What part does methane have in global warming?

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.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
