Global glacier melting and Arctic warming accelerate

Global warming continues to drive significant changes in ice masses and marine environments. Greenland and Antarctica have lost over 11 trillion tons of ice, primarily due to glaciers sliding into the ocean, contributing to rising sea levels and threatening coastal and mountainous communities.

In the Himalayas, melting glaciers have led to catastrophic events. On August 26, an avalanche of ice, water, and rock on Lantang Lirung, near the Nepal-China border, resulted in approximately 1,500 deaths and thousands of missing persons. Scientists from the World Weather Attribution initiative attributed the collapse to geological and climatic factors, noting that global warming is destabilizing mountain slopes.

Similar crises are emerging in Europe, including the Monte Perdido glacier in the Pyrenees and melting in the Alps. In 2025, the Swiss village of Blatten was evacuated due to the threat of ice and rock avalanches.

The Arctic is warming at twice the global average through a process known as Arctic amplification. As sea ice melts, the Earth’s albedo effect decreases; instead of reflecting sunlight, the darker ocean absorbs more heat. This loss of reflective ice is estimated to be responsible for 30% to 50% of global warming, creating a dangerous feedback loop.
