Glacier melt is occurring faster than ever before, with new data
Glacier melt is occurring faster than ever before, with new data showing record levels of ice loss over the past three years. According to a UNESCO report released today, the dramatic acceleration of glacier retreat poses a serious threat to coastal populations, water security, and global ecosystems.
Scientists warn that rising global temperatures, driven by fossil fuel emissions, are pushing glaciers worldwide past a critical tipping point. “The preservation of glaciers is a matter of survival,” said Celeste Saulo, Secretary-General of the World Meteorological Organization (WMO), marking the first-ever World Glacier Day.
Glacier Melt Reaches Unprecedented Levels
Since 1975, the world has lost approximately 9,000 gigatons of glacial ice—equivalent to a block the size of Germany, 25 meters thick, according to Michael Zemp, Director of the World Glacier Monitoring Service (WGMS).
The melting of glaciers—from the Arctic to the Alps, and Tibet to Latin America—is expected to accelerate further, contributing to rising sea levels and threatening critical freshwater reserves.
Zemp noted that five of the last six years recorded the highest glacier melt ever, with 2024 alone seeing a loss of 450 gigatons of ice mass.
