Nature responsible for large chunks of CO2 which we're only discovering lately? And what ratio is nature's CO2 emission to man's? Oh, we don't know yet? But haven't we already come to the conclusion that it's man's CO2 that's ruining the atmosphere, and man who must change his ways, at gunpoint if necessary? Isn't anyone who questions this, even with evidence, as out of touch and deserving of ostracism as a holocaust denier? I'm confused. We'd better put a stop to all this discovery of new natural CO2 sources, or we'll derail an opinion train as it gains peak momentum.
