Melting glaciers and the loss of seasonal snow pose significant risks to the stability of water resources in South Asia. The 55,000 glaciers in the Himalaya, Karakoram, and Hindu Kush (HKHK) mountain ranges store more freshwater than any region outside of the North and South Poles. Their ice reserves feed into three major river basins in South Asia—the Indus, Ganges, and Brahmaputra—that are home to 750 million people. One major regional driver of the accelerating glacier melt is climate change, which is altering the patterns of temperature and precipitation. A second driver may be deposits of anthropogenic black carbon (BC), which increase the glaciers’ absorption of solar radiation and raise air temperatures. BC is generated by human activity both inside and outside of South Asia, and policy actions taken by the South Asian countries themselves may meaningfully reduce it. Glaciers of the Himalayas: Climate Change, Black Carbon, and Regional Resilience investigates the extent to which the BC reduction policies of South Asian countries may affect glacier formation and melt within the context of a changing global climate. It assesses the relative impact of each source of black carbon on snow and glacier dynamics. The authors simulate how BC emissions interact with projected climate scenarios. They also estimate the extent to which these glacial processes affect water resources in downstream areas of these river basins and present scenarios until 2040. Their policy recommendations include the following: Full implementation of current BC emissions policies can significantly reduce BC deposition in the region; additional reductions can be realized by enacting and implementing new policies that are economically and technically feasible. Improving the efficiency of brick kilns could be key to managing BC, and modest up-front investments could pay off quickly. Cleaner cookstoves and cleaner fuels can help to reduce BC and improve local air quality. Improving institutions for basin-based water management and using price signals are essential elements of more efficient water management. Careful management of hydropower and storage resources will require developers to factor in changing water flows and consider planning for large storage projects to stabilize water availability. Regional cooperation and the exchange of information can be an effective transboundary solution, helping countries to manage glaciers and related natural assets collaboratively. New policies are needed to reverse trends like the melting of glaciers. Success will require an active, agile cooperation between researchers and policy makers. To support an open dialogue, the model developed and used in this book is an open-source, state-of-the-art model that is available for others to use and improve on.

Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. 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. Recent studies show that 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. Himalayan Glaciers: Climate Change, Water Resources, and Water Security makes recommendations and sets guidelines for the future of climate change and water security in the Himalayan Region. This report emphasizes that 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. 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. It is predicted that the region will become increasingly urbanized as cities expand to absorb migrants in search of economic opportunities. 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. The effects of future climate change could further exacerbate water stress. Himalayan Glaciers: Climate Change, Water Resources, and Water Security explains that changes in the availability of water resources could play an increasing role in political tensions, especially if existing water management institutions do not better account for the social, economic, and ecological complexities of the region. To effectively respond to the effects of climate change, water management systems will need to take into account the social, economic, and ecological complexities of the region. This means it will be important to expand research and monitoring programs to gather more detailed, consistent, and accurate data on demographics, water supply, demand, and scarcity.

This book is about the Himalayan ranges as a source of fresh water supply and a perennial store house of ice, snow and permafrost as well as a vast repository of rich biodiversity, in the light of climate change. Special attention is given to the dynamics of snow and glaciers in the northwestern Himalayas, assessment of climate change patterns, and the consequences of changes and flow regime in order to understand the behaviour of climate change in the northwestern Himalayas. The outcome of melting glaciers are pro-glacial lakes. Their increasing size and potential danger of outbursts requires systematic study, particularly where there is the risk of impact on life and property. Furthermore, the changing trend of the hydrological cycle on a regional or local scale is another area of research which calls for the attention of geoscientists. To date there is a scarcity of reliable data meaning that a concerted effort is still required by all parties.

We hear about pieces of ice the size of continents breaking off of Antarctica, rapidly melting glaciers in the Himalayas, and ice sheets in the Arctic crumbling to the sea, but does it really matter? Will melting glaciers change our lives? Absolutely.The ice ages and the interglacial periods like we live in now are built and destroyed by glaciers. Glaciers hold three quarters of our freshwater, yet we don't have laws to protection them from climate change. Melting glaciers raise the seas, alter global ecosystems, warm our climate and bring onfloods that swamp millions of acres of land destroying coastal ecosystems and leaving hundreds of millions homeless. Healthy glaciers help keep our planet cool by reflecting solar heat away from the Earth and provide critical freshwater supply to billions that live within their meltwater runoffbasins. But melting glaciers alter ocean temperature, warm the atmosphere and cause havoc to the ocean currents and to the global jet stream, causing inclement weather, prolonged and recurrent droughts, heavy rains and intense, frequent and unpredictable storms. As glaciers melt away, their criticalenvironmental functions and services will wither. And as climate change warms their core, their weakening internal structure will cause a growing number of glacier tsunamis that can send deadly massive ice blocks, rocks, earth and billions of liters of water rushing down mountain valleys that takeout anything in their path. It has happened before in the Himalayas, in the Central Andes, in the Rockies and Western Cascades, and in the European Alps and it will happen again. As glaciers melt so do the vast swaths of permafrost environments that thrive in their surroundings, where thawingmillenary terrain rich in ice but also in methane gas captured hundreds of thousands of years ago, is now released into the atmosphere intensifying climate change even further.In his new book Meltdown, Jorge Daniel Taillant takes readers deeper into the cryosphere and connects the dots between climate change, glacier melt and the impacts that receding glacier ice brings to livability on Earth, to our environments and to our neighborhoods. He walks us through thelittle-known realm of the periglacial environment, a world where invisible subsurface rock glaciers with solid ice cores that will outlive exposed glaciers in our warming climate, but will they suffice to maintain our cryosphere and climate ecology in balance? In two closing chapters Taillant looksat actions that can help stop climate change and save glaciers and also contrasts how society, politics and our leaders have responded to address the COVID-19 pandemic and yet largely failed to address the even larger looming and escalating crisis of climate change.Meltdown is about glaciers and their unfolding demise during one of the most critical moments of our climate crisis. We may still be in time to save the cryosphere, if we can reconsider glaciers in a whole new light and understand the critical role they play in our own sustainability and if we canawaken to see how through glacier melt, geological ages are changing right before our eyes.
