Which of the following glaciers in the Himalayas has started melting because of global warming?

Gangotri Glacier

The correct answer is option 2. Gangotri Glacier.

The Gangotri Glacier, located in the Indian state of Uttarakhand in the Himalayas, is one of the largest glaciers in the region. It is the source of the Ganges River, a sacred and culturally significant river in India. Like many glaciers around the world, the Gangotri Glacier has been affected by global warming, leading to melting and other environmental changes. Here's an explanation:

1. Global Warming Impact:

Global warming, primarily driven by the increase in greenhouse gas emissions, has resulted in rising temperatures worldwide.

Glaciers are sensitive indicators of climate change, and many have been experiencing a reduction in volume and surface area due to higher temperatures.

2. Gangotri Glacier Melting:

Observations and studies have documented the retreat and melting of the Gangotri Glacier over the years.

The higher temperatures cause the ice to melt at an accelerated rate during warmer seasons, contributing to the overall reduction of the glacier.

3. Consequences:

The melting of glaciers has several consequences, including the release of freshwater into downstream rivers and changes in the availability of water resources.

Glacial melt contributes to the flow of rivers and is a crucial water source for communities downstream.

4. Environmental Concerns:

The melting of glaciers has environmental implications, including impacts on ecosystems, biodiversity, and the stability of high-altitude regions.

The Gangotri Glacier's retreat is of particular concern due to its association with the Ganges River, upon which millions of people depend for water resources.

It's important to note that glacier melting is a complex process influenced by various factors, and while global warming is a significant driver, regional variations and other local factors can also play a role. Monitoring and understanding these changes are essential for assessing the potential impacts on water resources and ecosystems in the Himalayan region.
