Since you seem to take my comments absolutely literally I think it is not reasonable to take exception if I respond in kind. And I never jump at a chance to be condescending; they occur so frequently I only need to stroll around.
But I realise you do have a point; my statement; "nothing can be proven in science"? is not totally accurate and I did contradict myself when I said that experiments could prove a hypothesis wrong. This is a proof of a disproof I suppose. Somewhat like Aristotle's (or Plato's, I forget which) all men are liars statement.
By the way fizzy I take as a compliment that the only things you have taken exception to (so far) in my 'history' are two points which do not appreciably detract from my message that climate change has been and is occurring and that ascribing it solely to anthropogenic greenhouses gases is not completely accurate. Keep trying, you are still amusing.
