What is it about?

This research article aims to assess trends in annual and seasonal air temperature and precipitation and a range of extreme climate indices for the high-altitude regions in Asia using a consistent dataset over the entire high mountains of Asia.

Why is it important?

For the high-altitude mountainous regions, which are a significant source of water for the large rivers in Asia, the climate has changed in recent decades. Climate warming will have enormous consequences for hydroclimatic extremes and this article addresses these issues. The changes imply substantial increases in the future occurrence of hazards such as floods, landslides, and droughts, which in turn impact economic production and infrastructure.


This research demonstrates the trends in extreme climate indicators have spatial and seasonal variability. If these historical trends persist in the future, a most likely scenario, an increase in flood, drought, heatwave, landslide, and compound hazards may be expected. These hazards will have severe impacts on the overall livelihood and ecosystem of High Mountain Asia and thus require urgent adaptation policies at the local and regional levels.
