The model produces different jobs and
growth projections for a business - as - usual
scenario with no technology breakthroughs or major new policies, and then generates different outcomes by factoring in new policies such as a national clean energy standards such as proposed by President Obama; increases in corporate average fuel economy standards; tougher environmental controls on coal - fired power generators; extended investment and
production tax credits for clean energy sources and an expanded federal energy loan guarantee program.
David Rutledge, an engineering professor at the California Institute of Technology who studies world coal
production, said the IPCC's «business as usual»
scenario is unrealistic because it essentially assumes that
growth of fossil fuels like coal will continue apace, which is unlikely.
However — the statement that global hydrocarbon usage (and hence CO2
production) has continued to surge greater than the 20th Century average, and Hansens
scenario B was for less than 20th Century average in
growth of CO2 was correct.
As far as CO2
production goes, we have vastly exceeded the expectation of
scenario B (which does not include the crazy CFC
growth) in terms of CO2
production, and yet the ppm count in the atmosphere is slightly lower than what Hansen would have been expecting from capped
growth with flat consumption after 2000 (if I remember
