Ron - You are right to doubt humans' ability to work collectively to
come up with a solution, but surely you can't deny/doubt that human
activity can have deleterious effects?
There are many, many ways in which human activities have an effect on a
large scale - power stations causing deforestation through acid rain,
death of marine environments due to pollution/toxic wastes, changes to
mesoclimates through deforestation, loss of soils leading to land
degradation on the plains of the USA etc. If you accept that human
activities can affect micro/mesoclimates then surely you must accept
that the combined effects of these can have an effect on a wider
continental/global scale?

Hi Jim,
We humans are so, so arrogant in that we believe we can influence the
planet ... move continents, make it rain, hold back the sea, destroy the
earth with nuclear fission, divert comets and meteors. Hog wash? When we
finally develop the ability to create true peace on this earth and
banish wars and conflict to history, then, and only then will I even
start to believe that could potentially have the power to influence
nature. We will, as a species, and whether by act of nature or our own
stupidity, all be gone by then. We may harm ourselves, all become
sterile from the chemicals infiltrating our water and the smog, but
mother nature will soldier on oblivious of our existence.

Why don't our native Elm and Lime produce viable seed? Because out
current
climate is too cold! About 12 years ago in the New Forest a trial pit
was
dug into peat layers dated 10K years old, and they discovered
Liriodendron
pollen.
Personally I cannot believe that since the industrial revolution the
activities of humans have had no effect whatsoever, but as with many
debates
of this kind there is a tendency to exaggerate polarised opinions. The
"truth" is inevitably in between somewhere - but not necessarily in the
middle!

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.
ron.
