Abstract: The recent Covid 19 outbreak, and the measure enforced to limit the spreading of the virus, from airlines grounded, factories shut down, business close down, citizens confined in their homes, have translated in a drastically reduced anthropogenic carbon dioxide emission. This experiment permits to test the hypothesis if the anthropogenic CO2 emission is the overwhelming contributor to the atmospheric CO2 concentration and global warming, or if the anthropogenic CO2 emission has a limited effect on the atmospheric CO2 concentration that is driven by the temperature, and which would be the effect of prolonged, unprecedented cuts in anthropogenic carbon dioxide emissions of the atmospheric CO2 concentration.

Keywords: Covid 19; anthropogenic CO2 emission; atmospheric CO2 concentration.
