The Heihe River Basin is experiencing significant climate change, leading to higher temperatures and increased rainfall. This has caused glaciers to shrink, snow lines to rise, and water quality to deteriorate. The increase in temperature has also led to higher agricultural water consumption and an overall decrease in water resources. The researchers analyzed data from the past 50 years to understand these changes and found that the climate in the basin has changed significantly, with temperatures rising faster than the global average. Overall, the impact of climate change on the hydrology and water resources in the Heihe River Basin is evident through these observed changes.
