Global warming is increasing permanently, because the concentration of CO 2 in the atmosphere is rising continuously. According to National Oceanographic and Atmospheric Administration, the concentration of CO 2 in the atmosphere was 407 ppm in June 2016 and 413 ppm in April 2017 as a last record for now. If the effects of other greenhouse gases, such as CH 4 , N 2 O, SF 6 , NF 3, chlorofluorocarbons, hydrofluorocarbons, perfluorocarbons are added, the effective concentration may reach or exceed 550 ppm CO 2 -equivalent.  According to the United Nations Intergovernmental Panel on Climate Change-2014 Climate Change Report, this is about two times higher than 278 ppm CO 2 concentration in the pre-industrial year 1765. Thus, very urgent solutions must be found. The aim of this article is to suggest a vital, fast and very meticulous solution using NH 3 gas in the atmosphere in order to decrease the atmospheric CO 2 without delay. The laboratory experiments in the gas phase for (NH 3 + CO 2 ) reaction showed us that to use NH 3 gas in the atmosphere will be a very fast, effective method for decreasing CO 2 concentration of atmosphere.  (NH 3 + CO 2 ) reaction is also quantitative in the cold atmosphere strata and there will be no more free ammonia in the atmosphere and no public health problem.
