-- Co2 released to the atmosphere through the burning of fossil fuels is cycled through the oceans based on a five year residence time, so that only about a quarter of the co2 in the atmosphere at any one time is from man.

Current attempts by national governments worldwide to control industrial CO2 emissions following the recommendations of the IPCC could be viewed within the scientific paradigm as the projection of a large scale experiment on the earth's climate system to validate the hypothesis that anthropogenic CO2 emissions through the burning of fossil fuels and land use changes (inter alia) are a major factor driving climate change.
