The largest source of CO2 emissions globally is the combustion of fossil fuels such as coal, oil and gas in power plants, automobiles, industrial facilities and other sources.
CFCs (chlorofluorocarbons) are man-made gases that are also greenhouse gases.
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.
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.
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.
According to the phrase, it may seem that way, but actually, no, they do not.The phrase "greenhouse gas" is simply a metaphor describing the ways carbon dioxide and other gases in the atmosphere can trap heat emanating from the earth just the way a greenhouse traps warmth for plants to grow.
CFCs (chlorofluorocarbons) are man-made gases that are also greenhouse gases.
Natural sources of these gases include volcanic eruptions, wildfires, and decomposition of organic matter. Man-made sources include burning fossil fuels, industrial processes, and deforestation. Both natural and man-made sources contribute to the levels of these gases in the atmosphere.

Hydrofluorocarbons (HFCs) are a group of man made greenhouse gases present in a wide variety of consumer products including technical and medical aerosols.
Certainly man-made as all these greenhouse gases that we humans are letting off from our cars, factories etc.

Yes, the US Supreme Court has authorized the Environmental Protection Agency to treat carbon dioxide, the major man-made greenhouse gas, as a pollutant.
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.

Anthropogenic greenhouse gases are gases released into the atmosphere as a result of human activities, such as burning fossil fuels, deforestation, and industrial processes. These gases, like carbon dioxide and methane, trap heat in the Earth's atmosphere and contribute to global warming and climate change.
