The greenhouse effect refers to the change in the thermal equilibrium temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs and emits infrared radiation

 Anthropogenic global warming (AGW), a recent warming of the Earth’s lower atmosphere as evidenced by the global mean temperature variance trend, is believed to be the result of an "enhanced greenhouse effect" mainly due to human-produced increased concentrations of greenhouse gases in the atmosphere and changes in the use of land.
