I like the 'matter of fact' way that you put your arguments Nick. They are presented somewhat as a teacher would present 'facts' to a class of pupils. No matter how hard you try to represent the opposing views, using somewhat extreme examples from obscure websites, as a lunatic fringe, the fact remains that the majority of scientific opinion is on the side of global warming and over-population.
These are not my personal beliefs but, in the interest of balance, they most certainly should be given creedence.
As for AIDS being purposely introduced Pete, well........what can I say against such logic.......it's dumbfounding

I am always careful to give links, where possible, to the opinions, statements and data, to use the acronym IMHO (In My Humble Opinion), and to say "I believe something to be true". I don't believe I act like a school teacher. I hope not, anyway. :-/
As for the "majority of scientific opinion being on the side of global warming", I would contest that.
But even if there were a consensus, my views concur with those of Michael Crichton:
"Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results."(Address to Commonwealth Club - will dig out link upon request)
