A chemical reaction is presently taking place in the troposphere: carbon dioxide and water vapor interact at low temperature resulting in a very slow reaction rate. The purpose of this publication is to advance the acceleration of such and ultimately regulate the total carbon dioxide in the planet. Usual techniques in improving reaction kinetics are employed. A state formulation with redundant measurements, together with the identification of a reaction state transition matrix is presented. Measurement monitoring and the mathematics keep track of the concentrations of water vapor and carbon dioxide to guide aeration decisions in each state zone.
