Methane is an atmospheric trace gas like CO2!
Maybe it is the fluctuations of solar activity of the sun and not these trace gases that cause global warming and cooling!
According to Google search: "Atmospheric methane concentrations reached a record high of over 1,900 parts per billion (ppb), or approximately 1.9 parts per million (ppm), in 2021, which is about 260% of pre-industrial levels" and "As of early 2026, the global average atmospheric CO2 concentration is approximately 427 parts per million (ppm), marking a roughly 50% increase since the Industrial Revolution (280 ppm)."
"Solving the mystery of a methane surge ... Methane is the second most important radiative forcing agent [???] among all the anthropogenic trace greenhouse gases, with a climate warming effect second only to carbon dioxide. Therefore, it is important to understand why its atmospheric concentration changes. Its global atmospheric abundance [???] is growing steadily but not monotonically, and the question of what factors are responsible for the variability the methane growth rate is a key one.
The long-term secular rise of atmospheric methane concentrations is, unsurprisingly, due largely to anthropogenic methane emissions from agriculture, the oil and gas industry, and waste management, which together contribute more than half of all global methane emissions. ..."
