Of course, one has to ADD China's to the growing total and growing Concentration of Atmospheric CO2.

Even if emissions were capped at 1990 (1980, 1950, or even 1900) levels, CO2 concentration would continue growing.

Carbon dioxide passes symbolic mark
10 May 2013
Daily measurements of CO2 at a US government agency lab on Hawaii have topped 400 parts per million for the first time.
The station, which sits on the Mauna Loa volcano, feeds its numbers into a continuous record of the concentration of the gas stretching back to 1958.
The last time CO2 was regularly above 400ppm was 3-5 Million years ago - before modern humans existed.
Scientists say the climate back then was also considerably warmer than it is today.
Carbon dioxide is regarded as the most important of the manmade greenhouse gases blamed for raising the temperature on the planet over recent decades.
Human sources come principally from the burning of fossil fuels such as coal, oil and gas."..."
This is the May graph at co2now.org
June will show just over 400PPM.
Great for seeing the last 50-60 year damage as well.
