I have read the Douglass et al paper and it's conclusion is that we must use caution when using models to predict future climate change. I think that's nothing new and something we all probably agree with.
Good show, Melatonin; this round is yours.

I thought the whole Venus global warming discovery would finally make most people realise that CO2 is quite clearly a cause of global warming. Venus has average surface temperatures 3 times higher than would be expected, considering its distance from the sun. However its atmosphere is 96% Carbon dioxide, so the greenhouse effect is extreme to say the least. CO2 is not the only cause of global warming on earth, or indeed the most prominent cause, but it is one of the causes we can actually do something about, so I can't see why people have a problem with dealing with it. If it prevents catastrophe for a few extra years then surely it is worth it? Ask a terminal cancer patient if they would want an extremely expensive drug that would extent their life for a year and you will be surprised what lengths they would go to, just to get that extra year.

I never bought this whole global warming, it didn't make sense. When we talk about warming temparatues, - yes water vapour keeps temperatures near the sea warmer in winter and coller in summer - that is a REAL greenhouse gas and documented in every shcool geography book. I can't remember ever reading about CO2 doing something similar as a child.

Never said they were indiciative of falsehods, but that they are indicitive of thoeory and not science. They show that there are no answers. Just what I have been saying. We are using assumption to come to conclusions. If this could happen then the impact would be, so then lets spend $10 trillion over the next 10 years and tax people based on their carbon foot print. Please I pay enough in taxes.
