johnmorrissey – Your CAFE stats are wrong, your claim that more efficient cars and trucks do not significantly affect fuel usage is both profoundly ignorant and a manifestation that you are so deep into fringe ideology that you reject obvious facts.
Matthew M – By the way, human CO2 emissions are irrelevant to the climate and the supply of fossil fuel is essentially limitless (especially if we allow for the equivalent of $75/barrel and use nuclear power.)
1. You don’t know if man-caused CO2 emissions are irrelevant to the climate. You are making such a statement as an expression of your personal theology – not as someone examining the evidence objectively – which scientists and leaders involved in the question of AGW have different opinions and judgements on.
A. Evidence strongly points to AGW, and in their judgment it is a catastrophic problem.
B. Evidence shows a strong rise in CO2 directly attributable to mankinds activities and population explosion…which their models show a slight to moderate effect on climate.
C. Evidence is not conclusive one way or the other. It is too early to know…
D. Evidence shows a very slight role of man-made CO2 on climate, given other variables…but we should begin implimenting strategies to reduce both population and CO2 generating activities to equilibrium values.
2. the supply of fossil fuel is essentially limitless.
Sorry, but that is just a stupid assertion. The supply of anything on Earth is by definition, finite. In the case of scarce, valuable non-renewable resources like fossil fuels, rare minerals being depleted faster than reserves have been found despite quadrupling of prices – we can put a date on when supply becomes so limited that price rises high enough (or warfare replaces market forces) so that demand has to be driven down to meet dwindling supply.
