over the three years from 1979 to 1982 when co2 emissions were decreasing due to the rapid increase in the price of oil that drastically reduced consumption, there was no change in the rate of increase in atmospheric concentration of co2 proving that humans were not the primary source for the increase in concentration.'

greenhouse gas:183
between the period 1970 to 2004, greenhouse gas emissions (measured in co 2-equivalent) increased at an average rate of 1.6% per year, with co 2 emissions from the use of fossil fuels growing at a rate of 1.9% per year.
