Oh, look, you have found another subreddit where to pose as an "expert" when in fact you are nothing but a fraud.

In the meantime let's see what the actual experts are saying in IPCC AR5 (which I still see that you insist on not reading, even if would almost certainly result in you looking stupid much less often than you do now):

TS.2.8.3 Methane

The concentration of CH4 has increased by a factor of 2.5 since pre- industrial times, from 722 [697 to 747] ppb in 1750 to 1803 [1799 to 1807] ppb in 2011 (Figure TS.5). There is very high con dence that the atmospheric CH4 increase during the Industrial Era is caused by anthro- pogenic activities. The massive increase in the number of ruminants, the emissions from fossil fuel extraction and use, the expansion of rice paddy agriculture and the emissions from land lls and waste are the dominant anthropogenic CH4 sources. Anthropogenic emissions account for 50 to 65% of total emissions. By including natural geologi- cal CH4 emissions that were not accounted for in previous budgets, the fossil component of the total CH4 emissions (i.e., anthropogenic emis- sions related to leaks in the fossil fuel industry and natural geological leaks) is now estimated to amount to about 30% of the total CH4 emis- sions (medium con dence). {2.2.1, 6.1, 6.3.3}

In recent decades, CH4 growth in the atmosphere has been variable. CH4 concentrations were relatively stable for about a decade in the 1990s, but then started growing again starting in 2007. The exact drivers of this renewed growth are still debated. Climate-driven uctuations of CH4 emissions from natural wetlands (177 to 284 ×1012 g (CH4) yr–1 for 2000–2009 based on bottom-up estimates) are the main drivers of the global interannual variability of CH4 emissions (high con dence), with a smaller contribution from biomass burning emissions during high re years {2.2.1, 6.3.3; Table 6.8}.
