Humans produce the greenhouse gases of carbon dioxide (by burning coal, oil and natural gas, all fossil fuels), as well as some methane from our landfill practices and our pig and cattle farming. We also still emit some CFCs and other halon gases.

What is meant by the term greenhouse effect listing the three most significant greenhouse gases?
The term "greenhouse effect" is made up of two different effects: "Natural and Man-made". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earth's natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and natural gas). The three most significant green houses gases and the amount they contribute are water vapor (80%), carbon dioxide (6%) and methane (1%). Nature produces 99.7% of all green house gas emissions.
What is a greenhouse gas that exclusively anthropogenic?
CFCs (chlorofluorocarbons) are greenhouse gases that are entirely made by human endeavors. All other greenhouse gases (carbon dioxide (CO2), methane CH4, etc occur in nature as well as being produced by man.
How many greenhouse gases are there?
There are many gases which contribute to the greenhouse effect. Some are have a more potent effect than others. The following are considered to be greenhouse gases, the number after the name indicates the equivalent greenhouse gas effect compared to carbon dioxide (the principle man made greenhouse gas:Water vapour (H2O) = ?Carbon dioxide (CO2) = 1Methane (CH4) = 21Nitrous oxide (N2O) = 298Sulfur Hexafluoride (SF6) = 22,200Chlorinated fluorocarbons (CFC's) = 1000 to 9000Notes:1. Water vapor is an odd one in the list as it is naturally occurring. It may be responsible for more than 30% of the greenhouse effect2. CFC's include many different compounds.
The greenhouse effect is due largely to what?
It is caused by humans emitting harmful gases and chemicals into our Earth's atmosphere.Further information:Earth has both a "natural" greenhouse effect and a "man-made" greenhouse effect.The natural greenhouse effect is caused mostly by water vapour, and to a much smaller degree, to carbon dioxide, methane, and a few other minor gases. These factors help keep the Earth warm and habitable.The "unnatural" greenhouse effect is what results from the burning of fossil fuels and rainforest trees, which release extra carbon when they are felled and burnt.
What are anthropogenic greenhouse gases?
Anthropogenic means made by humans, so the greenhouse gases caused by man are mostly carbon dioxide and some methane, and some CFCs.
Is the fallowing sentence true or false the greenhouse effect is a natural process?
The greenhouse gases present in the earths atmosphere are both naturally produced and man made. The natural greenhouse gases (methane, water vapour, carbon dioxide) make the Earth warmer than it would be without the Greenhouse effect (this allows it to be habitable). The addition of man made greenhouse gases (methane, carbon dioxide and a few others) increases the temperature past the natural levels. SO the greenhouse effect is both natural and a result of human activities. If you consider the opposite of a "natural effect" to be a "supernatural effect" resulting from gods, devils or ghosts -the greenhouse effect is natural with no supernatural contribution.
The greenhouse effect is caused by the warming of?
The planet(s) through solar radiation and the retention of a small portion of this heat through atmospheric gases. The greenhouse effect is caused by the warming of the greenhouse gases in the atmosphere, mostly water vapor and carbon dioxide. This is a natural effect that has gone on for millions of years. The enhanced greenhouse effect, what we are experiencing now, is caused by the warming of the extra greenhouse gases that man is adding to the atmosphere, largely by burning fossil fuels, and by deforestation.

Is global climate change man-made?
Yes it is. It's a by-product of burning fossil fuels, which release greenhouse gases, including Carbon Dioxide. It is also a side effect of deforestation and intensive livestock farming, which releases methane. In effect, our presence has resulted in a change in balance between the removal of greenhouse gases from the atmospehere and the production of greenhouse gases.
What gases are associated with the greenhouse effect?
There are many gases which contribute to the greenhouse effect. Some have a more potent effect than others. The following are considered to be greenhouse gases, the number after the name indicates the equivalent greenhouse gas effect compared to carbon dioxide (the principal man made greenhouse gas:Water vapour (H2O) = ?Carbon dioxide (CO2) = 1Methane (CH4) = 21Nitrous oxide (N2O) = 298Sulfur Hexafluoride (SF6) = 22,200Chlorinated fluorocarbons (CFC's) = 1000 to 9000Notes:1. Water vapor is an odd one in the list as it is naturally occurring. It may be reponsible for more than 30% of the greenhouse effect.2. CFC's include many different compounds.
What are the artificial green house gases?
CFCs (chlorofluorocarbons) are man-made gases that are also greenhouse gases.
Is the greenhouse effect really responsible for global warming?
Yes, the greenhouse effect is a natural phenomenon which has existed here for trillions of years and protected the earth from global freezing like the ice age. But increases in greenhouse gases mostly carbon dioxide caused by man's burning of fossil fuels is causing an enhanced, or accelerated greenhouse effect which is responsible for global warming.

Are greenhouse gases affecting the earth?
At present man-made greenhouse gases, carbon dioxide (CO2) and methane, are adding to the greenhouse effect. The natural carbon cycle is unable to cope with the extra CO2 which remains in the atmosphere gathering heat, and causing global warming. Less than 1% of the gases in Earth's atmosphere are called greenhouse gases. Even though they are not very abundant, these greenhouse gases have a major effect. Carbon dioxide (CO2), water vapor (H2O), methane (CH4), nitrous oxide (N2O), and a few other gases are greenhouse gases. They all are molecules composed of three or more atoms, bound loosely enough together to be able to vibrate when they absorb heat. Eventually, the vibrating molecule will emit the radiation again, and it will likely be absorbed by yet another greenhouse gas molecule. This process is called the greenhouse effect and keeps heat near the Earth's surface. All of the green house gases that are mentioned in the above answer are not necessarily man made. They are all natural gases in our environment. The jury is still out on whether we make enough to cause severe climate change as is claimed.
What is global warming and the greenhouse effect?
The greenhouse effect is the way the greenhouse gases (water vapour, carbon dioxide, methane etc) in the atmosphere trap the sun's heat to keep the planet warm. This effect is supported by the water and carbon cycles of the earth, and has been going on since life began.Global Warming is the warming of the earth during the past 200 years but especially since about 1970. Man discovered and started burning fossil fuels (coal, oil and natural gas) which releases carbon dioxide into the atmosphere that had been hidden away for millions of years. This extra CO2 is disrupting the natural greenhouse effect and is causing the enhanced greenhouse effect.It is this enhanced, or accelerated, greenhouse effect that is responsible for global warming.A:Global warming, as the word has been used in recent years, is an increase in average temperature of the earth due to an increase of greenhouse gases. Greenhouse gasses are gases that trap a great deal of heat. These include CO2 and Methane. Anthropogenic global warming is a certain type of global warming caused by human production of greenhouse gases through the burning of fossil fuels and by deforestation.The Greenhouse effect is the phenomenon of heat from the sun being trapped by greenhouse gases in Earth's atmosphere.
