Her point is not science and not mathematics. Weather may be unpredictable due to too many variables, as predicted by chaos theory, but climate, which is averages over large areas and works on a decadal time scale, averages out the small variables and is amenable to prediction and modeling. That's why when we see a La Nina or El Nino forming in the Pacific in January we can predict the climate trends for July in North America. That's also why we can see a steady rise in global atmospheric CO2 levels and predict a warmer and therefore more chaotic climate into the future. Her theory of inconveniently observable climate shifts becomes 'weather' because it suits your bias. She is in fact talking about La Nina and El Nino oscellations. And for you to say previously that her theory only predicts backwards is another silly construct by you. The IPCC theory gathers data from the past and tries to extrapolate it forward. The data in climatology is from the recent and distant past of necessity. Dr Currey's position seems to be that the data is being analyzed through a linear fashion unjustified by the reality of the chaotic dynamics of climate. And yet there is such a cascade of persuasion that the nations of the world are prepared to institute action upon this faulty analysis as if it were handed down from a burning bush. Newton's theory of gravity was modified by General Relativity and GR may be modified by future analysis. There is no theory that is sancrosanct in Science. The world would be better preparing for the possibility of future warming, which is questionable, than wasting resources in a futile attempt to hold Nature back. In the meantime if we are able to reduce pollution of ground water and the seas by petroleum and natural gas then all the better by me. Then her theory should predict the next 'shift' which it doesn't. Or what the climate will be like after the next shift? Science is by definition predictive. Her hypothesis, at this time at least, is not predictive and is therefore not science.
