'In climate research and modelling... the long-term prediction of future climate states is not possible.' - That's from the IPCC's 2001 report

'In sum, a strategy must recognise what is possible. In climate research and modelling, we should recognise that we are dealing with a coupled non-linear chaotic system, and therefore that the long-term prediction of future climate states is not possible. The most we can expect to achieve is the prediction of the probability distribution of the system�s future possible states by the generation of ensembles of model solutions. This reduces climate change to the discernment of significant differences in the statistics of such ensembles.'

Oddly, this extract from the 2001 IPCC report went unreported by the warmist fanatics at the BBC.
