In this video I will explain what is the greenhouse effect on Earth. It is the warming of the atmosphere accomplished by the absorption of the Sun's energy by H2O, CO2, CH4, N2O, O3 (aka, greenhouse gases) and transferring that energy to the other molecules in the atmosphere (N2, O2) before it is lost (radiated to space).
