Climate Change Causes Rapid Reduction of Ice in Great Himalayas: CAS Researchers
Glacier volume of Himalayan is reducing rapidly due to climate change, leading to cascading effect of alpine ecosystem there, a study by CAS researchers found recently.
The cascading effects of rising temperatures and loss of ice and snow in the region are affecting, for example, water availability (amounts, seasonality), biodiversity (endemic species, predator–prey relations), ecosystem boundary shifts (tree-line shifting, high-elevation ecosystem changes), and global changes (monsoonal shifts, loss of soil carbon), found Xu Jianchu, researcher of Key Laboratory of Biodiversity and Biogeography, Kunming Institute of Botany, CAS.
The result was published on Vol. 23, Conservation Biology, a flagship journal of the Society for Conservation Biology, also the most frequently cited conservation journal in the world.
According to the study, climate change will also have environmental and social impacts that will likely increase uncertainty in water supplies and agricultural production across Asia. A common understanding of climate change needs to be developed through regional and local-scale research so that mitigation and adaptation strategies can be identified and implemented.
The Greater Himalayas hold the largest mass of ice outside Polar Regions and are the source of the 10 largest rivers in Asia. Challenges brought about by climate change in the Greater Himalayas can only be addressed through increased regional collaboration in scientific research and policy making.
