Quote:Just because a molecule contains carbon does not mean it captures heat energy.

Before you permit yourself to get all scare-defied over more methane being released into the atmosphere, and even if you buy into recent (since WWII) surface temperature rise being as a result of increased greenhouse gasses, do your research and find that methane is an irrelevant gas in the theoretical causes because of the limited bands of energy it can possibly absorb and from those two bands upon which it can act, it must share that potential with one more prevalent, which has already done the job almost completely in those bands leaving nothing much for methane to work upon. Those who promote gloom & doom from impending release of stores of methane wrongly assume the gas would have unlimited stores of energy upon which it could draw to heat the planet should that release occur. Therein lies the failure of this sub-theory even assuming such release is possible and imminent. There is no such pool of energy.

The energy beamed by the sun comes to Earth in the form of short waves, is absorbed by the planet, and some is transmitted back to space in the form of long waves in various bands of energy. Warmists’ Anthropogenic Global Warming Theory holds that greenhouse gasses intercept by absorption and transmit back to Earth a percentage of the long wave radiation energy in the form of kinetic heat in natural balance until humans destroy the balance by over supplying unnatural amounts of greenhouse gasses by which such process and added heat causes more of the principle greenhouse gas, water vapor, to be produced accelerating the process in an ever heightening loop of heating Gaia. Methane is a “greenhouse gas.” The misnamed process acts nothing like a greenhouse, BTW, and empirical measurements, the acid test of science, do not reflect water vapor increasing as required in proportion to CO₂ increases or even out of proportion. No increase of water vapor at all in fact has been measured among the several failures of the theory to be sustained by empirical measurement.

Methane (CH4) by its physical properties has only two narrow absorption bands at 3.3 microns and 7.5 microns in the overall broad electro-magnetic spectrum from which it can absorb energy. Theoretically, CH4 is 20 times more effective an absorber than CO2 – in those bands. However, CH4 is only 0.00017% (1.7 parts per million) of the atmosphere. Moreover, both of its bands occur at wavelengths where H2O is already absorbing virtually all energy. Because water vapor is much more plentiful in the atmosphere than methane (or any other GHG), H­2O absorbs vastly more energy and is by far the most important greenhouse gas. On any given day, H2O is a percent or two of the atmosphere (1.0-2.0% or 5,882 to 11,764 times as prevalent as methane in the atmosphere, or 5882÷20=294.1 [or 588.4] multiple the absorber as methane); we call that humidity. Hence, any radiation that CH4 might absorb has already been absorbed by H2O in the only radiation bands methane absorbs energy. Once the energy in a band of the spectrum has been sucked dry, no additional absorptive gas can absorb more. Painting a black window another coat will not keep out more light. In other words, the ratio of the percentages of water to methane is such that the effects of CH4 are completely masked by H2O because the absorption of infrared energy in the bands of the spectrum affected by methane has already been saturated by H2O absorption. The amount of CH4 would have to increase 100-fold to make it comparable to H2O and even then it would no longer matter because water vapor has beat it to the punch.

There is not much ambient energy in those two little short, stray bands of the radiation spectrum to start with and most of that has already been worked over by H2O from time immemorial leaving only the scraps to poor CH4, which can never effect climate to any appreciable or worrisome amount. Because it absorbs energy in a laboratory does not mean it works that way in a chaotic atmosphere with other agents and processes present.

Methane is fine vehicle to instill fear, the politicians greatest ally, on an uninformed populace though. It is the rare person whose knowledge on the substance reaches even the level of understanding the stuff coming from their gas stove is raw methane…easy targets for manipulation.
It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies.
