Rapid rise in methane emissions in 10 years surprises scientists ( Haim - did the feedback loop started?) Methane warms planet 20 times as much as similar CO2 volumes but lack of monitoring means scientists can’t be sure of sources This doesn't make logical sense, we have a "lack of monitoring" combined with a "rapid rise". How do they know it's rising rapidly if it's not (or lighly) monitored? And if methane quantity is actually that bad, why not capture and use the energy in methane, especially in places like barns where it's at least partly contained already?

Well, doing a bit of googling, I came up with an EPA report showing a decrease in Methane emissions over the last 25 years in the US: "Methane emissions in the United States decreased by 16 percent between 1990 and 2015. During this time period, emissions increased from sources associated with agricultural activities, while emissions decreased from sources associated with landfills, coal mining, and the exploration through distribution of natural gas and petroleum products." So is the worldwide CH4 level increasing? I guess so from the report you posted. CH4 is eventually cleared from the atmosphere by natural processes -- much faster than CO2. Perhaps we are adding more CH4 faster than it's being cleared. I wonder how other countries are doing. At least, in the US, reduction in emissions is a step in the right direction. It's generally hard, in a politicized subject like greenhouse gas and climate change, to get a reliable handle on what is really happening -- although one would think that the percentage in the atmosphere would be something that can be reliably measured.
