Al Gore even made some hardened liberal journalists sit up and question when in 2007 he told a joint session of the House Energy Committee and The Senate Environment Committee that the climate debate was over, “the science was settled”. The journalists knew, as any moderately informed person does, that science is never settled. But, what does “settled” mean in this context? The most reasonable definition is linked directly to a simple definition of science, namely the ability to predict. If you can’t predict then your science is wrong, as Feynman and others made clear. Failed predictions prove that the science isn’t settled. Gore and the supporters of the Intergovernmental Panel on Climate Change (IPCC) version of anthropogenic global warming (AGW) claim the science is settled, but their climate predictions (projections) are consistently wrong. The problem is wider because the weather predictions of national weather agencies who are, through the World Meteorological Organization (WMO) the IPCC, don’t work either. The climate is the average weather, which raises the question; when does weather become climate? Since climate is an average of the weather, the average temperature for a 24-hour period is the climate of the day. If the science is settled, then the weather forecasts should also be accurate, but they are still increasingly unreliable beyond 48 hours. One use of the millions of weather data points created for my doctoral thesis was by a statistician, Alexander Basilevsky. He was working on Markov Chains defined as follows:
