Carbon dioxide (CO2) is the chief greenhouse gas that results from human activities and causes global warming and climate change. To see whether enough is being done at the moment to solve these global problems, there is no single indicator as complete and current as the monthly updates for atmospheric CO2 from the concentrations of CO2 in the atmosphere are increasing at an accelerating rate (http://www.co2now.org/Current-CO2/CO2-Trend/acceleration-of-atmospheric-co2.html) from decade to decade. accelerating from decade to decade. The latest atmospheric CO2 data is consistent with a continuation of this long-standing trend. What level is safe? The upper safety limit for atmospheric CO2 is 350 parts per million (ppm). Atmospheric CO2 levels have stayed higher than 350 ppm since early 1988.

Measurements are made and reported independently by two scientific institutions: Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA). Monthly data is posted below.

The 2010 average is 389.78 ppm. For the past decade (2002-2011) the average annual increase is 2.07 ppm per year. The average for the prior decade (1992-2001) is 1.6 ppm per year. Annual data (ftp://ftp.cmdl.noaa.gov/ccg/co2/trends/co2_annmean_mlo.txt) for 2011 was first posted January 5, 2012, by the National Oceanic and Atmospheric Administration (NOAA) in the United States. Since the 1958 start of precision CO2 measurements in the atmosphere, the annual mean concentration of CO2 has only increased from one year to the next. The CO2 data below (http://co2now.org/Current-CO2/CO2-Now/annual-co2.html) provide a simple view of the annual trend.
