A UN report shows that the rate of accumulation of CO 2 and other gases is increasing year after year It will soon be 17 years from the signing of the Kyoto Protocol that drove reducing emissions of greenhouse gases. Part of the protocol referred to CFC s already being eradicated because of another also deleterious effect on the atmosphere was fulfilled: the destruction of the ozone layer; but the most important reducing CO 2 emissions from the combustion of hydrocarbon energy to achieve, not only it hasn’t been met but that emissions have increased. A report commissioned by the United Nations Intergovernmental Panel on Climate Change (IPCC) shows that in the last 30 years CO 2 is still accumulating in the atmosphere, it also shows an acceleration almost double the rate of accumulation was in the 80s . The consequence is clear the average temperatures increases, due to the greenhouse effect, the effect caused by CO 2 and other gases, decreases the amount of heat rele...
