Greenhouse gas warming
30
Per capita CO 2 emissions are small in developing countries (metric tons of carbon dioxide)
31
Developed nations have altered the atmosphere most
32
Stabilizing CO 2 means steep emission cuts eventually
33
Success story: CFC production has fallen sharply
34
Backsliding: Halon production is rising again
