Have you probably observed that when the directly low car is left the sunbeams in a sunny day, the interior of the car warms a lot but that the external air and is the question for that the automobile acts like a trap of heat?
This is due to that the glass, in the grosores commonly used transmits, more than 90% of the radiation in the visible range. This causes an increase in the temperature as a result of the energy created in the car. The effects of this heating are known as effect hothouse.

The effect hothouse is also manifested, to more scale on the Earth. The surface of the Earth that warms during the day as a result of the absorption of the solar energy, cools down at nights irradiating you leave its energy toward the deep space as infrared radiation. The dioxide of carbon, the vapor of water and appearances of some other gases like methane and nitrogen oxides act like a blanket and they conserve tibia to the Earth at night for the blockade of the heat that is irradiated from the Earth. For it is that they are called "hothouse gases". However the dioxide of carbon is different, because the human activities contribute a difference in the concentration of this in the atmosphere.
The effect hothouse allows the life since on the Earth preserve the lukewarm Earth around the 30ºC hotter. However excessive quantities of these gases harm the delicate balance catching too much energy, what originates an increase in the temperature of the Earth and the climate change in some towns. These undesirable consequences of the effect hothouse are known as the global heating.
A great concern
According to the different scientific studies, supported by the UN, it is calculated that in the year 2100, the half temperature of the Earth will be between 1,5 and 6 grades more than that of 1980. And it is that the temperatures are rising to global scale, and the 15 hotter years since one has registration (1867) they have happened from 1980.
This is the great concern of the scientists, since the polar helmets melt. Also, the heat of the sun, when it arrives to the poles, it is reflected again toward the space. And, when melting the polar caps, minor is the quantity of heat that is reflected, that he makes that the earth warms even more. With this, more water of the oceans will evaporate, and in other sides there will be torrential rains, floods, winds huracanados, droughts, waves of heat and icy... among other natural disasters, famines and epidemics could also take place, those that would be frequent in all the countries. They could also melt floes, to disappear flora and fauna, to become desérticas the cultivation lands, to be ruined reefs and to be flooded the islands of the Caribbean.
The worst thing of everything is that ourselves is those that we are "collaborating" with the global heating of our habitat when using fossil fuels (coal, petroleum and their derived as paraffin, liquefied gas and benzine), to allow the industrial contamination, among other, and the destruction of forests and humid lands.

I`m very interested in your explanation of the global warming, but I have a question ¿how do you think is the most important thing to do to prevent this disaster?
I agree with you about we're responsables, but we have a chance to change our planet future. Your explanation was very good, and also I think if you had gotten more historical information it would be better.
Great article! I liked the example of cars you used, it was nice! Another thing I think was good, is that you used information from the documentary we watched on wednesday. Only a couple of words escaped to you and you wrote them in spanish: vientos huracanados=hurrican winds, and tibio=warm.
Thank you.
