    Abstract: Carbon dioxide, methane, nitrous oxide and three groups of fluorinated gases have been referred to as greenhouse gases and the most offensive gases in contributing to Global Warming This invention comprises the use of Titration and other chemical oxidation—reduction reactions in novel ways to scrub these gases from the Earth's atmosphere. The invention comprises identifying, developing, and spraying base aerosols to neutralize carbon dioxide, nitrous oxide, sulphur dioxide, and similar compounds whose oxides form acids when dissolved in water vapor. Acid-base titrations result in neutralization of the acid and the base. The formation of a salt and water typically are by-products. Salt precipitates such as CACO3—calcium carbonate or limestone settle into the oceans naturally forming limestone deposits which act as homes for microscopic sea life. Carbonic acid which results from CO2 being dissolved in water produces calcium carbonate when treated with a base.
