Global Warming

The effect of global warming is, at the origin, a natural phenomenon. It makes it possible the temperature of the low Earth’s atmosphere to be maintained around 15°C on average. Without this famous effect of greenhouse, the average temperature of the surface of the ground would border -18°C, which would prohibit any form of life. To explain this mechanism (global warming), let us consider the heat radiated by the sun. This one is absorbed partially by the ground and the living organisms of planet. In same time. All that is on the surface of the sphere emits infra-red raies in direction of space. Whereas they penetrate in the atmosphere, these infra-reds cross nitrogen and oxygen but are stopped by the steam mainly, carbon dioxide (CO2) or methane: gases “global warming”. These gases thus form a heating cover for planet. But if there is too much CO2, the phenomenon of effect of greenhouse enrayge and the Earth is subjected to an overheating. Thus a vast majority of scientists explain the current reheating of planet.
