It is a high school lab experiment to watch CO2 absorb infrared and heat up.

There is no universe in which you can dig vast amounts of carbon, burn it, and not have things warm up. There are lots of hard questions but the fundamental fact that the globe has to warm is an unavoidable conclusion.

Yeah but your high school experiment has no feedback mechanisms, no oceans, water vapor, volcanos, solar cycles, plants, and so on. You’re also not putting in 0.04% CO2 vs 0.0395% CO2 and measuring anything meaningful because the scope and scale of the Earth’s atmosphere is unfathomably larger.

If you’ve ever owned a Fish Tank or taken High School Chemistry, you’d realize that even in the most simple environments things don’t always add up in a way that seems intuitive.
