C. J. Campbell, like almost all peak-oil experts believes that global warming is a distraction because the end of oil will solve that problem and produce a better less "consumeristic society" after killing off a few billion people. Here's how Campbell puts it.
A decline in the supply of cheap oil-based energy will have an unavoidable
and far-reaching impact on the economic prosperity of the World. It may on
the other hand have a positive impact on the environment generally. For
example, climate change concerns
might evaporate. —C. J.
Campbell, 2003.
