GlobalHimalayan GlaciersThe Himalayan Mountains are home to the second largest mass of ice in the world, these glaciers are extremely important to the lives of many people, animals and ecosystems .The Himalayan range includes about 15,000 glaciers, which store about 12,000 km3 (3,000 cubic miles) of fresh water. The Himalayan Mountains are located in the northeastern part of India and pass through several countries including Pakistan, China, Afghanistan, Nepal and Bhutan. The glaciers of the Himalayan mountains are found at the sources of many major rivers essential in the Himalayan and Asian countries. Over the past 30 years, some glaciers in the Himalayas have retreated by a kilometer. The negative effects of CO2 and global warming on glaciers have caused them to melt or retreat, which has had many drastic effects. Over time, due to the retreat of glaciers, the normal melting of glaciers will no longer be able to contribute to the water supply of the Himalayan region each year. Water availability will not be affected at lower altitudes as it depends mainly on monsoon rains, but at higher altitudes the retreat of glaciers will cause changes in stream flow in some basins. The GLOF or Glacial Lake Outburst flood occurs when lakes, formed by melting glaciers, overflow. causing flooding. This is a very serious problem in the Himalayas because these lakes are near large rivers densely populated with villages and farms. The Tsho Rolpa glacial lake is located in the Dolakha district of Nepal and is one of the largest glacial lakes in the Himalayas. It has been classified by scientists as the most potentially dangerous glacial lake in the country. Tsho Rolpa is the result of the melting of several glaciers in the valleys above. If the middle of the Victoria University article says "a 70 meter chunk of ice broke off from the end face of the Tasman Glacier", releasing around seven million cubic meters of ice into Lake Tasman. The retreat of the Tasman Glacier will have a significant effect on tourism, which is a very important industry to New Zealand's people and economy. Currently, services are available for skiing on the Tasman Glacier, but in the future, due to the retreat of the glacier, these tourism opportunities will no longer be able to continue due to the dangers and possible disappearance of the glacier. Steepening ice slopes, increased risk of rockfall and increased debris cover are all challenges facing glacier sector tourism operators. Climate change will affect the survival of small towns in the region as most jobs are linked to tourism and tourism..
