Air temperature and precipitation are fundamental measurements for describing the climate, and can have wide-ranging effects on human life and ecosystems. Rainfall, snowfall, can all affect the amount of water available for drinking, irrigation, and industry. Annual and seasonal temperature and precipitation patterns also determine the types of animals and plants (including crops) that can survive in particular locations. Changes in temperature and precipitation can disrupt a wide range of natural processes, particularly if these changes occur more quickly than plant and animal species can adapt.
The maps below show the linear trend of temperatures and precipitations change from 1991 to 2020 at pixel level (UNEP/GRID-Geneva based on the CRU TS 4.05 dataset). CRU TS (Climatic Research Unit gridded Time Series) is a widely used climate dataset on a 0.5° latitude by 0.5° longitude grid over all land domains of the world except Antarctica. It is derived by the interpolation of monthly climate anomalies from extensive networks of weather station observations. Citation: Harris et al (2020).
