Solar radiation X passes through our atmosphere and heats the earths surface. The surface absorbes the energy and warmth (radiation Y) flows through the atmoshpere, while heating it. Greenhouse gases in the atmosphere adsorb radiation Y, thereby raising the temperature of the atmosphere.

Description:

Global warming is the trend of increasing temperatures on a global scale. The source of this heating is believed to be the greenhouse effect, which is the culmination of CO2 in the atmosphere acting as a warm blanket keeping the heat in.

Dynamics: The sun heats the earth's surface using its solar radiation. The heat coming from the surface can be seen as infrared radiation which under normal conditions can easily escape back again. However, large amounts of CO2 in the atmosphere prohibit the infrared heat-rays to escape quickly, causing global warming.
