I like to ask climate change advocates who insist it's all being driven by CO2 how much CO2 does the earth's atmosphere contain and often they have no idea. Currently it's less than 400ppm and the earth has had periods where it's been much higher and global temps have been lower.

To take one factor like that out of context in a system so complex is ignorant at best and outright fraudulent for any real climate scientist.

It's just a way to extort money from humanity and implement draconian control policies.
