There are many, many flaws with this whole notion of catastrophic anthropogenic global warming, but one of the most obvious is that the hypotheses–the models–are treated as DATA. That is a circle. That is not how science works.
The only reason this whole farce has been able to be continued–admittedly at great cost and considerable effort–is because the time horizons in play prevent the immediate and incontrovertible empirical refutation of their models. They have been, and continue to be, wrong, but they keep telling us, decade after decade, that the final tweak is just around the corner. There is no historical basis either to believer this now, or to trust them in the slightest at any point in the future, absent actual corroboration of their models. They lie. That’s what liars do.
