A. s.a. p which supporting paragraph would best contribute to the following thesis statement? the leading pollutants contributing to global warming are carbon dioxide, methane, and nitrous oxide. a) carbon dioxide is a gas released into the air by the burning of fossil fuels. co2 traps the heat and creates a "greenhouse effect" on the earth. in the united states transportation and the burning of fossil fuels to make electricity are the biggest factors to the co2 pollution. b) global warming is causing dramatic weather patterns. glaciers are melting and the world is experiencing more drought and extreme weather. it is also cause of extinction of several endangered species. these are just a few of the negative effects of global warming. c) i used to drive an hour to and from work every day. when i learned about global warming and the negative effects of carbon dioxide pollution, i decided to start carpooling. now i ride to work with four co-workers. we all take turns driving, and together we're are releasing 1/4 of the amounts of pollution into the atmosphere each week. most large cities offer "ride share" programs and incentives for participating. d) according to wikipedia, "methane is a chemical compound with the chemical formula ch4 (one atom off carbon and four atoms of hydrogen. the relative abundance of methane on earth makes it an attractive fuel, though capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure. natural methane is found both below ground and under the sea floor."
