The scientific method is the greatest invention of the modern age. For centuries, its practitioners have transformed civilization using rational systems revealed through careful observation. Theories which have succeeded not by virtue of their popularity but because they correctly predicted unknown phenomena are especially awe-inspiring. However, predictions without rational justification or those vague enough to be confirmed by any number of observations should not earn the same recognition. I’m a huge fan of Karl Popper regarding falsification, the idea that a scientific theory must predict some observable event which would prove it wrong (if the theory is wrong). This principle eliminates uncertainty regarding how specific a valid theory must be. Unfortunately, it has been ignored by some academics who claim to be scientists so that people won’t laugh at their ideas. You might have already guessed that today I’m targeting the low-hanging fruit of global warming alarmism. Prepare to be offended.
I won’t waste your attention picking apart the various temperature series, criticizing the IPCC models, or citing evidence of misconduct, not because those arguments have already been made by more qualified individuals, but because they shouldn’t even be necessary. Fundamental problems with any apocalyptic hypothesis make the whole enterprise seem ridiculous. This is what Popper says about scientific theory:
1) It is easy to obtain confirmations, or verifications, for nearly every theory – if we look for confirmations.
2) Confirmations should count only if they are the result of risky predictions; that is to say, if, unenlightened by the theory in question, we should have expected […] an event which would have refuted the theory.
3) Every “good” scientific theory is a prohibition: it forbids certain things to happen. The more a theory forbids, the better it is.
4) A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.
5) Every genuine test of a theory is an attempt to falsify it, or to refute it. Testability is falsifiability; but there are degrees of testability: some theories are more testable, more exposed to refutation, than others; they take, as it were, greater risks.
The scenarios published by climate modelers don’t qualify as scientific predictions because there is no way to falsify them – updated temperature measurements will inevitably correlate with some projections better than others. And fitting curves to historical data isn’t a valid method for predicting the future. Will the IPCC declare the CO2-H2O-feedback warming model invalid and disband if the trend in the last decade of HadCRUT3 data continues for another decade or two? How about if the Arctic ice cap survives the Summer of 2014? I’m supposed to trust these academics and politicians with billions of public dollars, before their vague predictions can be tested, because the global warming apocalypse they describe sounds more expensive? This riotous laughter isn’t meant to be insulting, we all say stupid things now and then.
Doesn’t the arrival of ScaryStorm Sandy confirm our worst environmental fears? Not if we’re still talking about Karl Popper’s science. Enlightened by the theory of Catastrophic Anthropogenic Global Warming, academics were reluctant to blame mankind for “exceptional events” only two months ago. They probably didn’t expect a hurricane to go sub-tropical and converge with a cold front as it hit New York Bight on the full moon at high tide less than six weeks later, because that kind of thing doesn’t happen very often. Informed news readers might have been expecting some coy suggestion that global warming “influences” weather systems in the rush to capitalize on this disaster. But in a caricature of sensationalism, Bloomberg splashes “IT’S GLOBAL WARMING, STUPID” across a bright orange magazine cover, and suddenly enormous storm surges threaten our infrastructure again while the seas are still rising slowly and inevitably, all because of those dirty fossil fuels.
I don’t mean to say that we should actually expect scientific integrity from a stockbrokers’ tabloid, but Mike Bloomberg has really sunk to a new low. He spoke at TechCrunch Disrupt a few years ago and seemed like an average business-friendly mayor, not a shameless propagandist. I guess the soda ban was a bad omen. It’s a bit discouraging to see another newspaper endorse the panic, but then the organizers of our climate crusade have been pushing their statist agenda on broadcasters for a long time.
On Sunday, the New York Times doubled down with this ridiculous melodramatic lament, written by one talented liberal artist. Where’s a prediction about the next exceptional event, folks? Is it going to be a tornado or earthquake, or does it matter? Are there actually any rules for preaching obnoxious hindsight to believers? Can anyone suggest an observation that would falsify the theory?
What will the temperature anomaly or the concentration of carbon dioxide measure in ten years? How about one solid date for the eradication of a low-lying coastal city? If you must predict the apocalypse, it is only somewhat scientific if you can rationally argue for a deadline. And the science is only settled when the world ends (or doesn’t end) on time.
Plus ça change, plus c’est la même chose. Happy 2012.
