The Voices of Glaciers: A Human Chronicle of Ice, Loss, and Resilience
In the tropics, glaciers are melting at an alarming rate – transforming landscapes, disrupting lives, and erasing cultural memory. The Voices of Glaciers is a powerful new book funded with the support of the MRI that shares the personal reflections of 35 individuals – from Indigenous elders to scientists – who are witnessing this change firsthand.
Glaciers have long stood as silent sentinels of Earth’s climate: keepers of ancient ice, guardians of biodiversity, and vital water sources for millions. Yet in the tropics, these icy giants are disappearing faster than almost anywhere else on the planet. Their loss is not only physical – it is cultural, emotional, and scientific.
The Voices of Glaciers, a powerful new publication from UNESCO and the French Research Institute for Sustainable Development (IRD), brings this story vividly to life through the testimonies of 35 individuals – scientists, Indigenous leaders, artists, mountain guides, park rangers, tourists, and young environmental advocates – whose lives are intimately connected to tropical glaciers in the Andes, East Africa, and Southeast Asia.
At its heart, the book is a rare convergence of science and storytelling. It pairs glaciological research and visual documentation with deeply personal accounts of witnessing change: the grief of elders who remember snow-capped peaks now bare, the resolve of researchers tracking ice loss, and the hope expressed by young climate advocates who refuse to give up on the future. Through themes of care, concern, sadness, adaptation, and resilience, The Voices of Glaciers offers a uniquely human lens on one of the most pressing indicators of climate disruption.
“We propose thinking about each of the voices in this book as a different vantage point and emotional world from which to perceive melting tropical glaciers,” says book author Ignacio Palomo, a researcher at the IRD and the Université Grenoble Alpes, and a member of the MRI Science Leadership Council. “All have lived experiences that shape their perceptions and knowledge, and we acknowledge the diversity of their worlds and world-making practices, while using emotion as a point of encounter.”
The data behind each of these stories is stark. Since the 1980s, the Andes have lost between 30 percent and 50 percent of their glacier mass. By 2050, nearly half of the tropical glaciers documented in the book—including five UNESCO World Heritage Sites and several Biosphere Reserves—may be completely gone. Most of the rest will have lost up to 90 percent of their surface area compared to their extent during the Little Ice Age. These projections signal risks to water security, cultural heritage, biodiversity and local economies in some of the most vulnerable regions on Earth.
The Voices of Glaciers not just a chronicle of loss, however. It is also a testament to adaptation, memory, personal dedication, and hope. The book draws from an interdisciplinary approach that integrates sustainability science, anthropology, glaciology, and Indigenous knowledge, reflecting the complexity and interdependence of cryospheric systems and human societies. It reminds us that rigorous data and climate models must be complemented by emotional truth and local perspective if we are to grasp the full scope of what is being lost, and what may still be saved.
As the international community marks the International Year of Glaciers’ Preservation 2025 and launches the Decade of Action for Cryospheric Sciences (2025–2034), The Voices of Glaciers arrives as both a timely contribution and a call to action. Because to protect glaciers is not only to preserve nature, biodiversity, and vital water resources, but also to honour the people and cultures shaped by them.
