The Butterfly Effect.
Measurement errors and modeling errors get amplified over time to the point that predictions are impossible.
Even if the measurements are near perfect and the models nearly exact, there are still errors.
This is the biggest lie of all. The "know all" gods in scientific academia are being dishonest.
Oh, and the Navier Stokes equations, the ones that describe the nonlinear fluid flow of atmosphere with changes in temperature and density-
They also describe the fluid flow of the Sun, with another set of non-linearities and uncertainties.
The glow-ball warming predictions are just one level of hoax on top of another.
