Saying that it causes global warming may be a bit of an overreach.
However, it is a greenhouse gas, 21 times more dangerous than carbon dioxide, and could certainly be a contributing factor.

∙ 11y agoMethane is a dangerous greenhouse gas, twenty times more powerful than carbon dioxide. So it is contributing to global warming.
Methane is largely the same as natural gas, a fossil fuel. It is also being released by melting tundra, by belching cattle, and by some animal manure.
A:At present, a relatively small part. But that can drastically change.As a greenhouse gas, methane is much more powerful then for example carbon dioxide. Over a 100 year period an emission of methane has 25 times the impact on temperature then a carbon dioxide emission.
But the emissions of man-made methane today are relatively low when compared to those of carbon dioxide.
Yet there is a threat: there are huge quantities of natural methane gas trapped in permafrost (soil which has been frozen uninterrupted for long periods of time) and which are situated primarily in the Arctic regions of Russia. The temperature increase which the earth is already experimenting today (as a result of the global warming caused by carbon dioxide) could melt this permafrost and thus release those large amounts of methane into the atmosphere.
Scientists believe that earlier mass extinctions of species on earth (particularly the Permian--Triassic extinction event in which it is estimated that 96% of all marine species were killed) could have been caused by a natural event which released similarly large amounts of trapped methane.
Methane is a very potent greenhouse gas.
A:Methane is a greenhouse gas, which absorbs some of the heat being reradiated from the earth as infrared radiation, preventing it from escaping into space. However, not all greenhouse gases are the same: each gas block infrared at particular wavelengths only, allowing the radiation to pass through at other frequencies. If we imagine infrared radiation, which is invisible to us, as having many different colours in much the way visible light does, then different greenhouse gases would have different colours. Methane blocks about 21 times as much infrared radiation as does carbon dioxide, another common greenhouse gas.Yes, methane is a greenhouse gas, 21 times more powerful than carbon dioxide. It escapes from agriculture and animal farming as well as from melting tundra. A substantial amount escapes from coal gas fracking.

∙ 11y agoMethane is a powerful greenhouse gas. Additional emissions from agricultural practices like cattle rearing and pig farming, as well as from the melting of permafrost, tundra and frozen lakes, are increasing the levels of greenhouse gases in The atmosphere , causing global warming which in turn is responsible for climate change.

∙ 13y agoMethane is a greenhouse gas that is twenty times as potent, molecule for molecule, as carbon dioxide. It can therefore be a very important contributor to global warming. Fortunately, it is at extremely low atmospheric concentrations, but society needs to minimise any increase in levels.

∙ 11y agoThe Greenhouse effect is when heat is prevented from radiating into space by the Earth's atmosphere.
Most of us have heard all about how Carbon Dioxide (often truncated to "carbon") emissions contribute to the greenhouse effect. Methane is 21-times more effective at trapping heat in the atmosphere than carbon dioxide by weight.
Total Greenhouse Gas Contributions as a percent of total Greenhouse Effect:
(Corrected for GWP/Global Warming Potential, heat retention characteristics)
95.000% -- Water Vapor
3.618% -- Carbon Dioxide
0.360% -- Methane
0.950% -- Nitrous Oxide
0.072% -- Other (CFC's, etc.)

The methane affects the earth temperature because of the greenhouse effect.

∙ 12y agoYes, methane is the major constituent of natural gas, a fossil fuel. So burning it releases carbon dioxide into the atmosphere.
If methane is not burnt, but released into the atmosphere, as happens from pipe leaks, agriculture, melting tundra and other things, then it is a greenhouse gas 21 times more powerful than carbon dioxide. So it is better to burn it.
Wiki User
∙ 11y agoCarbon dioxide and methane are both greenhouse gases. Greenhouse gases hold the earth's heat in the greenhouse effect. Too much of these gases is causing global warming.
Carbon dioxide (CO2) and Methane (CH4) are transparent to visible light energy but somewhat opaque to thermal or infrared radiation or energy.
They allow light energy in but block the out going radiation somewhat, precisely the way glass in a greenhouse does. Hence the name greenhouse gases.

∙ 11y agowell, basically, using humour in my answer, it keeps the earth warm because when cows release methane (via belching) It goes up into the atmosphere (as well as making it spell bad) and does the same as CO2. Methane absorbs infrared radiation very well, and as its concentration increases earth's temperature does too.

What pressure will condensate drop out of methane gas form and become liquid condensate hydrocarbons?
If you are asking how much pressure you would have to compress methane to in order to liquify it at room temperature, the answer is that methane won't liquify at room temperature. The critical temperature for methane is -87.2 degrees centigrade. Above that temperature it will not liquify no matter how much pressure you apply. At -82.7 degrees centigrade it would take a pressure of 45.96 bar to get it to liquify. See: http://www.chem.purdue.edu/gchelp/liquids/critical.html
What are the physical state of methane in room temperature?
Methane is a gas at standard temperature and pressure, also at room temperature unless the room in question is very cold!
Why is methane a gas at room temperature?
beacuse it is becaiuse its called methane and starts with a M and ends with E :)
Is methane a metal?
Methane is not a metal. It is a hydrocarbon with the chemical formula CH4.
Where is methane produced?
Methane is found in the Earth's crust. It is also produced by certain microbes and by cows during their digestive process.
Is titan the only moon known to hold liquid water?
Titan has no liquid water, it is too cold. But it does have oceans of methane. On Earth the temperature is way to hot for methane to be in liquid state. But on the cold surface of Titan the temperature and atmospheric pressure is just right for methane to exist in liquid form.Similar to how the temperature on Earth is just right for water to exist in liquid form.
How does location on earth affect temperature?
The equater.
How does greenhouseeffect affect the air?
Increasing the temperature of the earth atmosphere.
How does ozone layer affect the temperature?
Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth's atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die

Does the distance from the sun affect the earth's temperature?
Because of the Earths atmosphere, the distance from the Sun, does not affect the temperature on the surface of the Earth. In the northern hemisphere, we are closer to the Sun in winter and the furthest away in summer.
How does atomospheric composition affect air temperature?
While the specifics of this are controversial, the generally held beliefs are that greenhouse gases cause air temperature to rise. The primary greenhouse gases in earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone. For an extreme view of how greenhouse gases can affect temperature, do some research on Venus where greenhouse gases and the proximity to the sun have turned the planet into a furnace
How does each factor affect earth's temperature?
The earth's temperature is affected by wind and precipitation. These two factors help to cool down the temperature when its hot. Without them, the earth would begin to over heat.
What are the physical state of methane in room temperature?
Methane is a gas at standard temperature and pressure, also at room temperature unless the room in question is very cold!
Can an earthquake be caused by temperature?
Not by temperature variations at Earth's surface, no. However, temperature variations in Earth's mantle play a role in plate tectonics, and so can affect earthquake activity.
How did gravitational contraction affect earth?
Gravitational contraction raised the temperature of Earth early in it's formation.
What substance is methane at room temperature?
The chemical compound of methane is CH4, in a molecule there are 4 hydrogen atoms joined to 1 carbon atom. Methane is also a gas at room temperature, and it odourless and colourless.
