Yes, climate
change is putting nearly all glaciers across the Himalayas in severe danger,
causing them to melt and retreat at accelerating rates.
Current
Dangers to Himalayan Glaciers
- Rapid Melting: Research by
the International Centre for Integrated Mountain Development
(ICIMOD) shows that glacier ice loss in the region has doubled since
2000.
- Volume Loss: Scientists warn that these
glaciers could lose up to 75 percent of their total volume by the end of
the century if global greenhouse gas emissions do not decrease.
- Thawing Permafrost: Permafrost is soil that
has stayed frozen for hundreds of years. As temperatures rise, this frozen
glue thaws and weakens mountain rock faces.
- Catastrophic Collapses: Weakened ice and rock lead
to dangerous events like sudden glacier collapses, severe landslides, and
floods from bursting glacial lakes.
Downstream
Impacts
- Water Insecurity: According to the United
Nations, shrinking glaciers threaten the freshwater supplies, food
production, and hydropower relied upon by nearly two billion people
downstream.
- Increased Disasters: Melting ice feeds unstable
glacial lakes, making sudden and destructive flash floods much more common
across South Asia
