text: Pearce also tries to suggest that forecasting climate change is like forecasting the seasons i.e., easy. Unfortunately, Edward Lorenz proved that claim to be false very nearly half a century ago, in the landmark paper in a climatological journal that founded chaos theory. Lorenz demonstrated that unless we knew the values of the millions of parameters that define the climate to a precision that is not and can never be in practice attainable the long-range prediction of climatic behavior would be impossible by any method. Yet the UNs case for climate alarm is based almost exclusively on the output of models that have been demonstrated, time and again, to fail. Not one of the models on which the UN relies, for instance, had predicted that there would be 15 years without any statistically-significant global warming the years 1995-2009 inclusive.
