A major disaster struck the Himalayas in August 2026 when a massive section of a glacier and surrounding rock collapsed from Langtang Lirung mountain, causing a catastrophic flood of water, ice, and debris. The event resulted in over 1,400 deaths and left more than 5,000 people missing. A team of international scientists, including Professor Bethan Davies from Newcastle University, conducted a detailed analysis and found that the disaster was not caused by a single extreme weather event, but by a combination of long-term climate changes and other factors. The scientists discovered that decades of global warming—largely driven by the burning of fossil fuels—have significantly altered the high-altitude environment. Rising temperatures have caused glaciers to shrink and permafrost—frozen ground that helps stabilize mountain slopes—to thaw. This thawing weakens the structural integrity of mountain walls. Additionally, the freezing threshold, or the altitude where temperatures remain at or below 0°C, has risen by about 100 meters (328 feet) per decade, exposing more frozen ground to higher temperatures. A major 2015 earthquake may have further weakened the mountain slopes, increasing the risk of collapse. The analysis also showed that the months immediately before the disaster were the warmest on record in the region. High snowfall in late 2025 led to increased meltwater, which may have added pressure to the unstable slopes. Scientists estimated that climate change has contributed about 1.5°C of warming during the critical months of July and August 2026, and has raised average temperatures by 2°C annually in the area. Despite early warning systems and disaster preparedness plans in place in Nepal, the scale of this disaster exceeded the physical limits of adaptation, highlighting the growing challenges of responding to increasingly severe climate-related events. The study, conducted by World Weather Attribution, involved experts from various fields analyzing the multiple factors that contributed to the collapse. Researchers used established scientific methods to determine the role of climate change in raising temperatures and affecting precipitation patterns. Scientists emphasized that the disaster reflects a broader transformation of high-mountain environments, increasing risks in areas already prone to seismic activity. The findings underscore the urgent need for global action to reduce emissions and support vulnerable communities facing the unavoidable impacts of climate change.
