The problem is that there is apparently no absolute consensus in the scientific community. The real concern is that the IPCC report has become the focus of political agendas, as shown by this film:

The film is worth getting hold of, if only to understand the arguements against C02 warming. From memory it does not mention that the reason it was so much hotter in the time of the dinos was that plants hadn't sucked all the CO2 up. Make up your own mind.
The real problem here is there has not been done a nice simple high school style experiment which removes (or otherwise) any doubt. We need Adam Hart-Davis to the rescue! Any BBC chartered heli pilots?
My own view is that if CO2 debate leads to an efficiency drive, than that is not a such a bad thing. CO2 may be pressurised back into the gound, where it will remain as a sublimed solid. Hovever i would not be suprised if already infrastructure efficient helicopters began R&D on blade twist for reduced fuel burn. Not such a bad outcome.
Maybe all that CO2 R&D money should be seen as an opportunity.
