The artificial neural networks (ANN) method they use is a form of sophisticated curve-fitting and extrapolation. They “forecast what temperatures would have been in the absence of human-emission of carbon dioxide – for the last hundred years.” “We figured that if we could apply the latest data mining techniques to mimic … Continue reading Evidence Inconsistent with CO2 Global Warming Hypothesis
