Eighteenth Question for President Biden

Mr. Biden, the Holocene Warming Optimum of 6,000 years ago was several degrees warmer than what we're experiencing today and the CO2 levels were only about 240 parts per million. How do you square this with the current climate change theory which claims that CO2 is the primary driver of the planet's temperature? And, please, do not give me the "appeal to authority" argument as that, Mr. President, has become exceedingly played.
