Close enuf for Roman Numerals. Congrats; You win a lollypop.


2.1 ppm/year increase
total is 400 ppm.

that's about 0.5%

The 2013 average annual concentration of CO2 in the atmosphere (Mauna Loa Observatory) is 396.48 parts per million (ppm). The 2012 average is 393.82 ppm.

For the past decade (2004-2013) the average annual increase is 2.1 ppm per year. The average for the prior decade (1994-2003) is 1.9 ppm per year. Annual data for 2012 was first posted January 9, 2014, by NOAA-ESRL in the United States.
