(Un)Skeptical Science uses unmeasureable fudge factors

A comment from Tel late last year was so surgically cutting, it’s worthy of it’s own post.  Un-Skeptical Science was trying to explain why climate sensitivity is high. The post includes formula’s and fancy graphs, and looks authoritative — yet underlying everything are errors of reasoning that nullify all the points that rest upon them. Things like assumptions about linearity (which means more or less, they make the mistake of assuming that all forcings and feedbacks operate at similar ratios and strengths when the planet is an iceball as they do when Earth hits a rare warm phase). An unmeasureable variable is the telltale signature of a fudge-factor. It is what you make of it. Fits better in a course analyzing postmodernistic intertexuality of Swahili neo-linguists.

Guest Post by Tel

This “Skeptical Science” post is an excellent choice to show how little credibility there is in the whole feedback house of cards:

It’s important to note that the surface temperature change is proportional to the sensitivity and radiative forcing (in W m-2), regardless of the source of the energy imbalance. The climate sensitivity to different radiative forcings differs depending on the efficacy of the forcing, but the climate is not [...]

Supplement: Our Email exchange ……Ref: Skeptico on “Global Warming Denial”

What’s the most embarrassing thing that could happen to a skeptic? Could it be worse than being exposed for believing anything and everything a government committee (the IPCC) tells them?

“Science without debate is like business without competition and a trial without a defense. It’s a sham.”

Unfortunately some of the loudest skeptics are the part-time ones. They busy themselves ‘catching out astrologers’, but then suspend all their usual rules of logic to defend the largest scientific scam in history. Ironically, at the same time as the scammers plot to suck billions from citizens, pretenders like Skeptico arm themselves to the teeth to, wait for it… fight for “authority”.  (He actually does this—the unthinkable—he claims that argument by authority is legitimate in science. Holy-Cringeoli! Let’s bow to the bureaucrats.)

Here Skeptico responds to my emails by publicly trying to justify his belief in the AGW theory. In response, he steadily exposes himself for having faith, trust, and poor reasoning skills, he proves to be a ‘denier’ (of the need for empirical evidence), a name caller, as well as patronizing, and totally unaware of his religious faith to boot. All that, and [...]
