New paper explains inherent flaws of computer models predicting future climate change
London, 21 February: Claims that the planet is threatened by man-made global warming are based on science that is based on inadequate computer modelling. That is the conclusion of a new briefing paper published today by the Global Warming Policy Foundation (GWPF).
The report’s author, eminent American climatologist Professor Judith Curry, explains that climate alarm depends on highly complex computer simulations of the Earth’s climate.
But although scientists have expended decades of effort developing them, these simulations still have to be “tuned” to get them to match the real climate. This makes them essentially useless for trying to find out what is causing changes in the climate and unreliable for making predictions about what will happen in the future.
Professor Curry said: “It’s not just the fact that climate simulations are tuned that is problematic. It may well be that it is impossible to make long-term predictions about the climate – it’s a chaotic system after all. If that’s the case, then we are probably trying to redesign the global economy for nothing”.
Prof Curry recently announced that she was abandoning academic life due to the attacks on her research and the “craziness” of the climate debate.
