Mountain ecosystems are among the most fragile and sensitive environments in the world, and they are facing severe pressures due to climate change. These ecosystems provide essential ecological, social, and economic services, including freshwater supply, biodiversity, cultural heritage, tourism, and agriculture. However, rising global temperatures, altered precipitation patterns, melting glaciers, and extreme weather events are profoundly impacting mountain regions. The consequences are multidimensional, affecting biodiversity, water resources, human livelihoods, cultural traditions, and overall ecosystem resilience. One of the most significant impacts of climate change on mountain ecosystems is the accelerated melting of glaciers. Glaciers act as natural reservoirs of freshwater, slowly releasing water that sustains rivers and groundwater throughout the year. In many mountain regions, particularly the Himalayas, the Andes, and the Alps, glaciers are retreating at alarming rates. Initially, this leads to increased river flow and glacial lake formation, which can cause glacial lake outburst floods, threatening downstream communities. In the long term, the disappearance of glaciers will result in reduced water availability, severely impacting agriculture, hydropower generation, and drinking water supplies for millions of people who depend on mountain rivers. This creates a paradox of short-term water surpluses and long-term scarcity. Biodiversity within mountain ecosystems is also highly vulnerable to climate change. Mountains host a wide variety of plant and animal species adapted to specific temperature and altitude conditions. As temperatures rise, species are forced to shift their habitats to higher elevations in search of suitable climates. This upward migration reduces available habitat space and leads to biodiversity loss, as not all species can adapt or migrate fast enough. Alpine plants, for example, may face extinction because there is limited space above their current habitats. Similarly, iconic species such as snow leopards, mountain goats, and red pandas are at risk due to shrinking habitats, reduced prey availability, and increased human-wildlife conflicts. Loss of biodiversity in mountains has cascading effects on ecological balance, nutrient cycles, and the livelihoods of indigenous communities who depend on these species for food, medicine, and cultural practices. The hydrological cycle in mountain ecosystems is being altered by changing precipitation patterns. Climate change is causing shifts from snowfall to rainfall in many mountain regions. Reduced snowfall decreases snowpack accumulation, which is critical for water storage and gradual release in spring and summer. This shift affects seasonal water flow, resulting in either excessive flooding during monsoon or rainfall seasons or reduced water availability during dry months. The irregularity of water flow affects both mountain communities and downstream populations, disrupting agricultural cycles, irrigation practices, and food security. Moreover, permafrost thawing in high-altitude areas destabilizes slopes, leading to increased landslides and soil erosion, which endanger infrastructure, settlements, and ecosystems. Mountain agriculture is also experiencing profound impacts. Farmers in mountain regions are highly dependent on local climate conditions for crop cultivation and livestock rearing. Rising temperatures and changing precipitation patterns have led to unpredictable growing seasons, crop failures, and pest outbreaks at higher altitudes where they were previously absent. Crops such as potatoes, maize, and barley, which are staples in many mountain regions, are under threat due to reduced soil fertility and
