This article published in the journal Nature highlights the importance of systematic observation of greenhouse gases and atmospheric pollutants at the global level. This allows us to observe the oscillations of methane and other compounds in the atmosphere simultaneously and try to infer what causes them.  

This study demonstrates that the behaviour of methane, one of the most potent greenhouse gases, is complex and depends on multiple factors that condition its anthropogenic and natural emissions and sinks. Changes in these factors can result in a priori contradictory changes if the relationships between these factors are not considered.  

In this case, despite the reduction in anthropogenic methane emissions, concentrations increased in the atmosphere due to the decrease in air pollution during the covid-19 pandemic, which reduced the methane sink capacity of the atmosphere, and the increase in natural emissions from wetlands due to the exceptional temperatures in 2020.
