Second, most of the alleged warming almost certainly just comes from data tampering by NOAA. NOAA "models" an increasing number of its stations (lately around 40%). On those stations, it fabricates data according to a model, and applies a varying fudge factor that cools the past and warms the present in a way that assumes the CO2 hypothesis.

Besides being secret and likely buggy, any simulation of the climate necessarily incomplete, i.e. it omits quite a lot of phenomena. Complex systems are fundamentally non-amenable to simulation, but in this case, the results of the "simulation" are garbage squared, because they're "simulations" of some system that doesn't even exist.
This is the kind of stuff being passed off as science these days.
