Thanks for taking the time and trouble to post an informed and considered
reply. I can take on board most of what you say. As I said in my previous
post, I too am unconvinced about the ability of man to significantly
affect
the levels of CO2 prevalent in the atmosphere. I read somewhere a while
back, that in fact water vapour in the atmosphere has a much greater
greenhouse effect than CO2. Did you catch the excellent CH4 documentary
"The
Great Global Warming Swindle" a while back? Very thought provoking. If you
didn't, I believe it is available to view on YouTube.

ISTR it was fairly comprehensively debunked

Concerted and furious attempts were made to debunk it. They were not very
sucessful. Everyone interested in this subject should read Lord Lawson's
excellent little book 'An Appeal to Reason'. This examines in minute detail
the economics of the various possible courses of action that mankind can
take regarding alleged global warming, and concludes. . . well, go on, buy
the book! It's only six quid.
