Man's involvement with the annual production of greenhouse gas is tiny. In total, we produce about a third of one percent. Even when we strip away the major greenhouse gas, which is water vapor, man produces only 3% of the gas that is generated.

My personal contribution to the greenhouse gases in the atmosphere is tiny, and I do what I can to reduce even that contribution. However, the contribution of all humans since the beginning of the Industrial Age is quite disturbing. The concentration of carbon dioxide has increased during that time by more than 35 per cent, from the long-term range of 260-280 parts per million (ppm) to the present level of over 380 ppm. During the twentieth century alone, we added around 1000 billion tonnes of carbon dioxide to the atmosphere. We are continuing to add more than 30 billion tonnes of carbon dioxide to the atmosphere each year.
The greenhouse effect warms the gases in the atmosphere.
The glass or plastic walls of a greenhouse represent greenhouse gases in the atmosphere by trapping heat energy inside, much like how greenhouse gases in the Earth's atmosphere trap heat.
They slow the loss of heat
If the amount of greenhouse gases increased, it would lead to a stronger greenhouse effect, trapping more heat in the Earth's atmosphere and causing global temperatures to rise. On the other hand, if the amount of greenhouse gases decreased, it would weaken the greenhouse effect, resulting in cooler global temperatures.
If the amount of greenhouse gases increased, then the temperature on Earth would likely rise due to the enhanced greenhouse effect trapping more heat. Conversely, if the amount of greenhouse gases decreased, the temperature on Earth could potentially decrease as less heat is trapped.

No, greenhouse gases are part of the atmosphere, which is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases including methane. Air also contains a variable amount of water vapor, on average around 1%.

This is an interesting question that gets deeper then you may wish to go. A shuttle launch will release water vapor, which is a greenhouse gas. It is the most common of greenhouse gases. Water vapor is ignored though in terms of man contribution to greenhouse gas because it dissipates quickly and mans contribution to this gas is insignificant. The water vapor produced in a launch remains in the atmosphere for a few hours. Much of the raw material used to create this water vapor also comes from the atmosphere to start with. Man produces almost 0.3% of all greenhouse gases, virtually none of this amount though is from the space program.
No, they are gases that enter the atmosphere.
The geological record shows both the amount of greenhouse gasses in the atmosphere and the past temperature of the planet.
Greenhouse gases keep the earth warm.Too much greenhouse gas is causing global warming.
Greenhouse gases trap heat in the Earth's atmosphere, contributing to the greenhouse effect and potentially leading to global warming. Examples of greenhouse gases include carbon dioxide, methane, and water vapor.
Greenhouse gases extend very high. They extend in the troposphere.
