Glaciers around the globe are melting faster than ever, with the last three-year period seeing the largest glacial mass loss on record, according to a UNESCO report released on Friday (March 21).
The dramatic ice loss, totalling 9,000 gigatonnes since 1975, is expected to continue accelerating and could lead to a flood of economic, environmental and social problems as sea levels rise while key water sources dwindle.
“It would be an ice block the size of Germany with the thickness of 25 metres. That’s the ice we lost since 1975 from glaciers,” Michael Zemp, director of the world glacier monitoring service, said during an embargoed press conference unveiling the report in Geneva on March 13.
“Glaciers might disappear on the current melting rates within this century,” Zemp said, adding that five of the last six years registered the largest losses, with glaciers losing 450 gigatonnes of mass in 2024 alone.
The accelerated melting has made mountain glaciers the largest contributors to sea level rise, put millions at risk of devastating floods and hurt water flows that billions depend on for hydroelectric energy and agriculture.
Stefan Uhlenbrook, the director of water and cryosphere at the World Meteorological Organization (WMO), said about 275,000 glaciers remain globally, which, along with the Antarctic and Greenland ice sheet, comprise about 70% of the world’s fresh water.
“We need to advance our scientific knowledge, we need to advance through better observing systems, through better forecasts and better early warning systems for the planet and the people,” Uhlenbrook said. “Preserving glaciers is not only an environmental imperative, it’s really a survival strategy.”
Mountain glaciers have led to an estimated 25 mm (0.98 in) in sea level rise, with 1 mm expected to be added each year. Each millimetre could mean an additional 300,000 people at risk of floods, Zemp said.

Most glaciers are in fact advancing. They go thorough a natural cycle
If they never stopped advancing, they would have wrapped around the earth by now
Billionaires better cut back on their private jet travels
Have Bill Gates take his fingers out of the global experimentations he undertakes
Or cut back on the drilling exploration in Antarctic
Indian uneducated people and whole world industrial pollution air ash is responsible. We can se Ash is on the top of ice then sunlight not reflect hence ice will melt faster .
