The greenhouse effect is when the sun radiates solar energy on earth. The higher amount of energy is radiated back into space. (1) Greenhouse gases in the atmosphere contribute to global warming by adsorption and reflection of atmospheric and solar energy. (1) The greenhouse effect is the cause for our warming temps. Two factors that affect the greenhouse effect are the shape of Earth's orbit and its tilt with regard to the Sun. (2) Both of these change slowly over the years, when they do they alter the effects of the greenhouse.(2)
