UN: Glacier Melt Threatens Water and Global Climate Systems

The World Meteorological Organisation reports that the past three years have seen glaciers melt at record rates — areas worst affected include Svalbard, Norway, Sweden and the tropical Andes. 

Eastern Africa has already lost 80% of its glaciers, while South America’s Andes have seen glacier mass reduce by between one-third and one-half since 1998.

In regions like the Colorado River Basin in the United States, higher temperatures bring more rain and less snow, reducing the natural water storage that once slowly fed rivers. 

This shift affects downstream areas, including major agricultural zones, extending the crisis well beyond mountain regions.

Climate feedback loops and environmental risks

Glacial retreat contributes directly to climate change. 

As white ice vanishes, it reveals darker surfaces underneath that absorb more sunlight — intensifying global warming. 

This phenomenon is already visible in the Alps and Pyrenees, where glacier coverage has shrunk by around 40% since the late 1990s.

Thawing permafrost and melting ice are also destabilising mountain landscapes.
