Global glaciers melting at alarming rate, UN warns of rising seas

Glaciers across the globe are disappearing at an unprecedented pace, according to the latest assessment from the United Nations' weather agency. The World Meteorological Organisation (WMO) said the rate of ice loss in 2025 represents a stark acceleration in glacier retreat, with implications for sea levels and freshwater supplies in vulnerable regions.

The alarming melting rates are being driven by a sustained period of exceptionally high global temperatures that has continued into 2026. The WMO report indicates that above-average warming shows no signs of abating, with far-reaching consequences for climate systems worldwide. The rapid ice loss underscores the urgency of addressing climate change impacts on fragile ecosystems and coastal communities.

Rising sea levels pose particular risks for low-lying nations and island states across South and Southeast Asia, where millions of people live in coastal areas vulnerable to inundation. The combination of glacier melt and thermal expansion of warming oceans is contributing to sea level rise that threatens infrastructure, agriculture and settlements in the region.

The WMO findings add to mounting scientific evidence of accelerating climate impacts. Experts warn that without significant global action to reduce greenhouse gas emissions, glacier losses and sea level rise will continue to intensify, placing increasing pressure on governments and communities to adapt to a changing climate.
