A similar assessment.

CO2 increase from 1800 to 2001 was 89.5 ppmv (parts per million by volume). The atmospheric carbon dioxide level has now (through November, 2013) increased since 2001 by 26.18 ppmv (an amount equal to 29.2% of the increase that took place from 1800 to 2001) (1800, 281.6 ppmv; 2001, 371.13 ppmv; November, 2013, 397.31 ppmv).

The average global temperature trend since 2001 is flat (5 reporting agencies http://endofgw.blogspot.com/). Graphs through 2013 have been added..

That is the observation. No amount of spin can rationalize that the temperature increase to 2001 was caused by a CO2 increase of 89.5 ppmv but that 26.18 ppmv additional CO2 increase had no effect on the average global temperature trend after 2001.
