I definitely agree that there are alarmists who politicize the issue to no end, and want to use to gain power.

But afaik the CO2 questions are extremely well-studied: 1) that atmospheric CO2 levels have steadily risen for a long time 2) that we put a lot of CO2 into the atmosphere, and into the oceans by extension, through dissolution. 3) that CO2 traps radiation emitted by the Earth, which has a heating effect on the lower atmosphere and Earth surface. Which of these three do you disagree with?
