【 摘 要 】

A linearized global heat balance model which is driven byfive classes of influence on long wavelength radiation and four classes of influence on short wavelength radiation is calibrated against historical estimates of global average temperature. Additional influences are variability of solar irradiance and the initial global average temperature at the end of pre-industrial period. Industrial activities perturbs the concentration of CO2, CH4, N2O, tropospheric ozone, other greenhouse gases, and contrails in the atmosphere. Also, anthropogenic influences on short wavelength radiation including effects of land use changes on albedo, anthropogenic tropospheric aerosols and stratospheric ozone and black carbon on snow, effects of volcanoes, and variable solar irradiance are considered. The "climate sensitivity" of global average temperature response to these influences accounts for the "ice albedo" effect of global average temperature changes on absorption of short wavelength radiation and the influence of temperature changes on atmospheric water. Using the data-calibrated model, global average temperature is extrapolated to the year 2220.
