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!

400 PPM

Weekly average CO2 at Mauna Loa could hit 400ppm by May 2013: FIRE-EARTH

FIRE-EARTH projections show, based on the data provided by Mauna Loa Observatory, the average CO2 at Mauna Loa could climb to 400ppm in the next 6 weeks.

Up-to-date weekly average CO2 at Mauna Loa

  • Week of March 24, 2013:     397.92 ppm
  • Weekly value from 1 year ago:     395.30 ppm
  • Weekly value from 10 years ago:     377.06 ppm

CO2 Daily and Weekly Means at Mauna Loa [April 2012 – March 2013.]  The weekly mean (red bar) is simply the average of all days in the week for which a background value could be defined. The average standard deviation of day to day variability, calculated as the difference from the appropriate weekly mean, equals 0.38 ppm for the entire record. As a visual aid, the blue lines present monthly means of background data as they are presented under Recent Monthly CO2 at Mauna Loa. [Source: ESRL/NOAA]  

Recent Mauna Loa CO2

  • February 2013:     396.80 ppm
  • February 2012:     393.54 ppm

  • January 2012:     392.44 ppm

Time history of atmospheric carbon dioxide from 800,000 years ago until January, 2012.

long-lived ghg
Global average abundances of the major, well-mixed, long-lived greenhouse gases – carbon dioxide, methane, nitrous oxide, CFC-12 and CFC-11 – from the NOAA global air sampling network are plotted since the beginning of 1979. These gases account for about 96% of the direct radiative forcing by long-lived greenhouse gases since 1750. The remaining 4% is contributed by an assortment of 15 minor halogenated gases (see text). Methane data before 1983 are annual averages from Etheridge et al. (1998), adjusted to the NOAA calibration scale [Dlugokencky et al., 2005].  Source: ESRL/NOAA.  Click on image to view larger image.
