The distortion of science for ideological purposes has a long history, and the results are generally ugly.
MAINSTREAM MEDIA INNUMERACY
My attention was drawn to the latest media reporting that CO2 has increased 2.5% per year since 2000 according to the Global Carbon Project reported here
. The source document is of two pages with lots of pretty coloured graphics (presumably on the basis that pictures are equivalent to a thousand words) and available here
Now they state in Policy Document 5 "That the growth rate of atmospheric CO2 was 2.05ppm per year,.." (page 1).
Express this as a percentage we calculate (2.05/1,000,000)x100 = 0.000205% per year.
Or should they have said (2.05/380)x100 = 0.54% per year?
Either way rather much smaller than 2.5% per year isn't it.Wikipedia
states that according to NOAA 97% of atmospheric CO2 is created from natural sources leaving 3% to human activities.
And As of 2006
, the earth's atmosphere
is about 0.038% by volume (381 µL/L or ppmv
) or 0.057% by weight CO2.
3% of 381 ppmv = 11.43 ppmv which is the human contribution
if each year an extra 2.05 ppmv of CO2 is added to atmospheric CO2, then the anthropogenic
component is 3% of 2.05, or 0.06 ppmv by definition.PER YEAR THE ANTHROPOGENIC CONTRIBUTION TO CO2 EMISSIONS IS 0.06ppmv or0.00000615% of CO2 per year.Each year we therefore seem to add 0.06 ppmv to 11.43 = 11.49 ppmvThe earth, all by itself, adds, at the current interpreted rate, 1.99 ppmv per year to CO2 levels in the atmosphere.
Figure it out!
HUMANS - 0.06ppmv CO2 per year
GAIA - 1.99ppmv CO2 per year
