What other greenhouse gases are there besides carbon dioxide?

Answer 1

There are many gases capable of being greenhouse gases, but fortunately not many occur naturally in siginificant amounts.

Carbon dioxide is the greenhouse gas most responsible for global warming or climate change, but it is not the most potent greenhouse gas, nor the most abundant.

Water vapour is the most abundant greenhouse gas. Although it is responsible for the long term natural warming of the earth, it does not contribute to climate change.

The second most important greenhouse gas for climate change is methane. Although present in very small proportions, it is around 21 times more potent as a greenhouse gas than is carbon dioxide.

Another naturally occurring greenhouse gas is ozone. This gas also helps prevent harmful ultraviolet radiation from reaching the earth, so its presence in the upper atmosphere is important to us.

Answer 2

The most talked-about "greenhouse gas" is carbon dioxide, but other gasses are far more significant and effective in trapping planetary heat. Some of them are:

1. Water vapor.

2. Methane, which is naturally produced by rotting vegetation; "swamp gas" is primarily methane. Methane also comes from landfills and dumps. The most humorous form of methane is from flatulence.

3. Nitrous oxides

Answer 3

A "greenhouse gas" is any gas that contributes to the process known as the "greenhouse effect".

The greenhouse effect is a process which causes incoming heat from the sun to become trapped in the Earth's atmosphere. The heat is repeatedly absorbed by the gas in the atmosphere, emitted back into the atmosphere, and then reabsorbed by the gas.

This effect is vital for the survival of life on Earth, as it is this process that enables the Earth to maintain a suitable temperature. However in common parlance, when people refer to the greenhouse effect, they are usually referring to what is known as a runaway greenhouse effect.

A runaway greenhouse effect is when the layer of heat absorbing gas has reached such levels that the Earth's temperature rises sharply. The inability of heat to escape and the continuing influx of heat from the sun causes all surface water to evaporate, and further thicken the cloud layer, which in turn causes even more heat to become trapped.

This process could, if left unchecked, eradicate all life on the planet and see surface temperatures of hundreds of degrees celsius.

Typically when people refer to greenhouse gas, they are referring to carbon dioxide. This is the gas that causes most concern to climate scientists as it is by far the most commonly emitted gas, and contributes the most to the global warming process.

Answer:

The seven main Greenhouse Gases include the following plus water. Water is usually referred to as a special case as it is generated by Earths oceans and difficult to control :

• Carbon Dioxide - CO2
• Methane - CH4
• Nitrous Oxide - N2O
• Sulphur Hexafluoride - SF6
• Perfluorocarbons - PFC's
• Hydroflourocarbons - HFC's

Answer 4

Gases causing the enhanced greenhouse effect, apart from carbon dioxide, are

• Methane
• Nitrous Oxide
• Ozone

The enhanced greenhouse effect is causing global warming, which is causing climate change.

Answer 5

Hydrogen is not a greenhouse gas. Greenhouse gases must have at least three atoms in order to sustain enough energy to be considered as such. Ozone is O3 and has no hydrogen and is a powerfull greenhouse gas. Water vapor though is the most common and strongest in terms of total affect (80% or better).

Answer 6

Greenhouse gases include water vapour, carbon dioxide, methane, sulfur haexafluoride and CFCs

Answer 7

it is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range.
