Global warming is a term used to refer to the phenomenon of the increase in global average temperature of Earth's atmosphere and oceans, since 1850, coinciding with the end of the so-called Little Ice Age, [1] or either Regarding longer periods. [2] This increase would have increased in the last decades of the twentieth century and the first century.
Global warming is associated with climate change that may have anthropogenic cause or not. The main effect that causes global warming is the greenhouse effect, a phenomenon that refers to the absorption-by certain atmospheric gases, mainly CO2-energy part of the floor beams, as a result of being heated by solar radiation. The natural greenhouse effect that stabilizes the Earth's climate is not a matter to be included in the global warming debate. Without this natural greenhouse temperatures would drop by about 30 ° C, with such change, the oceans would freeze and life as we know it would be impossible. To this effect occurs are required these greenhouse gases, but in appropriate proportions. What worries climate scientists is that an elevation of that ratio will produce an increase in temperature due to heat trapped in the lower atmosphere.

The greenhouse effect is a natural atmospheric phenomenon that keeps Earth's temperature by trapping some of the energy from the Sun The increased concentration of carbon dioxide (CO2) from fossil fuel use has led to the intensification of the phenomenon and the consequent rise in global temperatures, melting polar ice and rising sea levels.
Water vapor, carbon dioxide (CO2) and methane gas are a natural layer in Earth's atmosphere that traps some of the energy from the Sun The use of fossil fuels and deforestation has resulted in increased concentrations CO2 and methane and other gases such as nitrous oxide, which increase the greenhouse effect. (See Annex 1)
The Earth's surface is heated by the sun But it does not absorb all the energy but reflects some of it back into the atmosphere. (See Annex 2)
About 70% of solar energy reaching the Earth's surface back into space. But part of the infrared radiation is retained by the gases that produce the greenhouse effect and returns to the surface. (See Annex 3)
As a result of the greenhouse effect keeps the Earth warm enough to make life possible on Earth. In the absence of the phenomenon, the climatic fluctuations would be intolerable. However, a small change in the delicate balance of global temperature can cause serious damage. In the past 100 years the Earth has increased between 0.4 and 0.8 º C in average temperature. (See Annex 4)
In recent years there have been various hypotheses and measures regarding the global warming problem, which has caused, and is still causing disasters and climate change around the world, causing great human and material losses, for these reasons I wanted to report, prevention and awareness of our colleagues, it was decided to include in this study, results obtained by the evil and relentless use of products that threaten the environmental balance and thus the stability and welfare of all beings that inhabit planet Earth.
Referring to the result of the greenhouse effect, is cited several incidents, and is similarly named which may occur or that it will try to reduce all or part of their appearance in the future, all this was achieved at the convocation various measures and precautions enhanced by large corporations and the early clarification of the use of certain substances, as well as the disappearance of some of these that are primarily responsible for such damage on the planet.
