Never mistake consensus for truth
Fake news: the math behind the "97%"

There is probably no better explanation of why this stat was cooked up than the op-ed by Lawrence Solomon in the Financial Post of Jan 3, 2011.

In other words, those in charge of the IPCC who would like to claim the authors of their report ran into a snag - the scientists who contributed data to this thought in some cases the conclusions were nuts. How then to portray confidence in the IPCC results?

Enter Maggie Kendall Zimmerman, writing her masters thesis in 2008 and her advisor, associate professor Peter Doran. Sadly what their report showed that of all the scientists polled, 75 out of 77 people getting climate grants think warming is man made and a problem. You can't even show all people getting climate grants believe the AGW hypothesis. And 99.9% reject it.

Maggie and her thesis advisor decided on online poll of scientists but the they started out ignoring any scientists unlikely to yield the "proper conclusion". Anybody having anything to do with space was ruled out and never mind this means all the climate researchers at NASA and CERN who have hard evidence the sun has more to do with warming than anything else.

Of these remaining scientists only about 30% bothered to answer the throwaway questions posed in a tiny online email survey - many scientists apparently reported it seemed trite and ignored it. These are the questions:

1 When compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant? 2 Do you think human activity is a significant contributing factor in changing mean global temperatures?

Only 90% answered the first question in the affirmative.

Only 82% answered the second question in the affirmative and that's with only 90% of the respondents (recall the other 10% presumably know it was warmer than now in: 1936, 1300 and 0AD) So roughly one in five people did not support the idea warming actually existed at all. Not entirely unreasonable when you realize the summer of 1936 was hotter then any summer since and it was evern more hotter in 1300 and even hotter yet in 0BCE.

82% doesn't sound that airtight so they excluded people that hadn't published a climate paper in a year. This took the number of respondents down from 3000 to 300 but the confidence percentage was still not newsworthy.

So, next round of cuts: limit responses to those who self identify as "climate scientists". Quoting the thesis itself:

The moral of the story is if you can't show consensus then cherry pick and by this method they were able to identify 75 people in the whole world who believed warming is man made and disastrous.

The thesis is availeble here: http://probeinternational.org/library/wp-content/uploads/2010/12/012009_Doran_final1.pdf

It's a two page quickie, the first page has the 97% explanation.

Statistics can be useful when the questions asked are intelligent, the sample size large and random. This is a clear case of cherry picking to zero on on the desired answer. So, 97% (of 77 people on climate grants) think AGW is real and harmful.

99.97% of the rest of scientists (~10K) don't agree.

The latter is actually more meaningful than the former.

Cook et. al. (2013) have a more accurate breakdown of her "work":

...and trash it more formal sense and in greater depth; the statistical methods in Doran are now taught in university statistics classes at, at least my Alma Mater as how not to use statistics.

So in conclusion when you assert "97% of the worlds scientists support the AGW hpothesis" you're really saying "75 people out of over 10,000 agree" and you might as well say "99% of all scientists think AGW is batshit insane".

But what you're really saying is:

1) That is, the logical fallacy of the argument from ignorance.
2) That is, the logical fallacy of proof by authority.

In essense when somebody says "97%" they're admitting they know noting of climate and nothing of the mathematics the field of climate science is based on. Recall the warming hypotheis was from a model and the measure of a good model is how well it tracks reality. It neevr has of ocurse, the models blew up years ago and it's not warmer each year than the previous year like the models predicted, not have the ice caps or snow packs on mountains metled. In fact you will not be able to find a single prediction made by climate alarmists that ever came true.

Not a single one, ever.

Even if the statistic were true, so what? It's still the fallacy of the argument from ignorance and argument from authority. This is not a replacement for truth, it's an opinion. To restate in more compare terms: never confuse consensus for truth

This not evidence that would hold up in court. The only reason it holds up in the court of public mind is nobody bothered to check what the number meant. Percent? Percent of WHAT?

Not much it turns out. Note also this quote from Legates Et Al (2013)

  • "Students must understand not just what is known and why it is known to be true but also what remains unknown and where the limitations on scientific understanding lie. Fact recitation coupled with demonizing any position or person who disagrees with a singularly-derived conclusion has no place in education."

  • "We have nothing to learn from savages"

    In 1535 Jacques Cartier sailed from France to Canada and accidentally got stuck over the winter by mistake, they'd planned to return to France before the snow flew. They began getting sick from scurvy. Near death, Cartier sought help from the natives who gave them bark tea from the "tree of life" (Arbor vitae) and they got better and returned to France the following spring they told of their miraculous recovery unprecedented in sailing thus far and were told flat out: "We have nothing to learn from savages".

    Citrus as a cure for scurvy was discovered by the British Navy shortly after. Good ideas travel fast.

    In 1931 Pauling wrote his paper on the chemical bond and the fields of biochemistry, quantum chemistry and molecular biology wre founded. Observing Klenners clinical tiral tht cured 60 out of 60 poliopatients with intravensous asocic acid, he was then vilified by the vaccine industry.

    99% of scientists knew a bacteria didn't cause ulcers. It does.

    Scientist proves H. pylori caused ulcers by drinking it.

    There were all sorts of theories on why stomach ulcers happen. On scientists having trouble getting people to listen when he had hard evidence a bacteria was the sole cause. So he drank some, on camera, got an ulcer than cured it. That's how ulcers work he asserted.

    97 (or better) percent of doctors were sure it was not a simple and eaisly cured bacterium. The problem with that thinking is the fallacy of the argument from ignorance: if you don't know what causes it you don't know what doesn't either. "Don't know" means "you don't know".


    95% of scientists agreed the continents did not move.

    100% of geologists were sure continents did not ever move.

    "97%+ of geologists agreed the continents were stable. It was Settled Science. Hundreds of research papers supported it. Overwhelming consensus. And wrong. And, oddly (not really, if you think about it a moment), it was not a geologist but a meteorologist, Alfred Wegener, who ultimately showed all the mutually agreeing geologists they had it all wrong; the continents move." - Dr. Michael K. Oliver


    100% of scientists thought Komodo Dragons were not venomous.

    It was long-believed that the mishmash of deadly bacteria was a weapon that the world's largest lizard used while stalking its prey. People used to think that a Komodo dragon would use its razor-sharp teeth to bite whatever it wanted to eat and then follow its victim until eventually a bacterial infection slowed the animal enough so the dragon could enjoy its meal. But around 2008 or '09, Scientists embarrassingly discovered large venom glands in the lower jaw of Komodo dragons. (Venom, obviously, can't be cured with antibiotics, since it's not a bacterium.)" - Underdone Comics.


    Now ask yourself why you think warming is true.

    We hear about "climate denier" a lot.

    1) Science advanced from skepticism. Either a flaw is found or the hypothesis is made stronger.

    2) To use rhetoric instead of truth in an argument it means there wa no truth. It's always easier to explain why rather to to point out why you think the other guy is wrong.

    I Don't need to say "he's a liar who can't add" if somebody asserts 2+2=7. I'd just say 2+4=4. Mmmkay?

    3) Now, where is this proof carbon dioxide causes an increased yearly average temperature? Is "yearly average temperature" a meaningful idea and number?

    Do you now the answers to these questions?

    Why do we see more articles on climate than pollution when pollution kills millions a year while climate change - which was all based on some models that y 2012 had failed - has never killed anyone? Plus, also falsified by the end result of the ozone hole thing. Seen that?

    Are yu aware this is a partisan political issue and not a scientific one? This all comes from the Clinton Foundation which recycles pollut dollars into fake climate news and memes.
