"What proof do you have that humans are _causing_ the climate to change, a climate which has been changing ever since the formation of the Earth 4.5 billion years ago? And what proof do you have that homo sapiens - who have only been on this planet for roughly 200 thousand years, of which have only been embarking in Industry for around 200 of those - can have any effect whatsoever in somehow stopping the climate from changing? Lastly, what definitive proof is there that the trace gas CO2, comprising of 0.04% of the Earth's atmosphere - of which humans are respnsible for a mere 0.01% of that - is the primary temperature control knob of this planet?"

The CO2/CAGW/Climate Change alarmism Emperor has no clothes!
