claim: When CO2 emissions are compared directly to CO2 levels, there is a strong correlation in the long term trends.
evidence: However, the Stern report, like many other reports, notes the past correlation between CO 2 emissions and economic growth and then extrapolates using a business as usual scenario to predict GDP growth and hence CO 2 levels, concluding that : Increasing scarcity of fossil fuels alone will not stop emissions growth in time.
