  1. The report justifies its findings by mentioning climate change 67 times, while pointing at the output of provably flawed climate simulations as "evidence". Climate simulations cannot be accurately run on computer systems because the climate system is chaotic and computers use discrete mathematics, even their floating point numbers are really just a form of approximation. Only a simulation using real numbers, i.e. true pure symbolic computation, can have a hope of approximating reality. This is a fundamental aspect of mathematics itself, and even with a full set of inputs and relevant physics the model will still diverge over time. It is delusional to believe that mathematics and science can predict the future state of natural systems, the current simulations are not even computationally asymmetrical, they can't be run backward from today to generate known past data from a century ago. Some recent work on using neural networks claimed to be better (but how can that be if current systems are accurate? hmmm...) however the output of those neural networks simply produce chaotic data with the same fractal dimensions as recorded data would without actually predicting it exactly, i.e. it could mimic the texture of the data but not give you an accurate snapshot of the real data for some point in the future. But I can give you a much simpler and pragmatic proof that the CSIRO people cannot predict the future, they would be billionaires if they could, because the mathematics is no more complex for a climate system than it is for an economic system, i.e. the stock market.
