The proper analogy would be that "surgeons" would recommend an operation --- because --- well, that's what Surgeons do.
A good doctor would say take two aspirin and call me in the morning.
For a damn theory based entirely on computer models that are not even close to accurate on "predicting" past trends, that ignore major variables because they are more complex that we can model or compute, on a warming trend that isn't even a century old, using proxy data for measurements older than 200 years, is the equivalent of allowing someone to dig into your skull 30 seconds after your headache started because he told you that you will die if he doesn't. It's junk science at it's worst.
And you notice how this book huckster dismisses climate scientists who don't buy on to his religion? (Tools of big polluters). Yet this guy knows squat about climate science --- he's a freak'n zoologist yet he plays the guilt by association card on people infinitely more qualified than he. Not surprising since something like 60% of the IPCC sign-ons are from the biological sciences not climate or atmospheric scientists. (Most of the rest are "social" sciences, BTW)
People that study climate for a living overwhelmingly say this is a problem.
If I've got a large number of mechanics that say my car needs a new alternator, then I'd buy one. If I have a large number of surgeons that say I need surgery, then I would do it. That's not to say that you don't shop around, but at some point you make a rational decision based on evidence and testimony.
You're never going to have a climate model that is 100% accurate, but that goes for a model of pretty much anything. If you could measure every single variable empirically and produce absolute causal relationships, then why would you need a model?
If you live in a fault zone, a seismologist might tell you that your house stands a 1-in-50 chance of being destroyed by an earthquake in your lifetime (probably based on a model). And you decide whether to buy earthquake insurance. But, an overwhelming majority of climate scientists tell us that we are at an extemely high chance of some pretty bad consequences from climate effects induced by our actions, during our lifetime, and we do nothing. Actually, insurance firms are starting to take quick notice because they understand this principal.
