claim: When CO2 emissions are compared directly to CO2 levels, there is a strong correlation in the long term trends.
evidence: The sharp acceleration in CO 2 emissions since 2000 to more than a 3% increase per year ( more than 2 ppm per year ) from 1.1% per year during the 1990s is attributable to the lapse of formerly declining trends in carbon intensity of both developing and developed nations.
