Discover the new technique designed to reduce the melting of glaciers

The Chinese Academy of Sciences (CAS) brings together many scientists and engineers who aim to advancing science and technology. CAS is also interested in climatic changes and at the melting of the glaciers under the effect of global warming. The rapid shrinking of glaciers is one of its major concerns. Indeed, this phenomenon has a significant impact on the ocean levelthe water cycle and is the origin of many natural disasters.

It is true that many scientists around the world have already studied the ice melting mechanism to try to find the cause. However, no one has yet found the way to stop it. Fortunately, researchers from the Chinese Academy of Sciences seem to have found a way slow down the melting of glaciers.

This team based at the Northwest Institute of Eco-Environment and Resources has just published the results of their work in the scientific journal remote-sensing.

Protective materials to cover glaciers

We must remember that no glacier resembles another. Indeed, each of them has an accumulation zone, a transport zone and an ablation zone which give them a single signature. The study focused primarily on the ablation area ice-creams. Chinese researchers then came up with the idea of cover under three layers of materials different to slow down the melting.

This technique of artificial preservation of the cooler cover was tested on the Urumqi Glacier No. 1 covering the Tien Shan mountain range in China. They then compared melting ice on covered and uncovered areas using laser scans, aerial photos, weather records and thealbedo. To note that the albedo is a quantity that measures the temperature at the surface of the ice.

Covered ice melts slower

The measurements revealed that the ice melting on covered areas is about 29% to 56% inferiore to that of areas not covered by protective materials. The scientists also noticed that the nanofibers were more effective than geotextiles to slow the melting of the ice during the experiment.

These research work are of vital importance for the preservation of the environment. In fact, they provide a scientific and practical basis for decision-making on climate change mitigation and adaptation.
