Land use changes affect extreme temperatures



Days with extreme hot and cold temperatures—the extremes that tend to be associated with serious socioeconomic consequences—are predicted to occur more often as Earth's climate changes due to human activity. These changes in extreme temperature days are affected by anthropogenic forcings, including greenhouse gas emission as well as land use change. The land use change effects on temperature extremes have been less well studied. Changes such as clearing forests for grassland can alter the climate through changing reflectivity (albedo) of the surface, through hydrological effects, and through changes in carbon dioxide emission or uptake.
