Methane released in the atmosphere contributes much more to climate change than CO2.
Methane makes up less than 0.000002 mole fraction of the atmosphere. If everyone in Camp Nou last night were a molecule of the atmosphere, odds are that none of them would be methane.
All of the minimal absorption bands of methane are completely overlapped by water vapor. Methane has almost no effect on the Earth’s radiative energy balance. Friedman is an idiot. He has no idea what he is talking about.
