methane is different than carbon monoxide, i am not i scientist and dont pretend to know what effects have on the environment . but i do know that millions of years of ecological balance is being severely exhausted by our over-consumption and pollution. just because one does not agree with the politics does not mean we should disregard natures exquisite balance because we dont want to change our ways. you cannot burn endless amounts of fossil fuels and think there will not be consequences even on a molecular level.
