One full report and 11 digests were used, with claims corroborated across multiple sources. - Craft 60 of 100, higher is better. The full report provides specific details on the disaster's unfolding and scientific findings. - Hype 40 of 100, lower is better. Headlines and digests use strong language like 'deadly' and 'catastrophic' but are generally supported by the content.

A mountain slope collapsed and flash floods swept through Nepal and Tibet, resulting in nearly 1,400 deaths and over 5,000 people missing. Scientists determined that climate change, including warming temperatures, glacier retreat, and permafrost thaw, destabilised the slope. The collapse released energy equivalent to a magnitude 5.2 earthquake and generated a flood that travelled at an average speed of 170 kilometres per hour. July and August 2026 were the warmest months on record in the area, with temperatures significantly above the 10-year average. Researchers with World Weather Attribution concluded that the disaster was difficult to adapt to due to its complex and rapidly developing nature. Nepal's early warning systems were outpaced by the flood, with the first SMS warning sent 38 minutes after the initial collapse, by which time the flood had already reached the border. ## Disagreement on the scale of missing persons Reports differed on the number of people missing. Tempo.co stated that over 5,000 people remained missing. The Times of India reported at least 6,600 missing, while CNBC-TV18 stated 6,669 missing. EnviroNews Nigeria reported over 5,000 missing. ## What the coverage left out None of the left, centre, or right-rated reports mention the energy released by the collapse equivalent to a magnitude 5.2 earthquake. None of the left, centre, or right-rated reports mention the speed of the floodwaters reaching 170 km/h. None of the left, centre, or right-rated reports mention the specific findings of World Weather Attribution regarding the disaster's complex and rapidly developing nature making it difficult to adapt to. ## Who covered it Shares of the 10 covering outlets with a published leaning rating: - Left: 10% (1) - Centre: 30% (3) - Right: 60% (6) 3 of 13 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-09-17T04:00:52.882103+00:00. **Coverage watch:** developing. Checked 3 times; 0 checks found a material change. Most recently checked 2026-09-17T04:45:15.795Z. ## How the sides framed it ### Left - The left-rated report from Tempo.co led with the death toll and the number of missing people. It detailed the scientific findings that climate change, including warming temperatures, glacier retreat, and permafrost thaw, destabilised the slope. The report quoted Walter Immerzeel, a mountain hydrologist, stating the event was not a single trigger but a combination of processes over years. It also quoted Friederike Otto, professor of climate science, who said that without faster action on fossil fuel emissions, more disasters of this scale would occur. The report highlighted that the disaster exceeded the limits of adaptation and that Nepal's early warning systems were outpaced. ### Centre - The centre-rated reports from Deutsche Welle and RTÉ both led with the link between climate change and the collapse. Deutsche Welle stated that decades of warming helped set the disaster in motion. RTÉ reported that climate change contributed to thinning glaciers and thawing frozen ground that held the mountain together. Both reports mentioned that the collapse killed nearly 1,400 people and left thousands missing. ### Right - The right-rated reports from Times of India, CNBC-TV18, Free Malaysia Today News, Latestly, Le Journal de Montreal, and Le Journal de Quebec all led with the certainty of climate change's role in the disaster. Times of India and CNBC-TV18 reported death tolls of over 1,400 and missing figures of 6,600 and 6,669 respectively. Free Malaysia Today News mentioned that July and August 2026 were the warmest months recorded locally and that heavy snowfall in late 2025 increased meltwater. Le Journal de Montreal and Le Journal de Quebec stated the flood was the result of climatic factors. Latestly also reported that climate change worsened the collapse. **Provisional coverage gap:** left. The watch is not closed, so this is not yet a settled blindspot finding. ## Factuality profile of the covering outlets These are published factuality ratings of the outlets, not a verdict on whether this story or its claims are true. - mixed: 4 - high: 4 - unknown: 3 - veryHigh: 2 ## Verification scope This page compares coverage and scores the source reporting.

Over 5,000 people were reported missing across the affected regions. **What caused the mountain slope collapse?** Scientists determined that climate change, including warming temperatures, glacier retreat, and thawing permafrost, destabilised the mountain slope. These factors combined with geological conditions to trigger the catastrophic event. **How fast were the floodwaters moving?** The floodwaters generated by the collapse moved at an average speed of 170 kilometres per hour. The initial collapse released energy equivalent to a magnitude 5.2 earthquake. **Were there any early warning systems in place?** Nepal had early warning systems, but they were outpaced by the speed of the flood. The first SMS warning was sent 38 minutes after the initial collapse, by which time the flood had already reached the border. --- MediaBias News — https://mediabias.news.
