Here is the entire paragraph you keep quoting....in laymen's terms Li...its recognising the need to improve methods as well as outline better ways to present findings....its called science Li....not what your cherrypicking bs quite says...
do you know anything about acceleration yet?
Improve methods to quantify uncertainties of climate projections and scenarios, including development and exploration of long-term ensemble simulations using complex models. The climate system is a coupled non-linear chaotic system, and therefore the long-term prediction of future climate states is not possible. Rather the focus must be upon the prediction of the probability distribution of the system�s future possible states by the generation of ensembles of model solutions. Addressing adequately the statistical nature of climate is computationally intensive and requires the application of new methods of model diagnosis, but such statistical information is essential.
