Document Summary

Air pollution: mexico city, mexico smog overtop of the city, pollution correlates with high population concentration. Greenhouse gases: water vapour (h2o, carbon dioxide (co2, methane (ch4, ozone (o2, nitrous oxide (n2) Temperature and carbon dioxide: when the concentration of greenhouse gases in the atmosphere changes, so does the temperature, more greenhouse gases, higher temp and vice versa, can tell this through data from ice core samples. Human-made sources of greenhouse gases: growth in productivity, technological advances and human population has resulted in the at(cid:373)osphere (cid:271)e(cid:272)o(cid:373)i(cid:374)g a (cid:858)du(cid:373)pi(cid:374)g grou(cid:374)d(cid:859) for polluta(cid:374)ts, whi(cid:272)h has aug(cid:373)e(cid:374)ted at(cid:373)ospheric change, humans have accelerated this process. Human-made sources of carbon dioxide: combustion of fossil fuels (industry and transportation) Enhanced greenhouse effect: drastic increases in concentrations a(cid:374)d rates of i(cid:374)(cid:272)rease i(cid:374) ghg(cid:859)s: this amount of carbon dioxide is so high because of the impact that humans have had.
