We've seen this Essenhigh kook on alt.global-warming
before. Google his name on an archive of that
group. Note that he's a mechanical engineer, who
publishes in the op-ed pages of a chemical journal.
No one but Bonzo takes this crank seriously.

And trend of rising CO2 due to natural factors only.

IF carbon dioxide emissions from fossil fuels only stayed in the atmosphere a few years,
say five years, then there may not be quite the urgency currently associated with
anthropogenic global warming.

Indeed it might be argued that the problem of elevated levels of atmospheric carbon
dioxide could be easily reversed as soon as alternative fuel sources where found and/or
just before a tipping point was reached.

The general consensus, however, is not five years, but rather more in the range of 50 to
200 years.

But in a new technical paper to be published in the journal 'Energy and Fuels', Robert
Essenhigh from Ohio State University, throws doubt on this consensus.

Using the combustion/chemical-engineering Perfectly Stirred Reactor (PSR) mixing
structure, or 0-D Box, as the basis of a model for residence time in the atmosphere, he
explains that carbon dioxide emissions from fossil fuels are likely to have a residence
time of between 5 and 15 years.

He further concludes that the current trend of rising atmospheric carbon dioxide
concentrations is not from anthropogenic sources, but due to natural factors.
