Аннотация:The article gives a scientific analysis of the role of methane in global climate change. The dominant view is that methane, the second most important greenhouse gas, has been considered alongside with the point of view of the non-anthropogenic origin of global climate change. It is shown that the anthropogenic impact is much weaker than the effect of natural processes, among which is the turnover of the ‘main greenhouse gas’ – Н2О. The view that its concentration does not change does not correspond to reality, since a constant amount of Н2О is maintained by the accelerating and slowing down of the turnover cycle. A similar mechanism of self-regulation is shown in the article for methane. Its content in the atmosphere is regulated by its natural short-period transformation in the atmosphere. Comparison of the degree of methane influence on the climate on the basis of analysis of the global warming potential and the global temperature change potential showed that the methane equivalence coefficient relative to СО2 can be estimated as 4-11 rather than 25, according to existing assessments. The analysis revealed that methane turnover is a global natural process and anthropogenically caused methane release into the atmosphere has only a slight effect on the climate. The impact of the oil and gas sector is estimated at 0.1% of total global greenhouse gas emissions and 0.004% of the methane of the Russian gas sector.
