General Causes:

Currently every one on this planet is trying to find a solution for global warming, but before we find the solution we must know the causes (of the global warming).

There are many causes of this phenomenon, such as greenhouse gases, volcano eruptions, solaractivites and variations in the earth orbit. However, scientific believe that the main cause is human actpivity such as emission from cars, factory emissions and other. Actually, these activities produce carbon dioxide from burning of gas, oil and coal. Therefore, this carbon dioxide affects the earth when it goes to the atmosphere and concentration there. In conclusion, the climate of the earth will be warm because the present climate is not in equilibrium like before.

One Cause:

After we have looked at the general causes of the global warming, let’s now turn our attention to one significant cause which is the greenhouse gases. First of all, they contain carbon dioxide, water vapor, methane, nitrous oxide and chlorofluoro carbons and ozone. Those gases have the ability to hold and absorb the heat in the surface of the earth. Actually, it works as a mirror. To elaborate, when the heat from the sun comes to the earth, then it goes to the sky, but, unfortunately it collides with the greenhouse gases and goes back again to the earth. Also, we cannot ignore the fact that greenhouse gases are beneficial because they preventing the earth form becoming an ice planet. Finally the greenhouse gases has been increasing over the last 50 years.

General Effects:

Now, let me mention the several effects of global warming. There are many effects of global warming on the environment and on human life. It lead to increase in the sea level, because the temperature increased gradually therefore the ice glaciers melt and that means a large part of the earth will sinking or disappear of increase the volume of the water. Another, significant effect is the global climate. This will reduce the agricultural production because the plant will not find the perfect climate to grow, so large numbers of animals and humans how depend on vegetarian food will be affected by this. In addition, the change in the temperature can help spread tropical diseases such as malaria and hepatitis.
In conclusion, the change in climate will increase the risk of flooding, lack of water through evaporation, snow pack decline and an increase in storms and hurricanes, so the global warming is a serious disaster and we must find a solution.

One Effect:

As I mentioned before global warming has several effects on the earth and for human life. However, let me deal with one major effect of this phenomenon, which is the rising in the sea level and oceans. According to scientists has raised approximately 130 meters since 1800 year ago, when the ice melts due to the climate change because of the greenhouse gases building up on the atmosphere. In addition, if we can not stop this increasing, eventually, perhaps many parts of land will disappear, such as the Maldives, Shanghai and other parts of the earth, thus there will be more loses of human shelter, animals and food sources. Finally, what can we say is we have to do some thing or we will be crying for our planet.
