AOS 100 Homework #3 1) (a) Explain why an increased concentration of CO 2 (Carbon dioxide) in the atmosphere could lead to higher global temperature. An increased concentration of CO 2 will increase the temperature of Earth. Solar radiation that penetrates the atmosphere toward the surface of earth will warm up the temperature of earth. Consequently, earth, a black body, will emit its infra-red radiation; however, as we know that CO 2 is an excellent emitter and absorber of infra-red radiation, it will absorb most of infra-red radiation and keep them from leaving the atmosphere. Thus, as many CO 2 increases, earth atmosphere will act as a bar that keeps the temperature warmer. (b) One result of increased global temperatures would likely be more evaporation and therefore more H 2 0 (Water vapor) in the atmosphere. How might this further change the global temperature and why? It is known that H 2 0, CO 2 , and CH 4 are crucial greenhouse gases in the atmosphere of earth. If more evaporation takes place, then the number of H
