<p>Oh, sorry Catahoula, I didn’t realize you were riding the denier’s hobby-horse du jour. A non-falsifiable theory is something along the lines of: “Because God wanted that to happen.” You can’t disprove that theory because God, as a Supreme Being, can make anything happen - no rules apply. But global warming theory is science - it’s just complicated science. You could disprove many of the parts of the theory, and by doing so, require that the theory be abandoned or revised to address the new proof. </p>
<ol>
<li><p>You could disprove the part about the Earth actually getting warmer - that was the first stop on the denier’s agenda, until it got kind of obvious that, well, it was happening. So that didn’t pan out.</p></li>
<li><p>You could prove that CO2 doesn’t absorb and emit infrared radiation in the way the theory posits, but according to what I read, that’s seems to be true, too. </p></li>
<li><p>You could disprove the part about the stratosphere and above actually cooling as the surface gets warmer due to the greenhouse effect, like on Venus. But I hear that that’s happening too. Etc. </p></li>
</ol>
<p>But I don’t claim to be able to verify all the scientific details myself. I really have to take the word of the people who do, that they actually check that stuff, and actually analyze the data to see if it really matches up. Unlike you, I don’t presume that virtually every climate scientist in the world is simply ignoring data which actually conflicts with the theory - you know, so they can stay on that big fat “gravy train” you go on about. (I’m picturing a bunch of nerds in lab coats, spooning up caviar and slurping champagne, laughing all the way to the bank as they scheme about how to keep those five figures salaries rolling in after a mere 10 years in college - and, need I add, how to rub out anybody who squeals.

<p>In other words, global warming theory is just like every other scientific theory that deals with lots of variables - like evolution or relativity. You can never affirmatively prove that it’s true. All you can do is confirm that the different assumptions upon which it is based seem to reliably repeat themselves - apples keep falling down instead of up, etc. And you look for evidence which is irreconcilable with the predictions of the theory - I know the deniers keep on after that, but they don’t seem to be convincing many people who carefully review their claims.</p>
<p>Speaking of apples and gravity - Newton’s theory of gravity is now considered to have been disproved. It’s close enough for everyday purposes, but not exactly right. It’s still pretty handy. I’d ignore it at your peril if you’re doing anything involving ladders or rooftops. Because even though it’s been falsified as an absolute truth, it’s predictive qualities are pretty darned good. We may similarly find that some parts of global warming theory are a little off the mark as well. That’s science. But in making decisions about how to address the predictions of climate change science, I’m inclined to follow the ladder-Newton precedent, no matter how inconvenient it might be.</p>
