evidence: Applying statistical models (such as ARIMA or Hurst–Kolmogorov) to the past temperature data can generate a prediction for the future, but the confidence limits (95%) are so wide that the predictions are useless. And this approach cannot say that CO2 is causing the change. Thus, the climate models that predict a temperature response to CO2 have to be deterministic; that is, they assume that the inputs will determine the temperature. Hence the assertion based on these models that CO2 causes global warming is circular reasoning. Worse, even as recently as a decade ago climate models could not deal with factors like cloud cover. Computers are getting faster, and climate models are getting more sophisticated, but significant areas of the climate are still beyond our modelling reach. [...] The claim that 97% of scientists agree that human-generated CO2 will cause catastrophic warming to planet earth is fake news. Even if it were accurate, it would not prove that it is correct. It is the fallacious ‘argument from consensus’. As Michael Crichton said, "Consensus is the business of politics. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period." [...] In the USA, the Global Warming Petition Project has garnered the signatures of some 31,500 scientists resident in the USA alone, including over 9,000 with PhDs, who dispute the claim that CO2 will cause serious problems.28 This alone casts serious doubt on the 97% figure.
