Title: Climate change is caused by the absorption of energy ultraviolet by oxygen. Author; Rogelio Pérez C Summary; The problems of climate change occur primarily by an increase in the temperature of the planet. The Science teaches that the heat in the earth originates mainly after the solar constant, by a greenhouse effect caused by greenhouse gases that absorb infrared energy (heat), therefore the problem of global warming, is described as an increase in the greenhouse effect, caused by the increase of greenhouse gases, because of human activity (anthropogenic), pointing mainly to fossil fuels such as Greatest threat facing the planet. But the amount of atmospheric gases, which absorbs the infrared energy or heat, is only 0.04%, and 99.9% of the atmosphere does not absorb heat, so we can conclude that this percentage is not significant, to originate enough heat in the atmosphere of the Planet. In contrast, oxygen (21%) of atmospheric gases, by absorbi
