Carbon dioxide and other greenhouse gases collect in the atmosphere. They trap heat from the sun, so that it can't escape into space. This heats the earth up.
he said the definition. what else do you want. if you need more info, google it. we have more information rather than telling you our insights which appear always insufficient.

The greenhouse effect refers to the change in the steady state temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs and emits infrared radiation. A runaway greenhouse effect involving carbon dioxide and water vapor may have occurred on Venus. It is not possible that such an event will occur on Earth as a result of anthropogenic perturbations, but other potential runaway climate change effects involving Arctic methane release from permafrost have been identified.

The greenhouse effect is what keeps the earth warm. Eliminate it and the earth will totally freeze over. TOTALLY FREEZE OVER
The problem with Global Warming is not the greenhouse effect in total but the fact that human impact is skewing the greenhouse effect off of its normal equilibrium value.
We need a certain amount of CO2 in the atmosphere to keep the earth warm. Too little and you get an ice age, too much and you get melting and increased sea levels and unpredictable weather.

The greenhouse effect is the heating of the surface of a planet or moon due to the presence of an atmosphere containing gases that absorb and emit infrared radiation. Thus, greenhouse gases trap heat within the surface-troposphere system. This mechanism is fundamentally different from that of an actual greenhouse, which works by isolating warm air inside the structure so that heat is not lost by convection. The greenhouse effect was discovered by Joseph Fourier in 1824, first reliably experimented on by John Tyndall in 1858, and first reported quantitatively by Svante Arrhenius in 1896.
In the absence of the greenhouse effect and an atmosphere, the Earth's average surface temperature of 14 °C (57 °F) could be as low as −18 °C (−0.4 °F), the black body temperature of the Earth.Anthropogenic global warming (AGW), a recent warming of the Earth's lower atmosphere, is believed to be the result of an "enhanced greenhouse effect" mainly due to human-produced increases in atmospheric greenhouse gases.
