Understanding the Himalayan Glaciers: The Third Pole of Our Planet

The Himalayan glaciers represent one of the most critical freshwater resources on Earth, often referred to as the "Third Pole" due to their massive ice reserves. The Himalayan mountain range is home to the world's third-largest amount of glacier ice, after Antarctica and the Arctic. These magnificent ice formations stretch across the Hindu Kush Himalayan region, extending over 2,000 kilometers across South Asia and encompassing parts of Afghanistan, Bangladesh, Bhutan, China, India, Nepal, and Pakistan.

The Hindu Kush Himalayan region is the location of several of Asia's great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. However, more recent assessments suggest the number of people dependent on these glaciers is even higher. Almost 2 billion people rely on Asia's Hindu Kush Himalayan glaciers for agriculture, industry and drinking water.

The significance of these glaciers cannot be overstated. They serve as natural water towers, storing precipitation as ice and snow during colder months and releasing it gradually during warmer periods. This natural regulation system has sustained civilizations for millennia, supporting some of the most densely populated regions on the planet. With over 900 million inhabitants, the South Asian river basins of the Indus, Ganges and Brahmaputra are amongst the world's most densely populated areas.

The Vital Role of Himalayan Glaciers in Regional Water Systems

Natural Water Reservoirs and River Systems

The glaciers of the Himalayas function as massive natural reservoirs, accumulating snow and ice over time and releasing meltwater in a carefully balanced cycle. The glaciers in this region are the headwaters of several of Asia's great river systems, including the Ganges-Brahmaputra, Indus, Mekong, Yangtze, and Yellow rivers. These river systems form the lifeblood of South Asia, providing essential resources that support billions of people across multiple nations.

During the warmer months, particularly in late spring and summer, glacial melt contributes significantly to river flow. Water supply in these areas depends on melting glaciers and snow from the Himalaya, and meltwater is used for crop irrigation and provides farmers with sufficient water in periods of drought and minimal rainfall. This seasonal pattern is particularly crucial during dry periods when rainfall is minimal and agricultural demands are high.

These rivers are the sources of drinking water and irrigation supplies for billions of people. The water flowing from these glaciers doesn't just quench thirst or irrigate crops—it powers entire economies. These rivers also generate hydropower and support important ecological values, such as fisheries.

Supporting Agriculture and Food Security

Agriculture across South Asia depends heavily on the reliable water supply from Himalayan glaciers. Recent research has quantified this dependence with striking precision. The faster melting of glaciers in the Himalayas in recent years will affect the crop production and livelihoods of around 129 million farmers who depend on meltwater from these glaciers.

The relationship between glacier meltwater and agricultural production is complex and varies by crop type and season. Research shows for the first time to what extent irrigation systems are fed with meltwater, how meltwater contributes to crop production, in which period it is most crucial and for which crop, finding that mainly the production of rice and cotton strongly depends on the timely availability of snow and glacier melt water.

The irrigation infrastructure in the region has evolved over centuries to maximize the use of glacier-fed rivers. The Indus and Ganges basins have complex irrigation systems consisting of canals to transport water to the agricultural fields, sometimes over hundreds of kilometers. These sophisticated networks distribute meltwater across vast agricultural landscapes, enabling food production that sustains hundreds of millions of people.

Food security concerns are already pressing in the region. More than 30% of the people living in the countries bordering the Himalayas do not have access to enough food and 50% experience malnutrition. Any disruption to water supplies threatens to exacerbate these already dire conditions.

Hydropower Generation and Energy Security

Mountains are the water towers of the world and in many regions, the volume and timing of streamflow from glacial and snowmelt are critical for agricultural production, hydropower generation, water supply, and the functioning and health of ecosystems. The consistent flow of glacier-fed rivers makes them ideal for hydropower development, providing renewable energy to rapidly developing economies.

In the Hindu Kush-Himalayan region in particular, the large populations of China and South Asia rely on both the water and electricity generation provided by the major rivers. Hydropower facilities throughout the region depend on predictable water flows, which are increasingly threatened by changing glacier dynamics.

Changes in glacier melt patterns pose significant risks to the expanding hydropower sector. Changes in Himalayan glacier melt threaten the safe and expanding hydropower industry throughout the region. As glaciers shrink and melt patterns become more erratic, the reliability of hydropower generation comes into question, potentially affecting energy security for millions of people.

The Accelerating Crisis: Climate Change and Glacier Retreat

Unprecedented Rates of Glacier Melting

The scientific evidence regarding Himalayan glacier retreat is both comprehensive and alarming. Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating. However, the rate of this retreat has accelerated dramatically in recent decades, reaching levels unprecedented in human history.

Ice is now being lost from Himalayan glaciers at a rate that is at least ten times higher than the average rate over past centuries. This acceleration represents a fundamental shift in glacier dynamics. Over recent decades the Himalayan glaciers have lost ice ten times more quickly over the last few decades than on average since the last major glacier expansion 400-700 years ago, a period known as the Little Ice Age.

The acceleration has become even more pronounced in recent years. The Himalayan glaciers lost ice at a rate 65% faster between 2010 and 2019 than over the previous decade (2001-2010). This rapid acceleration has caught even scientists by surprise, with new data revealing conditions worse than previously expected.

Himalayan glaciers are shrinking far more rapidly than glaciers in other parts of the world -- a rate of loss the researchers describe as "exceptional". This exceptional rate of loss distinguishes the Himalayan region from other glaciated areas around the world, highlighting the particular vulnerability of these glaciers to climate change.

The Himalayan region is experiencing warming at rates significantly higher than the global average. The Himalayas are heating up at rates up to 0.7°C higher than the global average. This enhanced warming in mountain regions is a well-documented phenomenon, but the rate observed in the Himalayas is particularly concerning.

The HKH has warmed by +0.28°C on average per decade since the 1950s, rendering it highly vulnerable to rapid ice loss, with irreversible changes occurring to downstream water supplies as temperatures rise. This sustained warming trend has fundamentally altered the region's climate, pushing glacier systems beyond their capacity to maintain equilibrium.

This acceleration in the rate of loss has only emerged within the last few decades, and coincides with human-induced climate change. The timing of this acceleration provides clear evidence of the anthropogenic influence on glacier dynamics, linking local environmental changes to global greenhouse gas emissions.

Projections for Future Ice Loss

The future of Himalayan glaciers depends critically on global efforts to limit temperature rise. Scientists have developed multiple scenarios based on different warming trajectories, and all of them paint a concerning picture. Climate change means they are rapidly melting and could lose up to three-quarters of their volume by the end of our century.

Even under the most optimistic scenarios, significant ice loss is inevitable. A third of the ice stored in Asia's glaciers will be lost by the end of the century even if global warming stays below 1.5 degrees Celsius. This represents the best-case scenario, assuming aggressive global action to limit emissions.

At 1.5 degrees Celsius or 2 degrees Celsius of warming above preindustrial temperatures, glaciers across the entire region will lose 30 percent to 50 percent of their volume by 2100. However, current emission trajectories suggest the world is heading toward higher levels of warming.

At 3 degrees Celsius of warming – what the world is roughly on track for under current climate policies – glaciers in the Eastern Himalayas, which includes Nepal and Bhutan, will lose up to 75 percent of their ice. Under even more extreme warming scenarios, the losses become catastrophic. At 4 degrees Celsius of warming, that increases to 80 percent.

Recent assessments have revealed that the situation may be even more dire than previously thought. Glaciers in Asia's Hindu Kush Himalayas are melting at unprecedented rates and could lose up to 75 percent of their volume by century's end, scientists have said, warning of dangerous flooding and water shortages for the nearly 2 billion people who live downstream.

Cascading Impacts on Water Availability and Regional Security

The Paradox of Increased Flow Followed by Scarcity

The threat from this climate-induced melting is double-edged: as the glaciers' water storage continues to shrink, it will cause increased flooding and erosion during melting periods – and water scarcity during dry seasons. This paradoxical situation presents complex challenges for water resource management.

In the short term, accelerated glacier melt actually increases water availability in glacier-fed rivers. However, this temporary abundance masks a looming crisis. As glaciers continue to shrink, their capacity to store water and regulate seasonal flows diminishes. Eventually, the increased melt gives way to reduced flows as the ice reserves are depleted.

Two billion people living within these mountains and downstream river valleys depend on melting ice and snow for freshwater resources, and the availability of this water is expected to peak mid-century and then decline as rising temperatures shrink both glaciers and snowpack. This mid-century peak represents a critical turning point, after which water scarcity will become increasingly severe.

In the short term, these rivers are expected to flood more frequently, which could destroy neighboring homes and farmland, but as the glaciers shed more of their ice, the rivers are eventually expected to run dry, adding strain to agricultural activity throughout the region.

Implications for Water Security

Many basins in the HKH region are "water stressed", and this stress is projected to increase due to large forecasted population growth. The combination of declining water availability and increasing demand creates a perfect storm for water security challenges.

However, the relationship between glacier retreat and water availability is more complex than simple cause and effect. At lower elevations, glacial retreat is unlikely to cause significant changes in water availability over the next several decades, but other factors, including groundwater depletion and increasing human water use, could have a greater impact.

Higher elevation areas could experience altered water flow in some river basins if current rates of glacial retreat continue, but shifts in the location, intensity, and variability of rain and snow due to climate change will likely have a greater impact on regional water supplies. This highlights the importance of considering glacier melt within the broader context of climate change impacts on the hydrological cycle.

Social changes, such as changing patterns of water use and water management decisions, are likely to have at least as much of an impact on water demand as environmental factors do on water supply. This underscores the need for integrated approaches that address both supply-side and demand-side factors.

Threats to Agriculture and Food Production

Without a reliable source of water, crop yields are expected to decline, potentially threatening food security in multiple countries. The agricultural implications of glacier retreat extend far beyond simple water availability, affecting crop selection, planting schedules, and farming practices that have been refined over generations.

Millions of people are in danger of losing their livelihoods and their sources of food due to the fast melting of the Himalayan glaciers. The scale of this threat is staggering, potentially affecting the food security and economic stability of entire nations.

The impacts are already being felt by communities dependent on glacier-fed water systems. In Nepal, a hotter climate and changing rainfall patterns are already impacting mountain livelihoods, with low-income communities and those whose livelihoods depend on tourism and traditional farming already seeing their way of life changing.

Specific examples illustrate the human dimension of these changes. Traditional livelihoods such as yak herding are becoming increasingly difficult as pastures dry up and water sources diminish. Communities that have lived in harmony with their environment for centuries are being forced to adapt or relocate, representing a profound disruption to cultural and economic systems.

Geopolitical Implications and Regional Stability

The water resources of the Himalayan region have significant geopolitical dimensions. The surface water of these rivers and associated groundwater constitute a significant strategic resource for all of Asia. As water becomes scarcer, the potential for conflict over shared water resources increases.

These changes are expected to lead to an increase in regional migration and climate refugee levels in ways that could exacerbate geopolitical tensions. The movement of populations displaced by water scarcity and agricultural failure could strain international relations and overwhelm the capacity of receiving regions.

More than 90% of Afghanistan's agriculture depends on groundwater sources created by the Himalayan glaciers, and if these sources dry up in the decades ahead, millions of people could be left without a source of food or income, driving people to find relief across the border in Pakistan. This example illustrates how glacier retreat in one region can create cascading effects across international borders.

A glaciologist at the British Antarctic Survey highlighted the glaciers' crucial role in providing water and food security for the region's communities, stating that taking the ice away exposes people to serious water stress and the consequences are local, regional and potentially global, in terms of conflict and migration.

Emerging Hazards: GLOFs and Natural Disasters

Understanding Glacial Lake Outburst Floods

As glaciers retreat, they often leave behind depressions that fill with meltwater, forming glacial lakes. While these lakes can serve as temporary water storage, they also pose significant hazards. Himalayan glaciers are declining faster where they end in lakes, which have several warming effects, and the number and size of these lakes are increasing so continued acceleration in mass loss can be expected.

Melting glaciers also increase the risk of hazards such as glacial lake outburst floods (GLOFs) and landslides, both of which are projected to increase over coming decades. GLOFs occur when the natural dams holding back glacial lakes fail, releasing massive volumes of water in catastrophic floods.

Glacial melt due to increasingly unpredictable climate and disrupting weather patterns is a key contributor to some of Asia's flooding events. These events can occur with little warning, devastating downstream communities and infrastructure.

Recent disasters have demonstrated the deadly potential of GLOFs. In northern India's Uttarakhand state, a glacial disaster in 2021 saw water trapped within a glacier burst, causing an avalanche that swept away houses, bridges and roads and left dozens dead. Such events are becoming more frequent as climate change destabilizes glacier systems.

Increased Frequency of Natural Disasters

Deadly floods and avalanches in the Himalayan region have already increased over the past decade or so, and scientists have linked the greater frequency and intensity of the disasters to climate change and global warming. The pattern is clear: as glaciers become more unstable, the communities living in their shadow face increasing danger.

Climate-driven erratic weather and warming in the region is contributing towards more snow melt, thereby destabilising glaciers, and due to this, the threat of dangerous floods and glacial disasters looms large in the region, risking the way of life for many millions of people.

A recent example from Pakistan illustrates the destructive power of glacier-related disasters. Record temperatures in March and April hastened melting of the Shisper Glacier, creating a lake that swelled and burst through an ice dam, with a torrent of water and debris flooding the valley below, damaging fields and houses, wrecking two power plants, and washing away parts of the main highway and a bridge.

Infrastructure Vulnerability

This risks disrupting water supplies for agriculture, drinking and energy generation, as well as damaging infrastructure. The infrastructure built to harness and distribute water from glacier-fed rivers was designed based on historical flow patterns that are rapidly becoming obsolete.

Roads, bridges, hydropower facilities, and irrigation systems all face increased risks from both flooding during periods of rapid melt and reduced water availability during dry seasons. The economic costs of adapting or replacing this infrastructure are substantial, particularly for developing nations with limited resources.

Monitoring and Understanding Glacier Dynamics

Advances in Glacier Monitoring Technology

Understanding the complex dynamics of Himalayan glaciers requires sophisticated monitoring systems. Scientists now have data on almost every glacier in high mountain Asia and know how these glaciers have changed not only in area but in mass during the last 20 years. This represents a remarkable achievement in scientific observation and data collection.

Satellite technology has revolutionized glacier monitoring, enabling scientists to track changes across vast and often inaccessible terrain. The team used satellite images and digital elevation models to produce outlines of the glaciers' extent 400-700 years ago and to 'reconstruct' the ice surface. These techniques allow researchers to place current changes in historical context, revealing the unprecedented nature of recent glacier retreat.

Recent satellite data has revealed concerning trends. Glacier-covered areas in the Himalayas have decreased by over 30% in the last four decades. This dramatic reduction in glacier extent represents a fundamental transformation of the region's landscape and hydrology.

Complex Factors Affecting Glacier Behavior

Glacier dynamics in the Himalayas are influenced by multiple factors beyond simple temperature changes. Glaciers which have significant amounts of natural debris upon their surfaces are also losing mass more quickly: they contributed around 46.5% of total volume loss despite making up only around 7.5% of the total number of glaciers.

Current understanding of glacier dynamics includes mass loss trends, basin-wise variability, debris-covered glacier processes, and the role of black carbon. Black carbon, deposited on glacier surfaces from air pollution and biomass burning, reduces surface reflectivity and accelerates melting.

While we must act urgently to reduce and mitigate the impact of human-made climate change on the glaciers and meltwater-fed rivers, the modelling of that impact on glaciers must also take account of the role of factors such as lakes and debris. This complexity means that accurate predictions require sophisticated models that incorporate multiple variables.

Research Gaps and Future Needs

Despite the advances in knowledge about Himalayan glaciers, scientists say many research gaps remain. Continued investment in monitoring and research is essential for improving predictions and developing effective adaptation strategies.

The study identifies limitations in long-term glacier monitoring, glacio-hydrological modelling, and socioeconomic vulnerability assessments. Addressing these gaps requires sustained funding, international cooperation, and integration of multiple scientific disciplines.

Conservation Strategies and Climate Action

The Imperative of Emissions Reduction

The most fundamental requirement for protecting Himalayan glaciers is rapid and substantial reduction in global greenhouse gas emissions. To prevent additional ice loss, greenhouse gas emissions must be reduced through the use of clean and renewable energy sources, and we need to reduce our greenhouse gas emissions as quickly as we can.

Limiting warming to around 1.5 degrees Celsius requires global greenhouse gas emissions to peak before 2025, and be reduced by 43% by 2030, but the world is not currently on course to keep those targets within reach. The gap between what is needed and current trajectories represents a critical challenge for global climate policy.

Should the world manage to meet the weaker Paris climate target of just under two percent warming, glacier shrinkage would be "only" at a maximum of 50 percent, and should it get on a carbon-neutral path, ICIMOD researchers believe it is likely that glaciers would not melt further. This offers a glimmer of hope, suggesting that aggressive climate action could stabilize glacier systems.

Adaptation and Water Management

While emissions reduction is essential, communities and nations must also adapt to changes already underway. Rainwater harvesting, improving man-made reservoirs or increasing groundwater use where possible might offset some of the loss or shift in meltwater, but these strategies are not sufficient.

Urgent policy action is needed to enhance adaption measures, support those already affected by cryosphere loss; and not least, mitigate global emissions to uphold 1.5°C as a guardrail for the billions reliant on the HKH region. This requires coordinated action at multiple levels, from local communities to international organizations.

Effective adaptation requires understanding and addressing social dimensions of water use. Governments will need to think about food security strategies for dependent communities and further studies looking at the changing supplies of water as a resource in South Asia must take into account socio-economic developments alongside those affected by climate change.

International Cooperation and Policy Frameworks

With an issue of this scale there is a clear need for political cooperation to ensure that these people are not pushed into poverty by global warming. The transboundary nature of Himalayan water resources necessitates cooperation among nations that share these river systems.

Recent high-level attention to the crisis demonstrates growing recognition of its importance. The United Nations Secretary-General warned that Himalayan glaciers are "caving in," urging immediate action to address the climate crisis, especially in the world's most fragile ecosystems, in a video message to the inaugural Sagarmatha Sambaad, or "Everest Dialogue," convened by the Government of Nepal.

Record temperatures have meant record glacier melt, with Nepal losing close to one-third of its ice in just over thirty years, and glaciers melting 65 per cent faster in the last decade than in the one before. This stark assessment from the UN's highest office underscores the urgency of the situation.

Financial Support and Climate Justice

Achieving climate goals demands investing in renewable energy, fulfilling the $1.3 trillion climate finance goal agreed at COP29, doubling adaptation finance to at least $40 billion this year as pledged by developed countries, and providing robust, sustained support to the Loss and Damage Fund. Financial resources are essential for both mitigation and adaptation efforts.

The issue of climate justice is particularly acute in the Himalayan region. The people living in these mountains who have contributed next to nothing to global warming are at high risk due to climate change. Communities that have the smallest carbon footprints are bearing disproportionate impacts from climate change driven by emissions from industrialized nations.

For communities in Nepal, climate change is something that was imposed on them by the rest of the world, and the future of these life-giving glaciers "are subject to decisions made across the world, to patterns of consumption and pollution that Nepali people have little or no control over". This reality demands that the international community take responsibility for supporting adaptation and building resilience in affected regions.

Human Stories: Communities on the Front Lines

Impacts on Traditional Livelihoods

Behind the statistics and scientific projections are real people whose lives are being transformed by glacier retreat. Traditional livelihoods that have sustained communities for generations are becoming increasingly difficult or impossible to maintain.

The story of yak herders in Nepal illustrates these challenges. Warming temperatures have reduced the availability of water and fresh grass for livestock, forcing herders to drastically reduce their herds or abandon the practice entirely. As the lack of fresh water and livestock feed becomes more acute, people will have no choice but to move to lower altitudes to continue their lives.

People in the region are already seeing changes that are beyond anything witnessed for centuries. This represents not just an economic challenge but a cultural crisis, as traditional knowledge and practices become less relevant in a rapidly changing environment.

Vulnerability of Marginalized Communities

Water scarcity will likely affect the rural and urban poor most severely, as these groups have the least capacity to move to new locations as needed. Socioeconomic factors determine who has the resources to adapt and who will be left behind.

It is predicted that the region will become increasingly urbanized as cities expand to absorb migrants in search of economic opportunities, and as living standards and populations rise, water use will likely increase-for example, as more people have diets rich in meat, more water will be needed for agricultural use. This creates a vicious cycle where climate-driven migration increases pressure on already stressed water resources.

The Need for Community-Centered Solutions

Government officials and experts also need to ask communities what they need and take their answers seriously. Effective adaptation strategies must be developed in partnership with affected communities, incorporating local knowledge and respecting community priorities.

Young people in the region are increasingly vocal about demanding action. Over 100 children and young people demanded urgent and inclusive climate action that recognizes them as rights-holders and climate actors – not just passive victims. This represents a shift toward more inclusive and participatory approaches to climate adaptation.

Looking Forward: Pathways to Resilience

Integrated Water Resource Management

Addressing the challenges posed by glacier retreat requires comprehensive approaches to water resource management. This includes improving water use efficiency, developing alternative water sources, and creating more resilient agricultural systems. Modern irrigation technologies and management practices can help reduce water waste and increase productivity.

Groundwater management will become increasingly important as surface water becomes less reliable. However, this must be done sustainably to avoid depleting aquifers. Rainwater harvesting and water storage infrastructure can help buffer against seasonal variability in water availability.

Early Warning Systems and Disaster Preparedness

Given the increasing frequency of GLOFs and other glacier-related hazards, developing robust early warning systems is critical. This requires continued investment in monitoring technology, communication infrastructure, and community preparedness programs. Communities at risk need clear evacuation plans and the resources to implement them quickly when warnings are issued.

Infrastructure in vulnerable areas must be designed or retrofitted to withstand increased flooding risks. This includes strengthening dams, improving drainage systems, and relocating critical facilities away from high-risk zones where feasible.

Building Regional Cooperation

The transboundary nature of Himalayan water resources makes regional cooperation essential. Mechanisms for sharing data, coordinating water management, and resolving disputes peacefully must be strengthened. Climate change adds urgency to longstanding challenges of water allocation among nations sharing river basins.

International platforms like the Sagarmatha Sambaad provide opportunities for dialogue and coordination. These forums can facilitate knowledge sharing, coordinate research efforts, and build political will for collective action. The challenges facing the Himalayan region require solutions that transcend national boundaries.

The Role of Science and Innovation

Continued scientific research is essential for understanding glacier dynamics and improving predictions of future changes. We know much more about the processes which govern glacial melt, and this information will give policymakers some instruments to really plan for the future. Translating scientific knowledge into actionable policy requires effective communication between researchers and decision-makers.

Innovation in water management technologies, agricultural practices, and renewable energy systems can help communities adapt to changing conditions. Investment in research and development should focus on solutions appropriate for the specific contexts of Himalayan communities, considering both technical feasibility and social acceptability.

Conclusion: A Call to Action

The Himalayan glaciers stand at a critical juncture. The Himalayan glaciers, a vital component of the Earth's cryosphere, are retreating at an unprecedented rate due to intensifying climate change, with far-reaching consequences for regional hydrology, ecosystems, and societies. The scale and speed of these changes demand immediate and sustained action at all levels.

The acceleration of melting of Himalayan glaciers has significant implications for hundreds of millions of people who depend on Asia's major river systems for food and energy. This is not a distant future threat—communities are already experiencing the impacts, and the window for preventing the most catastrophic outcomes is rapidly closing.

Changes to the glaciers, snow and permafrost of the region driven by global warming are "unprecedented and largely irreversible". While some changes are now inevitable, the severity of future impacts depends on actions taken today. Every fraction of a degree of warming avoided translates to less ice lost and fewer people displaced.

The challenge of protecting Himalayan glaciers and the communities that depend on them requires action on multiple fronts: aggressive emissions reductions to limit future warming, substantial financial support for adaptation in vulnerable regions, improved monitoring and early warning systems, sustainable water resource management, and strengthened regional cooperation. No single intervention is sufficient; comprehensive approaches addressing both causes and consequences of glacier retreat are essential.

Achieving these goals demands bold collaboration. The fate of Himalayan glaciers will be determined by decisions made in capitals around the world, from emission reduction commitments to climate finance allocations. The international community has both a moral obligation and a practical interest in supporting the resilience of Himalayan communities and ecosystems.

The impacts of the rapid glacial melt in the Himalayas will be felt around the world. What happens in the mountains of South Asia has implications for global food security, geopolitical stability, and the broader climate system. The Himalayan glaciers are not just a regional concern—they are a global priority.

The science is clear, the impacts are accelerating, and the need for action is urgent. Protecting the Himalayan glaciers and the billions of people who depend on them requires treating this crisis with the seriousness it deserves. The time for incremental measures has passed; transformative change is needed now. The glaciers are melting, but the future is not yet written. With determined action, it is still possible to build resilience, protect vulnerable communities, and preserve these vital water towers for future generations.
