Is it true that the number one source for the greenhouse gas Methane in the atmosphere is wet-lands?

Question

Remember "SWAMP-GAS"?
Methane is produced by rotting vegetation and wet-lands are probably the greatest source. It certainly exceeds the volume produce by cows. Even grass allowed to rot on the ground instead of being eaten will produce methane.
It is pumped out of gas wells to be piped to our homes for energy, to power plants to produce electricity, etc.: but those sources are burned and produce carbon dioxide and water.
Atmospheric methane, relative to its quantity, has a far greater effect on global warming than CO2.
What is an appropriate perspective for evaluating the reality of this situation?

Answer 1

It is true that 'swamp-gas' can produce a lot of methane. But this only amounts to some 5% of the total methane production on earth!
By far, human activities, i.e. garbage dumps or land fills, human waste management plants, etc. produce some 60% of the total methane production on earth!!

Answer 2

Is true that wet-lands are a major contributor to the global production of methane, methane is approximately 20 times potent in trapping heat in the Earth’s atmosphere then CO2. However at today’s figures, methane is only contributing to a small percentage when it comes to Global Warming. But by far the greatest concentrations of methane is trapped within the icesheets in and around the poles. When these icesheets melts, a lot more methane will be released, and when that happens, well I’m sure you already know the answer.

Answer 3

Methane is an interesting gas in thaty it comes from a lot of different sources. So no matter what you look at it is not that high of a percentage.

Wetlands are, according to journals, the largest single source of methane.

That being said if you add it all up natural contributions are half that of man made contributions to the atmosphere.

Answer 4

Methane has no effect on our environment. Methane is very light and explosive. There is no lake of methane in our upper atmosphere ,if we did the first airplane to fly through it would explode. We have launched deep space vehicles through where the environmentalist think it is and it hasn't exploded yet.How did the environmentalist measure it, or is all there information a lie???
