TRANSPORT ECOLOGY AND ANTHROPOGENIC GLOBAL WARMING

Heavy critics claim that a group of Western scientists has put together the prepositions for Kyoto protocol. The Kyoto protocol limits the production of the following six components with anthropogenic activities: carbon dioxide, methane, nitrous oxide, per fluorocarbons, sulphur hexafluoride and hydro fluorocarbons. The most dangerous role is assigned to carbon dioxide, so, on that basis, the elimination of carbon dioxide production is proclaimed as ecological success. The escalation is continued in such a pace, that clean technologies (?), clean fuels (?), clean vehicles (?) and similar are defined. The controversy over global warming gets even more complicated when you include politics, economics, greed, and the self interests of the various governments, NGOs and companies. Astronomer Milutin Milankovic studied changes in the orbital eccentricity, obliquity, and precession of Earth's movements. Such changes in movement and orientation change the amount and location of solar radiation reaching the Earth. He hypothesized that when some parts of the cyclic variations are combined and occur at the same time, they are responsible for major changes to the Earth's climate (even ice ages). The next stage of power train and fuel strategy involves using new high economy combustion engines that can be run with partially renewable fuels and used worldwide. Researchers are hard at work exploring new fuels, engines and vehicle technologies - but there are not clean cars, clean energy or full renewable fuels. Contrary to popular belief, electric vehicles don’t hold all the emission answers, until the electric power comes from coal-fired power stations or part renewable sources (hydro, wind and sun).
