Mountain glacier preservation with artificial interventions: A review.

Area of Science:

• Glaciology
• Climate Science
• Environmental Engineering

Background:

• Mountain glaciers are critical freshwater sources threatened by anthropogenic warming.
• Accelerated glacier mass loss impacts ecosystems and human populations globally.
• Current conservation efforts focus on mitigating glacier retreat.

Purpose of the Study:

• To review and evaluate artificial methods for mitigating glacier mass loss.
• To assess the efficacy and trade-offs of snowmaking, water injection, compaction, and surface covering.
• To propose a framework for effective glacier conservation.

Main Methods:

• Synthesis of current artificial glacier intervention approaches.
• Evaluation of physical mechanisms, operational efficacy, and environmental impacts.
• Analysis of empirical data and case studies, including western China.

Main Results:

• Artificial snowmaking and water injection enhance accumulation.
• Manual compaction and surface covering limit ablation.
• Interventions provide local melt reduction but are insufficient for large-scale cryospheric decline.

Conclusions:

• Local technical strategies can be adaptively deployed in high-priority zones.
• Stringent global climate mitigation is crucial for long-term glacier preservation.
• A dual-pathway approach supports glacial functions and socio-ecological resilience.
