Methane is an inert gas that is odorless. When you "smell" methane you smell an additive from the gas industry. Methane leaking from gas wells does not have a smell nor is it in your neighborhood. The largest source of methane emissions is natural wetlands and agriculture. https://twitter.com/SenMarkey/status/1387132899418324995">https://twitter.com/SenMarkey...
Nearly 3 times more methane is released from natural sources and agriculture than from oil, gas, and coal combined. Methane represents 0.000001875% of the atmosphere and has a negligible impact on total warming since 1850.
