Abstract

Synchronized control of both global warming and ozone depletion is prerequisite for the sustainable stability of our bio-diversity. Here we uncover the importance of Paris Agreement and Kyoto Protocol and the new impact of Montreal Protocol to protect stratospheric ozone by considering the prototype H₂O + O(¹D) → 2OH insertion/addition reaction as the representative reaction of potent GHG molecules with steady state O(¹D). While CO₂ via its continuous regeneration CO₂ + O(¹D) → CO₂ + O(³P) reaction in stratosphere is involved in ozone hole formation, the geoengineering via nonstop CaCO₃ injections in stratosphere in future would also be responsible for ozone hole formation. Moreover, the classical nature of single potential wells of single step exothermic barrierless reactions governed by quantum mechanics de-energizes the energized adducts or products analogous to energy conservation of a falling mass from some height under gravity and plays decisive role in the extent of pressure independency of rate constants.
