Document Summary

Lecture 1 notes global warming and the greenhouse effect. Earth"s at(cid:373)osphere is largely tra(cid:374)spare(cid:374)t to (cid:448)isi(cid:271)le radiation and uv radiation from the sun. Lecture 2 notes global warming and the greenhouse effect. Co2 is not often thought of as a pollutant because it is essentially non-toxic and is a natural component of air. Earth"s at(cid:373)osphere is largel(cid:455) tra(cid:374)spare(cid:374)t to (cid:448)isi(cid:271)le radiation and uv radiation from the sun. The radiatio(cid:374) is a(cid:271)sor(cid:271)ed at earth"s surfa(cid:272)e, a(cid:374)d this (cid:449)ar(cid:373)s the earth. Some of the radiation that hits the surface is reradiated back as infrared radiation (ir), which many atmospheric gases including co2 (primarily), methane and water vapour absorb and produce a (cid:449)ar(cid:373)i(cid:374)g effe(cid:272)t titled the (cid:862)gree(cid:374)house effe(cid:272)t(cid:863) The natural greenhouse effect is essential in maintaining the proper temperature on earth without it. Over the past 400 000 years, the carbon dioxide concentration in the atmosphere has varied between.
