12 Because of long time delays for the carbon cycle, drastically different scenarios yield very similar results for a 20 year time horizon, but drastically different result for a 50 to 100 year time horizon.

13 Turning off all emissions (very unrealistic) will still leave atmospheric CO2 Levels at 350 ppm in the year 2110.

16 Global per capita emission have held steady for past 30 to 40 years. For the past 30 to 35 years emissions have been closely linked to population.

17 Global carbon emissions steady for first time since 1992 Drop in rich countries' emissions caused by recession in 2009 was nullified by steep increases from China and India

25 Indias carbon emission through 2004

26 2008 emission comparison per country Us, China and India account for 48 % of world wide emissions

27 2008 emission comparison per country Top 10 countries account for 67% of global emissions. However all other countries contribute significantly
