Climate Change in the Nepal Himalayas: What we know and what we need to know

This study reports synthesis of a systematic literature review on climate change observations, projections, impacts, and research gaps and needs in the Nepal Himalayas. The major findings on climate change observations are rising temperature trends across all geographical regions in Nepal, increasing occurrences of temperature and precipitation extremes, increasing loss of glacier mass, and increase in glacier lake formations. Literature on nationwide trend analysis report lack of consistent long-term trend in precipitation, contrary to others at watershed scale, which show trend in both directions. A study on stream-flow trend in Nepal suggests absence of stream-flow trend in most of the stations and general lack of spatial trend.
