Results for the experiment minus control cases. (Statistics for a case with double pre-industrial atmospheric CO2 content and a case with an engineered globally uniform 1.84% reduction in solar insolation. The engineered simulation is consistently more similar to the control pre-industrial climate. The climate engineered case (Global_1.84) has a globally uniform 1.84% reduction in solar insolation. This reverses approximately 95% of the global warming, but reverses 127% of the global increase in precipitation.)
