what are some equations involving carbon dioxide that have to do with global warming?

Question

i am writing a piece to explain what global warming is

Answer 1

The theory of carbon dioxide, is it traps heat from the sun, at earth level and keeps it from bouncing back into space.
That is why it is called a greenhouse has.
The more CO2 in the air, there is theoretically more heat trapped, ...hence that thought about global warming.

It is not a chemical action, it is a physical one.
