Greenhouse gases are formed by burning fossil fuels, so it is the parts of the world that burn most. That means North America, Europe, and China.
1st - China is the biggest polluter with 7,527 MtCO2e in 2007 and -47MtCO2e thanks to reforestation (2000).
2nd - US emitted 7,282 MtCO2e (2008) and -403MtCO2e thanks to reforestation (2000)
3rd - EU emitted 5,045 MtCO2e (2009) and -24MtCO2e thanks to reforestation (2000)
4th - Indonesia 451MtCO2e (2007) and +2,563MtCO2e due to deforestation (2000)
5th - Russia 2,192MtCO2e (2009) and +54MtCO2e due to deforestation (2000)
6th - Brazil 659MtCO2e (2005) and +1,372MtCO2e due to deforestation (2000)
7th - India 1,214MtCO2e (2005) and -40MtCO2e thanks to reforestation (2000)

In addition, the GHG emissions in the world came from (in 2007):
Energy supply - 25.9%
Industry - 19.4%
Forestry (including deforestation) - 17.4%
Agriculture - 13.5%
Transport - 13.1%
Residential and commercial buildings - 7.9%
Waste and wastewater - 2.8%

What is the concentration of greenhouse gases in the air?
The concentration of greenhouse gases in the air, largely water vapor, carbon dioxide and methane, are causing an enhanced greenhouse effect which is global warming.The amounts of greenhouse gases in the air are:5% Water Vapor0.039% CO2Trace (less then 0.001%) small amounts of other gases (methane, nitrous oxide etc)Water vapor absorbs heat like other greenhouse gases.
What percentage does co2 contribute to green house gases?
The most abundant greenhouse gas is water vapor. Although not as potent as other greenhouse gases pound for pound, by sheer volume water vapor is the key greenhouse gas. Carbon dioxide is the second largest (by volume) greenhouse gas. Methane and nitrous oxide complete the four primary greenhouse gases, but there are only trace amounts of these in our atmosphere. Since water vapor is about 4% of the atmosphere, and CO2 concentrations are 400 parts per million, 0.04/0.0004 = 1%. In other words, CO2 is roughly 1% of the greenhouse gas.
How might burning fossil fuels affect the composition of gases in the atmosphere?
Burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity releases carbon dioxide (and other gases). These change the composition of gases in the atmosphere. The present levels of carbon dioxide have increased from 280 ppm (parts per million) one hundred years ago to the present 400 ppm.
How do greenhouse gases cause temperature to rise?
By capturing heat and trapping heat Air pollution (greenhouse gases like carbon dioxide and methane) traps heat in the atmosphere increasing temperature and causing extreme storms. greenhouse gases trap heat.
What is the difference between greenhouse effect and greenhouse enhanced greenhouse effect?
The greenhouse effect is a natural process that keeps the Earth warm. Without it, the earth would be unable to retain enough heat to sustain life.The enhanced greenhouse effect is caused by the all the extra greenhouse gases (carbon dioxide, methane etc) that we put into the air from burning fossil fuels and agriculture (cattle belches). These all trap more heat and radiation from the sun than is normally required. The earth radiates infrared energy from the sunlight that reaches the surface which should escape off into space, but due to the enhanced greenhouse effect, this radiation is trapped. Therefore, the overall temperature of the globe rises.See this link below for a diagram:Global warming is the increase of the average temperature of the earths atmosphere due to the greenhouse effect. The greenhouse effect is caused by high concentrations of methane, co2 and water vapour in the earth's atmosphere . These gases occur naturally (natural greenhouse effect) however due to human activity (cars, burning fossil fuels, deforestation) more of these gases are released, and this enhances the greenhouse effect (so it is called the enhanced greenhouse effect.)
Are greenhouse gases and natural gases ultimately the same?
A1. Natural gas is methane, CH4. It is a greenhouse gas, but far from the only one. Carbon dioxide, CO2, is the one that we are most concerned about.A2. But man made gases such as sulfur dioxide, and the fluorocarbons, (and more) also play their parts.

Greenhouse gases are obviously lighter than air How then are they measured by weight How does one weigh something that is lighter than air?
Greenhouse gasses are NOT "obviously lighter than air"; carbon dioxide is significantly heavier than air.One way to weigh something that's lighter than air is to weigh it in a vacuum.
Is it true that increasing levels of the greenhouse gases could make the earth cooler?
Increasing levels of greenhouse gases lead to a warming of the Earth's atmosphere by trapping heat from the sun. This phenomenon, known as the greenhouse effect, is the primary cause of global warming. Therefore, increasing greenhouse gas levels will not make the Earth cooler.
Can infrared light get through Earth's atmosphere?
Yes, some of it can. Infrared radiation is trapped by greenhouse gases, but not all of it is trapped. These gases only trap radiation in very specific parts of the electromagnetic spectrum, so there are "windows" where it can escape.
Why is the ozone hole larger in Antarctica with not near as many greenhouse gases as say in New York or Chicago?
The ozone hole is larger over Antarctica. It is because CFC's carried in various parts are carried to poles by westerly's.

These change the composition of gases in the atmosphere. The present levels of carbon dioxide have increased from 280 ppm (parts per million) one hundred years ago to the present 400 ppm.
How are greenhouse gases thought to be the cause of global warming?
We know that carbon dioxide and methane are greenhouse gases, that is, they capture infrared heat rising from the surface of the earth, preventing the heat escaping into space.We can measure the amount of these greenhouse gases in the atmosphere, for example, carbon dioxide has been 280 ppm for thousands of years, but now it is over 400 ppm (parts per million).We also measure the temperature, and find it is breaking records almost every month.Other possible causes of temperature rise, for example, solar flares, the earth moving closer to the sun, etc, have all been investigated and proved false.
How can the sun heat the earth now when it was not able to heat it during the ice age?
Now we have far more in the way of greenhouse gases in the atmosphere than during the ice age. Carbon dioxide (CO2) levels over thousands of years have never changed much from 280 ppm (parts per million). Now they are approaching 400 ppm. Extra greenhouse gases in the atmosphere are causing global warming and climate change.
What is happening to greenhouse gases?
Greenhouse gases continue to build up in our atmosphere. Recent measurements for carbon dioxide (CO2) are: Jan 2010: 388 parts per million. Jan 2011: 391 ppm. Jan 2012: 393 ppm. Fifty years ago, in 1960, levels were 318 ppm.
