Despite continuous reports and stark warnings, from authorized sources, global air pollution continues worsening and global temperature increasing.These facts motivated us to present in this paper, new contributions from our theoretical-practical work on gasoline Combustion Optimization by Magnetic Action, (COBMA) in mobile sources, started in 2008.So far, global implementation of electric cars, and important proven actions, have not succeeded.Consequently, there is a low probability of implementing globally the proven magnetic action.We are convinced that if enough proven actions are not promptly implemented, we will have very soon a problem of catastrophic dimensions, worse than that of the present pandemic.With the aggravation that once, the sensitive stable balance of the Earth-Atmosphere system become unstable there will not be any action to restore it.Therefore, we continue making contributions, attempting to present, through the condition of the Atmosphere balance, a more comprehensive view of the real Climate-Change problem, and to attract the attention of organizations leading the Earth´s environmental protection, to considering global implementation of COBMA, despite they are devoted to assisting the international agreements, supported on diplomatic promises that, so far, have not globally accomplished its main goals due to the political and socio-economic gaps between countries.That view is based on information analyses, from authoritative sources and our points of view from experience.Its purpose is to favour global Climate-Change Comprehension, unavoidable for synergistic work and consequent mitigation of the anthropogenic impact on the Climate system.These ideas characterize our papers.The main goal of this paper is to show, from fuel consumption records, and gases emissions results obtained in Cartagena, Colombia, April-November 2019, in a Renault-Steway car, that excessive HC and CO emissions reductions, by magnetic action are unsuitable; though reduce considerably fuel consumption also contribute to increase CO2 emissions impact to the atmosphere.
