The UN IPCC Third Assessment Report (AR3) was issued in year 2001 more than a decade after the 1988 hearing. That report finally acknowledged that it is not possible to develop climate models that can accurately model global climate and provide future climate predictions.
Specifically, the report in Section 184.108.40.206 noted:
“In sum, a strategy must recognize what is possible. In climate research and modeling, we should recognize 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 generation of ensembles model solutions.”
