Hoss, old boy, you need to stop listening to the stupid bozo deniers. Of course the scientists take into account the contributions of CH4. And , in fact, track the CH4 levels.Something to consider if I was a Global Warming nut.
Methane (CH4) is a far more dangerous greenhouse gas than CO2, according to the Intergovernmental Panel on Climate Change (IPCC).
The IPCC’s latest report, released this past Monday, reports that methane is 34 times stronger a heat-trapping gas than CO2 over a 100-year time scale. Methane’s current global-warming potential (GWP) is 34, nearly 40% increase from the IPCC’s previous estimate of 25.
Over the course of 20 years, methane has a global warming potential of up to 86, up from its previously calculated 72. This is far higher than CO2. The problem: most climate change studies do not take this increase into account.
The pressing issue: Hydraulic fracturing, or fracking, as it is called, is alive and well and seen by many as a more environmentally friendly way to extract natural gas. Opponents have long known that fracking can lead to ground water contamination, denigrated air quality, contaminated water, and raised CO2 levels.

Methane levels over the Arctic Ocean are higher than elsewhere on Earth. As the animation below shows, methane levels were as high as 2436 parts per billion (ppb) on the afternoon of December 5, 2016, with most methane rising up from the water, in particular over the Arctic Ocean.
While, for most of the world the CH4 level is 1800+ ppb, up from 700 ppb pre-industrial level, you can see that for some areas of the Arctc, the levels are over 2400. That would indicate the present source of the present increase is from the warming of the permafrost and ocean clathrates.
