One of alarmists’ favorite lies is that “methane is 30 times worse than CO2”
This is complete BS. Methane’s absorption bands almost completely overlap with H2O, and methane concentrations in the atmosphere are very low. CH4 quickly oxidizes and disappears from the atmosphere, so there can never be a lot of methane in a warm atmosphere with a large concentration of O2.
Methane contributes almost nothing to Earth’s greenhouse effect.
