Ladakh glacier melting study

A study in the journal 'The Cryosphere' analyzed 12 glaciers in the Zanskar region of Ladakh from 1992 to 2023.
Findings indicate that Zanskar glaciers are moving 2.4 m/year slower per decade on average.
Surface thinning rate increased from 0.22 m/year (2000-2005) to 0.57 m/year (2015-2020).
Mechanism: Glacier thinning reduces driving stress, which slows ice flow; this limits the replenishment of lower glacier sections from higher accumulation zones.
Zanskar glaciers are high-altitude, receiving winter snowfall primarily from mid-latitude westerly disturbances.
Glacier behavior is influenced by local factors including geometry, debris cover, and terminus conditions.
Implications: Long-term glacier water storage is declining, potentially impacting water security, agriculture, and hydropower in the Indus basin.
Experts emphasize the need for more ground-based measurements (ice thickness, mass balance, temperature) to validate satellite-derived data.

Chinese researchers report a significant link between global warming and glacial retreat on the Tibetan Plateau.
Glacial area on the Tibetan Plateau has decreased from 51,000 sq. km to 39,000 sq. km over the last 60 years.
Glaciers in the southern part of the plateau, including the Himalayas, Gangdise, and Nyenchen Tanglha Mountains, have shrunk by approximately 40% in six decades.
The overall shrinkage of glaciers across the entire Tibetan Plateau is recorded at 24%.
Melting glaciers have led to an increase in the number and size of glacial lakes, with over 14,000 now mapped on the plateau.
Researchers warn of heightened risks of Glacial Lake Outburst Floods (GLOFs) and landslides, particularly near the southern borders of China.
Experts emphasize the urgent need for enhanced mapping of glacial lakes and international data sharing to mitigate downstream disaster risks.

Newest first. A story that ran for 28 days is exactly the kind the mains paper asks about as one question.
