Climate impacts vegetation type, biomass and diversity. Evidence from observations of the climate system has led to the conclusion that human activities are contributing to a warming of the earth's atmosphere. To better understand the linkages between climate change and land degradation, it is important to identify the sources and sinks of carbon, aerosols and trace gases. Characteristics of the land surface are an important part of the climate system and changes of vegetation type can modify the characteristics of the regional atmospheric circulation and the large‐scale external moisture fluxes. Land use and land cover changes influence carbon fluxes and greenhouse gas emissions that directly alter atmospheric composition and radiative forcing properties. Impacts of climate variability, especially through extreme events such as droughts, sand and dust storms, floods, heat waves, wild fires etc., on land degradation are explained with suitable examples. Technologies, policies, and measures to address the linkages between climate and land degradation are discussed.
