US EditionNearly 40% of the World’s Glaciers Are Already Doomed, Scientists Say
- Scientists published a study in Science showing that 39 percent of the world’s glacier mass is already committed to melting globally.
- The study modeled over 200,000 glaciers across eight glacier models and simulated ice loss under various climate scenarios, with some regional losses more severe than others.
- If current climate policies remain unchanged, global temperatures are expected to rise by 2.7 degrees Celsius by 2100, resulting in the loss of approximately 76 percent of today’s glacier volume and causing sea levels to increase by a minimum of 113 millimeters .
- Co-Lead author Lilian Schuster highlighted that even very small increments in temperature increases have significant impacts, while co-author Harry Zekollari noted that meeting ambitious climate goals could still preserve many crucial glaciers.
- The findings suggest urgent action is needed to protect glaciers that support water supplies, ecosystems, and coastal stability for billions of people worldwide.

39 percent of the 2020 amount will definitely melt permanently, but if current climate policy continues, this number could be 76 percent.
By Issy Ronald, CNN The world's glaciers are in a sorry state, with nearly 40% of their total mass already doomed to melt even if global temperatures were to stop rising immediately, according to a new study. Researchers estimate that glaciers will eventually lose 39% of their mass by 2020, a trend that is already irreversible no matter what comes next and will likely contribute to a 113 millimeter rise in global sea levels. The loss increases t…
New study: Significant global glacier loss inevitable
If global temperatures rise by 2.7 degrees Celsius – in line with current climate policy – only a quarter of the glacier masses will be left. This is the result of an international study involving the University of Bremen, which has been published in Science journal. If global temperatures rise by 2.7 degrees Celsius – in line with current climate policy – only a quarter of the glacier masses will be left. This is the res…
Western Canada's glaciers 'doomed' to disappear
Climate change has put Western Canada's glaciers on track for devastating loss over the coming decades, with the southern half of B.C. expected to lose nearly 75 per cent of the alpine ice - even if warming stops today, a new study has found. The planet has so far warmed an average of about 1.2 deg...
