The biggest impact climate change will have on the poor will be through agriculture. Under a pessimistic "poverty" scenario with high climate change impacts, there could be more than 100 million additional people in poverty by 2030, largely due to changing crop yields and prices. Under an optimistic "prosperity" scenario, these effects are greatly reduced. Read more in the new "Shock Waves" report.
The World's CO2 emissions grew 4.9% in 2010
That's the 3rd largest annual increase since 1990 (early estimates of 2011 and 2012 emissions show further global increases since 2010, but not quite as large). Nationally, China, the United States, India, Russia and Japan continue to be the top 5 emitters. It's also notable that in 2010 South Korea surpassed Canada in 8th place, and South Africa fell out of the top 10 with an emissions drop of almost 3 percent.
