From Media Summary Highlights:

The annual growth rate of atmospheric CO2 was 2.36±0.09 ppm in 2010 (ppm = parts per million), one of the largest growth rates in the past decade. The average for the decade 2000-2009 was 1.9±0.1 ppm per year, 1.5±0.1 ppm for the decade 1990-1999, and 1.6±0.1 for the decade 1980-1989. The 2010 increase brought the atmospheric CO2 concentration to 389.6 ppm, 39% above the concentration at the start of the Industrial Revolution (about 278 ppm in 1750). The present concentration is the highest during at least the last 800,000 years.
