Glaciers are undergoing rapid and significant changes in global warming. Glacier shrinkage has a significant impact on global sea levels, regional water cycles, ecosystems and natural hazards.
Many studies have looked at changes in glaciers and the mechanisms that lead to such changes. However, few studies have focused on mitigating glacier ablation.
Recently, a research team from the Northwestern Institute of Environmental and Resources of the Chinese Academy of Sciences evaluated the effectiveness of the ice sheet to reduce melting of the Urumqi Glacier. 1, Tian Shan, China.
Their results are published in Remote monitoring.
By combining two high-resolution digital altitude models derived from ground-based laser scanning and unmanned aerial vehicles, albedo and meteorological dataresearchers quantify the ablation of glacier ablation under three different roofing materials.
The results show that covered areas can slow the melting of glaciers by approximately 29-56% compared to uncovered areas. The researchers also found that the nanofiber material showed a higher efficiency (56%) than the geotextile used in the experiment.
The method of artificially reducing the melting of glacial ice provides a scientific and practical basis for decision-making to mitigate and adapt to climate change.
