The paper shows a several kinds of present aspects on global warming and the possibility of its prevention by the improvement of fossil fuel combustion. Although the application of electro-magnetic combustion technique makes it possible to attain at the most three percents of energy saving rate, it is possible to realize the Kyoto protocol by taking the electro-magnetic combustion technique together with the development of high efficiency heat transfer mechanism using the electro-magnetic technique depending on CO_2spectrum.
