Methane. Otherwise known as the main component of natural gas.
Mankind’s contribution to methane production is less than .1 of 1%...There is NOTHING that man can do to eliminate it (and why would you want to?) The 3 ‘Scientists’ in the movie “In like Flint” had a better idea of climate control than these a**holes who call themselves ‘scientists’, when what they really are: “Acquirers of Free Grant Money from Rich Embeciles”..AFGFRE for folks who like acronyms..
