It's a fraud, a hoax, a scam, some sort of mass delusion fueled by people whose only relief from their own delusions is that they understand how to advance their own selfish interests at the expense of others.
Earth's temperatures vary all the time, so the CO2 levels. What little they are able to get out of the data, the rise in CO2 follows not leads temperature rises. It's not a cause.
