摘要

Changes in global average temperatures and of the seasonal cycle are strongly coupled to the concentration of atmospheric CO_2. I estimate transfer functions from changes in atmospheric CO_2 and from changes in solar irradiance to hemispheric temperatures that have been cor- rected for the effects of precession. They show that changes from CO_2 over the last century are about three times larger than those from changes in solar irradiance. The increase in global average temperature during the last century is at least 20 times the SD of the residual temperature series left when the effects of CO_2 and changes in solar irradiance are subtracted.
