The evidence I've seen shown temps and CO2 increase but that the CO2 follows the temps and not the other way around. Increased CO2 is good for the planet. It means a greener planet. It also means increased O2 levels.
Their alarms about sky high levels of CO2 are ridiculous. We are under 400 ppm. The lowest we have been was a little under 300 ppm. Any lower and we would all be dead. The planet has had levels above 8,000 ppm. That was the extreme high level. Normally we get to around 4,000 ppm. Those periods were also when life on this planet, including us, flourished the most. There is a reason commercial greenhouse farmers pump CO2 into their greenhouses and keep the levels above 2,000 ppm. And guess what...
It doesn't hurt the workers.
