1. Climate Regions
Temperatures are rising four times faster in China . Tibetan glaciers are retreating at a higher speed than in any other part of the world. In the short term, this will cause lakes to expand and bring floods and mudflows. In the long run, the glaciers are vital lifelines for Asian rivers, including the Indus and the Ganges. Once the glaciers vanish, water supplies in those regions will be in peril.
