I'm sure many may have seen the recent BBC 2 documentary series - Earth
(power of the planet). Fascinating insight into the history of our
planet, including its fluctuating climate cycles over incomprehensible
periods of time.
Ron raised a valid point of view (IMO). Not that I'm suggesting we
ignore any human impact of course - like cutting down South American
rain forests to grow Soya, for bio fuel or feeding cattle (which produce
methane!).

Some interesting comments. Don't forget that we are talking the
short-term, minor, carbon cycle here. The largest amounts of carbon are
locked up in the long-term cycle through the sea and released back via
geological events. Humans are estimated to contribute 3% to the short
carbon cycle, into the atmosphere, which in turn contributes less than
1% of the carbon total ... so we are responsible for somewhere 0.03%?
Please bear in mind that the carbon we consume would end up back in the
atmosphere anyway. So many factors involved, including animals ...
methane!
I'm sorry, but I do not subscribe to the human, carbon, global warming
theorem ... its a natural process ... glaciations ... tectonic movement
etc.
