened and how these forces interact. The Hindu Kush Himalaya known globally as the Earth’s “Third Pole” holds the largest reserve of frozen water outside the polar ice caps. It is also home to eight of the world’s fourteen 8000-meter peaks: Mount Everest (8,848.86 m), Kanchenjunga (8,586 m), Lhotse (8,516 m), Makalu (8,485 m), Cho Oyu (8,188 m), Dhaulagiri (8,167 m), Manaslu (8,163 m), and Annapurna (8,091 m).
This mountain landscape sits upon an active geological collision zone, where the Indian plate drives under Asia at roughly 45 millimetres every year. Major fault lines: the Main Central Thrust (MCT), Main Boundary Thrust (MBT), and Main Frontal Thrust (MFT) run parallel across our geography, creating steep vertical gradients and natural seismic risks. However, human-caused global warming has introduced an additional layer of instability.
Why is this happening now? High-altitude mountain regions warm twice as fast as the global average. This heat thaws permafrost, the frozen earth that holds cliff faces together, while causing glaciers to thin rapidly. Peer-reviewed studies show that regional glacier ice loss accelerated by 65% in recent decades. Consequently, hanging ice sheets lose their structural support, break away, and trigger severe debris flows.
When the collapse happened high above the Lhende Khola, a massive wall of ice and rock dropped vertically into narrow mountain tributaries. Within minutes, this material blocked the river, built up immense pressure, and burst downstream as a high-velocity surge of water, sediment, and heavy boulders.
Whom did this disaster impact most? It hit indigenous mountain communities, hydroelectric workers, local farmers, and local families living along these river channels.
Beyond physical infrastructure, climate change is tearing at the socio-ecological fabric of the Himalayas. For generations, mountain communities have safeguarded these fragile ecosystems using indigenous knowledge systems like the Gurung Thiti and Sherpa Nawa. These local institutions manage high-altitude pastures, protect water springs, and govern the sustainable harvest of valuable medicinal herbs like Yarsagumba and Jatamansi.
Today, warming temperatures and erratic snowfall patterns are drying up high-altitude pastures, causing wild medicinal plants to disappear, and destabilising alpine soils. As indigenous farming calendars break down and mountain springs run dry, rural families lose both their traditional livelihoods and their environmental security.
To build a clean energy future, Nepal invested heavily in run-of-river hydropower projects designed to harness natural water flow without needing massive reservoirs. However, these clean energy plants must sit inside steep valleys to access water energy. When the surge occurred, the river carried thousands of tons of heavy sediment downstream, destroying turbine intakes, tearing down transmission lines, and taking over a dozen hydropower plants offline in a single morning.
Scientific models show that up to two-thirds of Himalayan glacier volume could vanish by the end of this century if global emissions continue unchanged. This loss threatens the long-term water, energy, and food security of nearly 2 billion people living downstream across Asia.
Nepal did not create its economy by burning coal, oil, and natural gas over generations. Who caused the atmospheric warming driving this cryospheric breakdown? Industrialised nations and major fossil-fuel corporations. Yet who pays the immediate human price? The communities whose homes and lives were swept away along our riverbanks.
Therefore, from the high valleys of the Himalayas, we ask the international community these key questions:
What specific casualty count will be required before major emitting nations convert voluntary targets into real reductions?
Where should vulnerable mountain nations turn when clean energy infrastructure built for climate adaptation is wiped out by climate impacts?
When will global finance move beyond conditional loans and deliver direct, grants-based funding for real loss and damage?
How can international frameworks claim to support climate justice while the world’s most vulnerable populations carry the heaviest burden?
Sympathy after a disaster cannot replace structural action. We do not ask for pity or charity. We demand accountability, direct adaptation support, functioning loss-and-damage funds, and emission cuts matching the scale of this crisis. Every person living beneath the Third Pole deserves the basic right to exist safely in their own home.
