Pump, Pump, Pump Up the Volume!

All CO2 Stats are Shooting Up!

Up goes the annual mean growth rate of atmospheric CO2 to 2.2 ppm for 2007.

• Growth rate for 2006 : 1.8 ppm
• Average rate for the period 2000-2007 : 2.0 ppm per year
• Annual mean growth rate average for 1977-2007 :  1.5 ppm per year
• Atmospheric CO2 concentration (2007) : 383 ppm  (37% higher than the preindustrial revolution levels of about 280 ppm (1750)
• Current concentration of atmospheric CO2 is the highest level probably in the last 20 million years
• Anthropogenic CO2 emissions have been growing about four times faster since 2000 than during the previous decade
• Emissions from the combustion of fossil fuel and land use change almost reached the mark of 10 billion tons of carbon in 2007
• Anthropogenic CO2 emissions are growing x4 faster since 2000 than during the previous decade, exceeding the worst case emission scenario of IPCC
• These changes imply a more critical impact on climate and sooner than expected

[ppm: parts per million]

Note: Based on FEWW calculations, the anthropogenic CO2 Emissions for 2007 almost reached 10.38 PgC.

Emissions increased from 6.2 PgC per year in 1990 to 8.5 PgC in 2007, a 38% increase from the Kyoto reference year 1990. The growth rate of emissions was 3.5% per year for the period of 2000-2007, an almost four fold increase from 0.9% per year in 1990-1999. (Source: Carbon Budget 2007 – Global Carbon Project).

[PgC: Petagrams of carbon. To convert to CO2 million metric tons, MMT, divide C figure by 12 and multiply by 44; e.g., 1PgC  is the equivalent of 3,666.67 MMT of CO2.]
