The Deplete and Retreat team are delighted to be attending the first ever celebration for International Day of the Glacier in Paris, at the UNESCO HQ, in March 2025. We will be hosting a side event, entitled “A vanishing mountain cryosphere and its importance to the water cycle under climate change“, aimed at informing stakeholders …

Guest post by Jenny Snell Icelandic glaciers, like those in many regions around the world, are melting fast1. Ice margins are retreating, and lakes are forming at these margins, called proglacial lakes1. These lakes speed up the loss of ice, change the flow of sediment through rivers, cause coastal erosion and can create a risk …
It’s the first ever ‘International Day of the Glacier’ on 21st March 2025. This is part of the ‘International year of glacier preservation‘, being celebrated world-wide. Why is this being celebrated? Worldwide, glaciers are shrinking. Everywhere we look, glaciers are getting smaller each year; they are melting and losing more ice than they are gaining …
By Gunjan Silwal, OnePlanet Doctoral Student Nepal, a landlocked Himalayan country with 30 million people1, has a strikingly diverse topography. Within just 150–200 km across the width of the nation, its elevation shifts dramatically from the low-lying Terai Plains (~70 m asl) to Mount Everest (8,848 m), the world’s highest peak. This extreme altitudinal variation creates …
Glaciers are important for their beauty, cultural importance, ecosystem services such as water resources, economic value, and potential to raise global sea levels. This is an impassioned plea to recognise the value of our glaciers worldwide, and to protect them to the best of our ability. Globally shrinking glaciers Glaciers exist in pretty well every …
Globally, glaciers are receding, one of the most visual and striking pieces of evidence of the way in which climate change is affecting our planet. The evidence is clear, both in satellite imagery, digital elevation models, and repeat glacier photography. Global scale remote sensing Worldwide, glaciers are shrinking. We know this from satellite measurements, that …

Worldwide, glaciers are being lost. Amongst the most dramatic evidence of climatic warming is the retreat and disappearance of mountain glaciers around the world. Retreat has accelerated worldwide over the last fifty years 1 and we now face the reality of permanent loss of mountain glaciers. Where are glaciers disappearing? The extent and volume of …
Glaciated regions present a wide range of glacial resources, from drinking water to tourism and from hydroelectric power to mining. However, as the climate warms and glacial regions change, these resources are under threat, and communities will need to start adapting in order to maintain livelihoods and economic development. Glacial water resources The first of …
Introduction | Types of glacial lakes | Moraine-dammed | Ice-dammed | Bedrock-dammed | Supraglacial | Subglacial | Summary What are glacial lakes and where are they found? During the last few decades, accelerated ice mass loss and glacial retreat has resulted not only the expansion of existing glacial lakes but also the formation of new …
