6. Carbon Monoxide Boosts O3 and CH4

-- part contents for background part 6
----- text -----
  While carbon monoxide (CO) is not itself a greenhouse gas, increased levels of CO lead to increased levels of both tropospheric ozone and methane.  This is because carbon monoxide removes hydroxyl radicals (OH) from the air that would otherwise be available to react with O3 and CH4, and thereby raising the levels of these two greenhouse gases. 
  While CO occurs naturally in the atmosphere, it has been estimated that most CO in the air is due to man's activities.  The combustion of fossil fuels is the largest source of carbon monoxide, with internal combustion engines in cars contributing the most.  The burning of forests and grasslands for agricultural purposes also creates large quantities of CO.  The CO molecule is also chemically reactive, and is thought to have an average lifetime in the atmosphere of about 4 months. ***
