It is pretty complicated, so I will give just the little that I know......O2 and nitrogen make up 99% of the atmosphere, but they have ZERO effect on earth heating. CO2 and water vapor make up most of the remaining 1%. And they are capable of absorbing HEAT.

"Big effect"? How big? Tell me ... how big (or how much) did man-made CO2 warm the earth last year?
