"While I am writing this, exactly how do we know CO2 is a greenhouse gas? There isn’t a hell of a lot of it in the atmosphere - 0.036% of the global atmosphere - so how does this minuscule proportion affect the global temperature? And as human exhalation accounts for 38 billion tonnes of CO2, and animals probably the same again, what remedies do the warmers have in mind for this? Mass genocide? Oh Gosh, I forgot the plants. There are apparently 1877 billion tonnes of biomass, half of which is carbon. Virtually all of this is presumably expressing CO2 during the hours of darkness, and oxygen in daylight, due to photosynthesis. What’s the green answer to that? Cut down all the forests?"
