The cyclic set of natural transfers of carbon (also called: Global Carbon Cycle) is built with the following physicochemical and bacteriological processes: 1) atmosphere to green plants or soil transfers; 2) animals or plants to atmosphere transfers; 3) burning fossil fuels to atmosphere transfers; 4) animals (including humans) to soil transfers; 5) atmosphere to oceans transfers, etc. This whole cycle (despite its obvious complexity), is a formal proof that disturbances recorded by carbon cycle described above, inevitably alter the chemical composition of the atmosphere and, therefore, lead to climate change whose magnitude depends on the sensitivity of the atmosphere relative to the changed settings. The weather models used to assess climate change caused by CFCs, have the annoying tendency to neglect the contribution of clouds to the global carbon balance. Yet it has been proven by C. Mbane in 2015 that clouds are composed of only two elements (dry air and saturated water vapor); and that clouds’ saturated water vapor may form precipitation (solid or liquid) if and only if they met and dissolve condensation nuclei (mainly the carbon dioxide (CO2) in the case of Troposphere). In other words, atmosphere absorbs a significant amount of CO2 in the formation of rains. The purpose of our work is to make it clear to the international opinion that cloud’s saturated water vapor is the true lung of our planet, far ahead of the green plants respiration or photosynthesis those take place only under the influence of sunlight and in the very lower layers of the troposphere (e.g., well below 25 meters from the surface of the earth). Each of us could then easily understand the link between GCCD (Global Carbon Cycle Disruptions) and the upsurge of WCWSWHR (weather conditions with strong winds and heavy rains).
