Chinese scientists test fabric covering to slow glacier melting

A study on China's Dagu Glacier has shown promising initial results from an experimental technique using artificial fabric to slow the melting of ice reserves. During the first two months of the experiment, the fabric-covered section experienced a 27 percent reduction in ice melting compared to exposed areas, suggesting the approach can effectively protect glacial ice from solar radiation.

The protective fabric works by increasing the reflectivity of the glacier's surface, thereby reducing the amount of solar energy absorbed by the ice. This reflective property proved highly effective in the initial phase of the study, demonstrating that targeted interventions could preserve significant ice reserves over short periods.

However, researchers found that the fabric's protective qualities diminished as time progressed. The material's reflectivity decreased due to dust accumulation and weathering, eventually resulting in a more modest annual melting reduction of 15 percent. This decline in effectiveness suggests that maintaining such interventions would require regular maintenance and replacement.

Beyond the technical challenges, scientists identified substantial practical obstacles to scaling this solution. The logistics of covering large glacier areas with fabric, combined with ongoing maintenance requirements and associated costs, present significant hurdles to implementing this approach on a wider basis. Researchers concluded that while the technique merits further investigation, additional solutions will be necessary to address glacier loss in the region.
