the site fightglobalwarming.com allows peoples to calculate your personal impact in global warming. After answer some questions user will be informed about the amount of CO2 produced.
Take a time to calculate your amount of CO2. Link here.

My results :

You create 6.0 metric tons of carbon

You could release about the same amount of carbon pollution by cutting and burning all the trees in a section of the Amazon rainforest the size of 0.7 football fields.

Understanding the Heating, Greenhouse Effect consequences, pollution, increase of the world-wide temperature,

Every day we follow in the television, periodicals and magazines the climatic catastrophes and the changes that are occurring, quickly, in the world-wide climate. One never saw so fast changes and with effect devastadores as it has occurred in recent years. Europe has been punished for waves of heat of up to 40 centigrade degrees, cyclones reaches Brazil (mainly the south and Southeastern coast), the number of deserts increases to each day, forts hurricanes cause deaths and destruction in some regions of the polar planet and calotas is melting (factor that can cause the advance of the oceans on littoral cities). What it can be provoking everything this? The scientists are unanimous in affirming that the global heating is related to all these events.

Researchers of the world-wide climate affirm that this global heating is occurring in function of the increase of pollutants, mainly of gases derived from the fósseis fuel burning (gasoline, diesel etc), in the atmosphere. These gases (ozone, carbonic gas and carbon monoxide, mainly) form a layer of pollutants, of difficult dispersion, causing the famous effect greenhouse. The deforestation and the forest fire of forests and bushes also collaborate for this process. The rays of the Sun they reach the ground and they radiate heat in the atmosphere. As this layer of pollutants makes it difficult the dispersion of the heat, the result is the increase of the globe temperature. Although this phenomenon occurs of more evident form in the great cities, already it verifies its consequences in global level.

Consequences of the global heating
- Increase of the level of the oceans: with the increase of the temperature in the world, it is in course the melting of calotas polar. When increasing the water level of the oceans, can occur, future, the submersion of many littoral cities;
- Growth and sprouting of deserts: the increase of the temperature provokes the death of some animal and vegetal species, unbalancing some ecosystems. Added to the deforestation that comes occurring, mainly in forests of tropical countries (AfricanBrazil, countries), the trend is to increase each time more the desert-like regions in our planet;
- Hurricane Increase, tufões and cyclones: the increase of the temperature makes with that bigger evaporation of waters of the oceans occurs, potencializando these types of climatic catastrophes;
- Waves of heat: regions of amenas temperatures have suffered with the heat waves. In the European summer, for example, if it has verified an intense wave of heat, provoking even though aged child and deaths.

Protocol of Quioto
This protocol is an international agreement that aims at the reduction of the emission of the pollutants that increase the effect greenhouse in the planet. It entered in vigor in 16 February of 2005. The main objective is that the reduction of the globe temperature in the next years occurs. Unhappyly the United States, country that more emits pollutants in the world, did not accept the agreement, therefore it affirmed that it would harm the industrial development of the country.

Global warming definition

From Wikipedia, the free encyclopedia

Global mean surface temperature anomaly 1850 to 2006 relative to 1961–1990

Mean surface temperature anomalies during the period 1995 to 2004 with respect to the average temperatures from 1940 to 1980

Global warming is the theory of increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.

Global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the twentieth century. The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations"^[1] via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes have probably had a small warming effect from pre-industrial times to 1950, but a small cooling effect since 1950.^[2]^[3] These basic conclusions have been endorsed by at least 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. The American Association of Petroleum Geologists is the only scientific society that officially rejects these conclusions.^[4]^[5] A few individual scientists disagree with some of the main conclusions of the IPCC.^[6]

Global Warming Could Thin Heat-Trapping Cirrus Clouds

2007-08-16T17:45:00.000-07:00

A study done by the University of Alabama in Huntville disputes the widely, but not completely accepted theory that man-made global warming will accelerate itself by creating more heat-trapping cirrus clouds. To see the complete article take clik the link http://global-warming.accuweather.com/
