India made air pollution on Himalayas makes life threat in water supply.

In 2025, Chinese Academy of Sciences, Tsinghua University China, and Utah State University US jointly made study found that South Asian black carbon aerosols accelerate the loss of solid water reserves on the Himalayas; which threats the water supply for the Indus and Ganges-Brahmaputra river basins.

The study published on the Communications Earth & Environment in June 4, 2025; in titled Reduced solid water storage over the Tibetan Plateau caused by black carbon.

In this comprehensive study, we first systematically assesses the BC direct melting and indirect precipitation mass gain effects on glaciers for the 2007-2016 period, and scrutinized its potential influences on the water resources and demand. We observed that BC originating in South Asia has resulted in a greater decrease in ice mass over the southern aspects of the TP, especially in the Himalayas (33.7%).

The key takeaway is the discovery of a modification of the atmospheric dynamics in the Indian subcontinent that has altered the precipitation regime in the region. This adds another component to the already established understanding that atmospheric warming and associated changes in energy fluxes are the dominant factors affecting the intensive glacier shrinkage over the Himalayas.

Himalayan glaciers provide meltwater to densely populated catchments in South Asia such as the Indus and Ganges–Brahmaputra basins. Glacial mass decline due to South Asian BC can affect downstream water demand in these two endorheic basins.

Therefore, there was a negative feedback between South Asian human emissions and the TP cryosphere advocates for BC mitigation to ensure future water resource stability and societal well-being. The specific actionable strategies for reducing BC emissions such as promoting cleaner energy technologies, improving fuel quality, and implementing stricter emission standard, will contribute to the potential socioeconomic benefits of BC emission reduction, including improved public health outcomes, enhanced agricultural productivity, and climate co-benefits.
