The United Nations (UN) has officially declared 2025 as the “International Year of Glacier Conservation“. Additionally, they proclaimed March 21 of each year as World Glacier Day from now on.
The aim is to raise awareness about the fundamental role of glaciers, snow, and ice in the climate system and the hydrological cycle. Furthermore, to inform about the relevance this has in economies, socially, and environmentally.
Why This is the International Year of Glacier Conservation
The importance of glaciers.
In December 2022, the UN General Assembly adopted the resolution to declare this year as the International Year of Glacier Conservation, along with the proclamation of March 21.
It also aims to share the best practices and knowledge in this regard. Something essential to address issues related to rapid glacier melting and its consequences.
UNESCO and the World Meteorological Organization (WMO), in collaboration with governments and relevant organizations, are invited to facilitate the implementation of initiatives as lead agencies.
The coordination efforts are supported by an Advisory Council and four Working Groups representing over 75 international organizations and 35 countries.
The Working Groups drive the implementation of key activities planned for this year, ensuring that each initiative aligns with the overall objectives and has a global impact.
The Threat of Global Warming to Glaciers
According to scientists, global warming has led to the disappearance of thousands of glaciers worldwide since 2000. If the situation continues and greenhouse gas emissions are not drastically mitigated, at least half will have been lost by 2100.
Among those listed as “disappeared” are the Pizol Glacier in Switzerland (2019), the Sarenne Glacier in France (2023), the Anderson Glacier in United States (2015), and the Martial Sur Glacier in Argentina (2018).
Impact on Water Resources and Local Communities
The accelerated disappearance of glaciers not only affects the landscape but also has direct repercussions on communities that depend on meltwater for agriculture and drinking water supply.
During the warmer months, meltwater from glaciers has historically been a crucial resource in the Italian Alps.
The impact of melting for the planet.
However, in recent years, dangerous fluctuations in water supply have been recorded, with floods during periods of accelerated melting, followed by droughts during summer months when glaciers can no longer provide enough water.
The impact is also visible in surrounding ecosystems. As glaciers retreat, areas once covered by ice are being taken over by vegetation, altering the natural balance of flora and fauna in the region. For example, forests are advancing to higher altitudes, replacing the glacier landscapes that once dominated the region.
