On March 21, 2025, the world will mark the first-ever World Day for Glaciers, alongside the International Year of Glaciers’ Preservation (IYGP) 2025 and the Decade of Action for Cryospheric Sciences (2025-2034). This initiative by the UN General Assembly highlights the urgency of preserving our planet’s cryosphere. Glaciers worldwide are retreating at an alarming rate, with their melting waters often creating new glacial lakes or expanding existing ones. These changes significantly increase the risk of “Glacial Lake Outburst Floods”, so-called GLOFs. The danger of GLOFs are often unknown to local communities, but when unstable glacial lake dams collapse, the consequences can be catastrophic – destroying lives, livelihoods and infrastructure, with impacts reaching far downstream.
