Skeptoid – like a skeptic but not quite

Here’s a new sign of the times.

Almost no one has gone from skeptic to believer on global warming. The conversion flow is nearly all one-way traffic. But on the Skeptoid site, author Craig Good is a “convert” of a sort, and I have to give him credit for writing the most sensible advice yet for believers of man-made global warming (see below).

But before anyone gets too excited, the two key questions here are: how much of a skeptic was he, and what did it take to change his mind? Answer, not much and not much.

This is not a big believer-awakening-moment of the Mark Lynas type, or another Judith Curry sort of conversion. Both of those were active, involved and outspoken in the climate debate.  Craig Good’s entire skeptical position can be summed up in a few paragraphs, so yes, he qualifies as a skeptic, of the gut-hunch-it’s-wrong-but-haven’t-read-a-single-skeptical-paper-type skeptic.

If there are grades of skeptic from 1 to 10, he was only a 2.

So here’s the flash of insight, that’s never been seen before from alarmist circles

This is great stuff (if blindingly obvious):

How John Cook unskeptically believes in a hotspot (that thermometers can’t find)

John Cook might be skeptical about skeptics, but when it comes to government funded committee reports, not so much.

The author of “skeptical science” has finally decided to try to point out things he thinks are flaws in The Skeptics Handbook. Instead, he misquotes me, shies away from actually displaying the damning graphs I use, gets a bit confused about the difference between a law and a measurement, unwittingly disagrees with his own heroes, and misunderstands the climate models he bases his faith on. Not so “skeptical” eh John? He’s put together a page of half-truths and sloppy errors and only took 21 months to do it. Watch how I use direct quotes from him, the same references, and the same graphs, and trump each point he tries to make. His unskeptical faith in a theory means he accepts some bizarre caveats while trying to whitewash the empirical findings.

In the end, John Cook trusts the scientists who collect grants funded by the fear-of-a-crisis and who want more of his money, but he’s skeptical of unfunded scientists who ask him to look at the evidence and tell him to keep his own cash.

These two graphs are not the same [...]
