Understand the basic global energy budget: What happens to the solar energy as it hits the Earth? What happens to the heat that is re-radiated as infrared radiation?
Some of the radiation is absorbed by clouds and some of it is bounced back into space. The infrared radiation is captured in the atmosphere and that generates more heat and increases global warming.
