Climate nonsense

I’ll get this out of the way first – I’m a skeptic whenever the people predicting/promoting something depend on the thing they predicted/promoted continuing so they can get another taxpayer funded grant so they can continue to predict/promote the subject.  Thus I am skeptical of man-made global warming.

Note that I am not denying climate change – the climate has changed MANY times in the past, and the earth has been both much hotter and much cooler than the current climate.  Man wasn’t even around during most of the previous changes – our recorded history only goes back about 6000 years, and the oldest agricultural based civilization discovered so far is about 12000 years old.  It’s interesting that that corresponds to the beginning of the current interglacial period….

Who caused the previous climate changes?  Isn’t it even a possibility that the small changes in climate we’ve measured over the past 100 years are entirely natural?  Where is the evidence that is man CAUSING climate change?  (Again, I’m not denying that climate change may be happening – I simply do not think it’s been proven that man is the cause of any climate change which may be happening.)

With that out of the way, I ran across this web site while reading through a small wind newsgroup email tonight.  In his email, the author dismisses a study contradicting his view by saying “Both articles referenced in this thread are deceptive attempts to create sensationalism where there is none. In both cases a single new observation has changed the results of climate predictions by a tiny amount. The magnitude of the changes are carefully not mentioned because they are trivial.

I find that statement from him strange because on his website he talks about chaos theory and how it’s misunderstood.  On his website (linked above) he states “That is why we have the butterfly effect. Quite literally, the flapping of a butterfly’s wings in South America could cause a storm in Europe a few years later.”

To which I say bullshit.  That’s the same as saying when I cough or fart, I could cause the moon to wobble on it’s axis or purple aliens to emerge on Mars.  There is ZERO basis for such a ridiculous claim, and the burden of proof is on the person making the outlandish claim.   It’s also interesting that Lorenz first used the term when quoting a meteorologist who was making fun of Lorenz’s own faulty weather modeling scenario.

Anyway, he can’t have it both ways.  He cannot (logically anyway) claim that “the flapping of a butterfly’s wings in South America could cause a storm in Europe” yet dismiss a factual  observation as “trivial”.

Note: Entering incorrect data – even a small error – into a calculation is not the same as a seagull flapping it’s wings.  Or me farting.  Just because a computer model exaggerates the error does not mean it actually happens in the real world.  For an ancient example of how something may be valid in math, yet be totally wrong in practice, you can read about Achilles and the Tortoise.

There’s so much more here, but I’m not going to get into a point by point rebuttal of it tonight.  But I do want to quote one more section.  Towards the bottom, he states: A big shake-up is required. In 2008 we received a warning shake in the form of the credit crunch. (Excuse me, but WTF does he think the unsustainable debt loads of companies and individuals has to do with global warming?  The answer is in his next few sentences…

Instead of governments spending incredible sums of money supporting the very organisations that caused the problem they should be injecting the funds into helping the victims of the deceipt [sic] and into reviving the economy by funding clean renewable energy. Until this happens I am reliant on this website to raise the cash I need to take real practical steps toward delivering clean energy solutions.

As he clearly states – he’s in this to raise cash.  And until the government (you and me via taxes) gives him the money he wants, he’s trying to scare people into giving him cash.  As “proof” of the dire nature of his predictions, he says “It could well get out of control to the extent where we would not be able to stop it at any price! As the planet gets hotter the methane would be released even faster until it could kill all life on earth! If you do not believe me read my essay about SETI.

Ok, I “do not believe him” so let’s see WTF his essay on SETI has to do with global warming…..

Hmmm…. The only unbreakable laws we know of are the laws of nature. I propose that there is such a law and that it is called “Free Will”. Until enough of us ask for contact from friendly aliens they will stay strictly outside the realm of our senses.”

This sounds suspiciously like churches asking people to pray for rain, or world peace, or a sick friend…. If you’d truly believe in it, it would happen.  Even if there’s absolutely zero evidence for it.

He sort of sounded believable when sticking to basics about global warming, but saying that we can’t contact the “friendly aliens” because not enough of us are asking for contact is strictly wacko stuff.  No science, no theory, this isn’t even a fucking hypothesis!  It’s a mad man’s delusion….

Sorry, he has some webpages with assertions.  And he’s hoping his assertions will convince people to give him money – until he can get your money from the government without having to ask you for it directly.

Enough of this.  I’m not wasting anymore time on him.  The earth has gotten warmer since the 1980’s, and we don’t know why.  There are many theories, but I haven’t seen a single one of them that also explains why the earth got so hot from the 1920’s through the 1940’s.  A valid theory must take into account all known data – no exceptions.  When even one bit of reality contradicts it, it’s no longer a theory – it’s back to being a hypothesis.

Why is Darwin still controversial?

I’m just sitting here, minding my own business, peacefully surfing through the local news tonight, when I see this story in the Knoxville News Sentinel.  It’s titled “Knox schools say they don’t teach human evolution, but how the process relates to all life”.

The story starts out with this:

“We have the purpose of preventing bigots and ignoramuses from controlling the education of the United States.”

- Clarence Darrow, defense attorney during the Scopes trial in Dayton, Tenn., 1925

About 84 years ago, Tennessee was thrust into the international spotlight when biology teacher John Scopes went to trial in Rhea County and was found guilty of violating a state law that banned the teaching of human evolution in public schools.

While the state law was finally repealed in 1968, the teaching of evolution based on the theories of Charles Darwin is still a contentious subject.

Why is this “still a contentious subject” in Tennessee?  Why haven’t people in Tennessee learned from the debacle of the Scopes trial over 80 years ago?  Has anyone – anyone at all – produced a better explanation to explain how we developed?  Not that I’ve seen.  Note:  “God did it” isn’t an explanation anymore than “because I said so” explains something to a child.

“The fact that this debate continues is a sign that we missed our target to educate people about the scientific process,” said Becky Ashe, science supervisor for Knox County Schools.

“Scientific process” is simply another way to say “scientific theory”, but Ms Ashe wants to avoid that word because it’ll offend someone.  Since most of what I write offends someone, I don’t have that restriction.  Check out the definition of “scientific method” on webster.com and you’ll see this: principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses.

Scientists would have abandoned evolution long ago if it didn’t meet the above requirements – especially regarding the “formulation and testing of hypotheses.”  That’s the true test of any theory – does it correctly predict what will happen in a given set of circumstances.  Just like the theory of relativity, which predicted the atomic bomb, the bending of light by gravity, and the relative slowdown in time experienced at high speeds.  All of which have been tested and confirmed by numerous experiments.  If you need evidence, simply look at Hiroshima and Nagasaki.

Darwin’s theory of evolution is in the same class as Einstein’s theory of relativity.  It’s been confirmed by numerous experiments and observations.  There’s not a single bit of evidence that contradicts it.  But yet it’s still controversial in Tennessee – and Kansas, and wherever else ignorant people congregate in sufficient numbers.

The KnoxNews.com story I referenced in the first sentence of this posts also contains this paragraph: “A theory, to a scientist, is not just a guess. A theory is an overarching, unifying concept that is supported by, and explains, relationships between many different types of data and observations from different fields of inquiry. Thus, the theory of gravity explains why an apple falls from a tree, why the earth circles the sun, and why we don’t all go flying off the earth as it spins. So yes, we should teach the theory of gravity, atomic theory, cell theory, the theory of relativity and the theory of evolution by natural selection. … I know of no scientific alternatives to this theory. I am aware of a number of mythologies that address the creation of Earth and mankind, but they are not science and should not be taught in science classes,” Wellman said.”

Read that last line again – “I am aware of a number of mythologies that address the creation of Earth and mankind, but they are not science and should not be taught in science classes.Amen to that!

Biblical creation myths fall into the same class as Hindu creation myths.  And African tribal creation myths.  And Japanese Shinto creation myths.  None of them have A SINGLE SHRED OF EVIDENCE to back up their claims.  Yet they all claim to be the whole truth, nothing but the truth, so help me god.  And they want it taught in public schools.  And they wonder why they’re thought of as backwards hicks.

This is coming from a guy who grew up in a town of less than 100 in rural Missouri – I know all about hicks – I are one.  :-)   But that doesn’t mean I can’t learn and grow out of it.  Eventually.

And yet Tennessee allows ignorant parents to opt out of having evolution taught to their kids if they sign a waiver – which produces yet another generation of people ignorant of science.  Future scientists would do well to avoid this state if they’d like to learn anything that would actually help them learn to be scientists.

Hmmm….  This turned into a rant.  Oh well, deal with it.

Darwin’s 200th birthday is coming up on Feb 12th.  Read all about him here.  You can read his book “On the Origin of Species” online (or download it) in PDF format here.  Project Gutenberg has a plain text version available here.  Enjoy!
