Problem is not the term "natural gas", but near mystic reverence of all things "natural". "Natural" is not necessarily better. A disaster that is a "natural" disaster is not preferable. Malnutrition, Smallpox, Polio, Cancer, Getting eaten by a Lion- these are also "natural".
Can we stop putting “natural” in front of “gas”? One of the most successful greenwashing efforts of all time. We don’t call it “natural wind” or “natural sun” - or “natural coal”, for that matter. The nature of gas is that it’s a fossil fuel whose combustion causes climate change
