Land use affects the global climate through greenhouse gas and aerosol emissions, as well as through changes in biophysical properties of the surface. Anthropogenic land use change over time has caused substantial climate forcing related to albedo, i.e. the share of solar radiation reflected back ...
With this in mind, historical land use practices that directly impact dryland biocrusts (e.g., grazing, wildfire, land conversion) may have had past influence on the global climate, as well as produced subsequent feedbacks to climate change as in increased aerosol emissions and surface albedo33,...
Drylands represent the planet’s largest terrestrial biome and evidence suggests these landscapes have large potential for creating feedbacks to future climate. Recent studies also indicate that dryland ecosystems are responding markedly to climate change. Biological soil crusts (biocrusts) ‒ soil surfac...
Global climate change 2.4Albedo and climate change Albedois the measurement of reflectivity of sunlight by any object (Hall and Qu, 2006). Objects reflecting more sunlight have high albedo while those reflecting less have a low albedo. It is measured on a scale of 0–1 or given in percentage...
Anthropogenic LULCC, including urbanization defined as the expansion of urban land here, affects local-to-global climate not only through modifications in surface roughness, carbon pro- cesses, and turbulent heat fluxes, but also through changes in surface albedo that directly alter the Earth's ...

Land cover change affects surface radiation budget and energy balance by changing surface albedo and further impacts the regional and global climate. In this article, high spatial and temporal resolution satellite products were used to analyze the driving mechanism for surface albedo change caused by ...
wood harvest-induced alterations of surface albedo and other biophysical factors affect climate12,13. The magnitude and direction (warming or cooling) of biophysical climate effects vary and are strongly site-specific14,15. Alteration of surface albedo directly affects the global radiation balance12,16...
Vegetation affects the reflectivity, oralbedo, of the Earth's surface, the land surface parameter having the largest influence on the surface radiation budget. Albedo is the integrated reflectance over the solar spectrum (0.0–4.0μm) and is lower for vegetation than for bare soil (Table 2) be...
