Melting Glaciers and the Rising Threat of Mountain Flooding

• Glaciers in High Mountain Asia are increasingly transforming into unstable lakes that threaten communities downstream when natural moraine dams fail.
• A recent disaster in Nepal highlights the growing risk of catastrophic floods and landslides caused by collapsing ice and water.
• Scientists project that if carbon dioxide emissions remain unchecked, up to 75% of remaining glaciers in the region—encompassing the Himalaya, Karakoram, Pamir, Hindu Kush, and Tien Shan—could be lost by 2100.

Accelerating Ice Loss

• A 20-year international study revealed that the rate of annual glacier ice loss accelerated by 36% in the second half of the study period (2012–2023) compared to the first (2000–2011).
• Annual loss now averages 273 billion tonnes, a figure that is 18% greater than that of the Greenland Ice Sheet and over double the loss from Antarctica, posing a significant risk to global sea-level rise projections.

Global Impact and Industry Criticism

• Roughly 2 billion people, or 20-25% of the global population, live downstream from glaciers and are at risk from Glacial Lake Outburst Floods (GLOFs).
• Research published in Oxford Open Climate Change identifies the fossil fuel industry as the root cause of the climate crisis, noting that its multi-billion-dollar disinformation campaigns have hindered necessary policy actions to phase out fossil fuel dependence.
