Glaciers are fundamental components of the global cryosphere, acting as critical freshwater reservoirs that regulate river discharge, support ecosystems, and sustain billions of people downstream. This project investigates the profound impacts of anthropogenic climate change on glacial hydrology, arguing that rising global temperatures are not merely causing ice melt, but are systematically dismantling a stable, natural water-regulation system. This research employs a case study analysis of the Himalayan region, combining a review of the current scientific literature with trend analysis of satellite imagery (Landsat, 1990-2020) to visualize decadal-scale glacier retreat.

The findings confirm a direct correlation between increasing regional temperatures and accelerated glacial mass loss, leading to a shift in hydrological regimes. This manifests as a dangerous transition from a period of increased meltwater (peak water) to an eventual state of significant water scarcity. The project further analyzes the cascading consequences of this shift, including heightened risks of glacial lake outburst floods (GLOFs), altered sediment transport, and severe threats to agricultural and municipal water security downstream.

This unraveling of a millennia-old hydrological balance presents a paramount challenge for the 21st century. This study concludes that while immediate local adaptation strategies such as enhanced water management and early warning systems are urgently required, they are ultimately insufficient. The only permanent solution to mitigating long-term, catastrophic water loss lies in global commitment to aggressive climate change mitigation policies aimed at reducing greenhouse gas emissions and preserving the remaining cryosphere.
