Alright, I'm going to 2nd the recommendation for you to visit the climate change thread that has already thrashed through this dozens of times over. You can get counterpoints to any position you hold in there.
Again, you can't start with a conclusion and work your way backwards to what we should be doing. There's no existential threat in evidence.
Here's the geologic timeline of CO2 concentration and temperature. Most of earth's history has been spent with CO2 concentration above 1000 ppm and temperatures at least 5 degrees warmer. Life flourished.
Below 180 ppm CO2, photosynthesis struggles. Plant life thrives somewhere around 1000 ppm. We're at 400. We're about as cold as earth has experienced and about as low of CO2 concentration.
Through all these enormous swings, the most devastating event was an asteroid.
