The Intergovernmental Panel on Climate Change (IPCC), “In climate research and modelling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that long-term prediction of future climate states is not possible.” long-term prediction of future climate states is not possible The Intergovernmental Panel on Climate Change (IPCC), Third Assessment Report (2001), Section 14.2.2.2, page 774.

The Computer Climate Model Clockwork Fallacy Model forecasts are “based on well-known equations of conservation of momentum, mass and energy and the equation of state.” “Global climate models are based on the laws of physics; they make no assumption of climate constancy or inconstancy.”
