Glaciers worldwide are melting quicker and more broadly than previously thought, according to a study published in the journal Science. The findings, released just as global leaders assemble in Tajikistan for the first United Nations glaciers conference, show that limiting global warming to 1.5°C could save more than twice as much glacier ice as current climate policies, which would drive warming to 2.7°C.

According to a new study published in the journal Science, if global temperatures rise by 2.7°C due to existing climate policy, only 24% of the world's glaciers will remain.

 Impact  | 
 Affected Areas  | 
| 
 Water Security in South Asia  | 
 Himalayan glaciers, key sources for major rivers, are depleting—threatening agriculture, drinking water, and hydroelectric power during dry seasons.  | 
 India, Nepal, Bhutan, Bangladesh  | 
| 
 Sea-Level Rise and Coastal Risk  | 
 Glacier melt contributes to rising sea levels, posing risks to coastal cities and island nations.  | 
 Maldives, Coastal Indian cities (e.g., Mumbai, Chennai)  | 
| 
 Ecosystem Disruption  | 
 Alters mountain biodiversity and alpine ecosystems; increases risk of Glacial Lake Outburst Floods (GLOFs).  | 
 Himalayan region, downstream river basins  | 
| 
 Socioeconomic Consequences  | 
 Water scarcity can lead to migration, resource conflicts, and worsening poverty in vulnerable communities.  | 
 South Asian rural and urban areas  |
