Glaciers undergo rapid and significant changes under global warming. Glacier shrinkage has a significant impact on global sea levels, regional water cycles, ecosystems and natural hazards.

Many studies have considered glacier changes and the mechanisms that cause such changes. However, few studies have focused on reducing glacier ablation.

Recently, a research team from the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences evaluated the efficiency of glacier cover for melt reduction on Urumqi Glacier No. 1, Tien Shan, China.

Their results have been published in Remote Sensing

By combining two high-resolution digital elevation models derived from terrestrial laser scanning and unmanned aerial vehicles, albedo and meteorological data, the researchers quantified the reduction in glacier ablation under three different cover materials.

The results showed that material-covered areas could slow the melting of glaciers by about 29-56% compared to uncovered areas. The researchers also found that the nanofiber material showed a higher efficiency (56%) than the geotextiles used in the experiment.

The method of artificially reducing glacial ice melt provides a scientific and practical basis for decision-making about mitigating and adapting to climate change.
