According to a UNESCO evaluation released on Friday, glaciers are facing the fastest melt in history, with the past three years experiencing the greatest mass loss ever recorded. The rate of glacier disappearance is alarming. According to Michael Zemp, head of the World Glacier Monitoring Service, since 1975, glaciers have lost about 9,000 gigatons of ice, equivalent to a block of ice roughly the size of Germany and 25 meters thick.

According to the report, glaciers have lost 450 gigatons of ice in 2024 alone, setting records in five of the previous six years. Climate change, brought on by emissions from fossil fuels, is predicted to increase these losses, which span the Tibetan Plateau, South America, the Alps, and the Arctic. As sea levels rise and freshwater supplies decline, rising global temperatures threaten escalating economic, environmental, and social disasters.

Presenting the findings at a UNESCO conference in Paris on the first World Day for Glaciers, the organization urged immediate international action to protect these vital glacier masses.

Rising Threats to Communities and Water Security

One of the main causes of sea level rise is the rapid melting of mountain glaciers, which raises the possibility of catastrophic floods and disrupts water supplies essential to agriculture and hydroelectric power for billions of people. About 275,000 glaciers remain worldwide, according to Stefan Uhlenbrook, director of water and cryosphere at the World Meteorological Organization (WMO). Together with the Greenland and Antarctic ice sheets, they provide around 70% of the world’s freshwater.

Uhlenbrook emphasized how critical it is to enhance scientific forecasting, monitoring, and early warning systems to reduce the threats brought on by glacier retreat. Rising temperatures are predicted to exacerbate natural hazards like glacial lake outburst floods (GLOFs), flash floods, avalanches, landslides, and droughts in areas that rely on snowfall for water. A farmer in Peru who lives downstream of a melting glacier has filed a lawsuit against RWE, a German energy firm, requesting that it pay for flood protection measures in proportion to its past carbon emissions.

Cultural and Social Consequences of Glacial Disappearance

Glacial melt impacts spiritual and cultural customs and environmental issues. Glaciologist Heidi Sevestre of the Arctic Monitoring and Assessment Program believes that the Rwenzori Mountains in Uganda and the Democratic Republic of the Congo will no longer have glaciers by 2030. Some Indigenous Bakonzo people consider these glaciers home to a deity called Kitasamba, making their extinction deeply significant.

Sevestre said it was “heartbreaking” to see the changes in the field and cautioned that some areas are losing their glaciers far more quickly than expected. Local disputes over water have already intensified in East Africa as a result of glacier melting.

Global glacier melt has a significant cumulative impact. As glaciers are facing the fastest melt in history, their disappearance has caused an 18-millimetre rise in global sea levels between 2000 and 2023, averaging about 1 millimetre per year. According to the World Glacier Monitoring Service, up to 300,000 people could be at risk of flooding yearly for every millimetre of sea level rise.

Sevestre emphasized that “billions of people are connected to glaciers, whether they know it or not” and called for international cooperation to save them.
