Glacier changes in Langtang Catchment, Central Nepalese Himalaya from the Little Ice Age (∼1815 CE) to 2023 CE

Peer-reviewed journal article by Silwal et al. documenting long-term cryospheric shrinkage across the Langtang catchment, showing a 41.5% reduction in glacier surface area (78.46 ± 4.38 km2) between the Little Ice Age and 2023, accompanied by +0.3°C/decade warming above 4,000 meters elevation.

Method and provenance

Production method
Reconstructs regional glacier outlines and area changes from mapped geomorphological evidence and multitemporal imagery, with historical climate context.
Provenance
Published in Global and Planetary Change (Vol. 264, Article 105555) by an international research team.
Validation
Peer Reviewed Study
Uncertainty
Mapped area-loss uncertainty accompanies the outlines. The source does not establish the previously asserted new lichenometric and cosmogenic cross-validation. Abstract and table percentages differ slightly; approximately 41% is an appropriately qualified summary.
Limitations
Regional historical baseline predating the 2026 event. It does not independently demonstrate source-zone debuttressing, permafrost degradation, or the cause of the later failure.
