Introduction:
We have to know the world is ours, but everything in the world have a interaction with everything. So, if the humans affect their lives, they affect the world.
History of the Global Warming:
Svante Arrhenius was a Swedish scientist who realized that fossil fuelscould be the cause that makes the Earth warm. He could see the relationship between temperature and carbon dioxide in the atmosphere. He discovered the natural greenhouse effect.
Thomas Chamberlin knew they were the human activities which could cause the carbon dioxide to be added to the atmosphere and make the climate increase.
After these investigations, everybody believes that the damage themen did was very low and oceans would help to eliminate that damage.
Gilbert Plass in 1955 concluded the carbon dioxide atmosphere, that was joined to the infrared rays, are the cause of the damage to the ozone layer and then the Earth will be overheating. The carbon dioxide lives 10 years in the atmosphere.
What is Global Warming?
Maybe the global warming is because of the over production ofenergy, or the exploitation of the industry and transport or maybe it was because the humans use more and more chemicals in the agriculture.
The atmosphere has 3 functions to protect us: filter, shield us and cover us from the UV. But we are damaging the ozone layer and we are intensifying the greenhouse with the emissions of methane and the carbon dioxide.
The carbon dioxide, which is thefirst gas that is damaging more the ozone layer, is the 77% of the enhanced Greenhouse effect and the 80% of the carbon dioxide is in the industrialized countries. The carbon dioxide appears because we use a lot of combustible and we make changes in the Earth as the felling of trees and removal the agricultural lands because without the trees and plants is the 20% of the Greenhouse effect.
Thesecond gas is the methane. It has the 14% in the scale global. It is produced by some bacteria during decomposition of organic matter with not too much oxygen. But, the livestock, rice cultivation, landfills, sometimes the coal mining, leaking oil and natural gas help it. The methane is able to retain heat 23 times more than the CO2, but it remains less.
So, when the Greenhouse is intensifying, theatmosphere is having more warm temperatures and it is heat in the Earth. When the temperature increases of unnatural, this phenomenon is called Global Warming.
An inconvenient truth, Al Gore:
When we see the movie, I really like it because it explains us the really truth about what it´s happening in the world, but it tell us how could change our future for good, too. If we do or do not dosomething, we will have to take the consequences. And the consequences could be good or bad.
He talked about the heat waves that maybe we are going to have. The example was the heat wave in Europe in 2004. We will have more like these. This heat wave will make droughts in many places. We are not going to have another option to take this seriously.
The movie is about the glaciers in decades. Theconcentrate carbon dioxide and methane in the atmosphere is warming the global temperature causing the melting of the glaciers. If this happen, the ocean will be more extensive. This will make many cities couldn´t survive. So, the overpopulation will be increasing more and more.
If this happen, what will happen to the animals which live in the glaciers that we are melting? They won´t survive. Itwill be more endangered animals.

Solutions to minimize Global Warming:
One of the most important solutions about the global warming is the Kyoto protocol. The Kyoto protocol is an agreement about every state will decrease the percent of their emissions of not good gases to the atmosphere. For example: the CO2, methane, nitrous oxide, and fluorinated industrial gases.
Another solution could be...
