Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

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.]
