CO2 in 2009 was 387.35ppm - CO2NOW organisation. Need to get back to 350.

25/4/2010 In 2009, the average concentration for atmospheric CO2 (Mauna Loa Observatory) was 387.35 parts per million (ppm).In 2008, it was 385.57 ppm. 

Since the 1958 start of precise CO2 measurements in the atmosphere, the annual mean concentration of CO2 has only increased from one year to the next.   There have been no decreases in annual CO2 levels since direct instrument measurements began.  The following CO2 data provides a snapshot of the longest-running, high-precision instrument record for atmospheric CO2:
