Even then, it's worse by weight over most timescales. https://en.wikipedia.org/wiki/Global_warming_potential: "In the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, methane has a lifetime of 12.4 years and with climate-carbon feedbacks a global warming potential of 86 over 20 years and 34 over 100 years in response to emissions." (CO2, being the baseline, has a GWP of 1.) |
