CO2 causing global warming

Increased solar activity (increased solar irradiance) has contributed to global warming in the past, but for the last 40 years global temoerature has been steadily increasing in parallel with atmospheric carbon dioxide (CO2) while solar irradiance has essentially remained the same i.e. it is increased CO2 in the atmophere that is causing the increased global temperature.
