I believe in Global Warming (and other conversion stories)
Man-made global warming predicts the past with amazing accuracy. Its record at predicting the future is less impressive. Yesterday’s weather always seems to confirm global warming but it’s never predictive: when there’s a big hurricane, it was global warming charging up the weather, and the next year is likely to be worse. When the next year ends up with an extremely weak hurricane season, it’s global warming causing the ocean to calm down, and we’re going to have mild winters. When the next winter is extremely cold and snowy, it’s global warming again. When it’s warm it’s proof of global warming; when it’s dry it’s proof of global warming, when it’s wet it’s proof of global warming, and when it’s cold it’s either proof of global warming or weather isn’t climate.
In the last several years, we’ve seen that warm weather in Texas is the result of global warming; cold weather in England is the result of global warming; a powerful hurricane is the result of global warming, and a weak hurricane year is also the result of global warming.
It never seems to matter how the predictions come out, the result is always proof of man-made global warming.
One of the recent examples of that is a statistic about the number of record highs in the last several months. You can always search the statistics of the past for confirmation bias: there are millions of statistics, and you can throw out the ones that don’t help you. What matters is how well the theory you base on those statistics can make predictions. That’s what science is.
I saw those stats on Facebook, and commented that “the real test will be what predictions are made from this data.”
My Facebook friend’s response was not a scientific prediction made from a testable theory. It was an article titled A Message From a Republican Meteorologist on Climate Change. Paul Douglas’s article starts out like it’s addressing an AA meeting, and it talks completely about generalities, isolated statistics, and blanket predictions. It predicts everything so that it can never be wrong1, but predicts nothing measurable, so that it can never be disproved. It disparages proponents of applying science to the theory as enemies of the Truth.
I grew up Catholic, and I recognize Paul’s story: it’s a conversion story. Paul Douglas was driving out of Damascus, Minnesota and Mother Nature hit him on the head and said “be my steward”. This “Republican Meteorologist” didn’t look at the predictions of anthropogenic (human-caused) global warming as a theory, see that they predicted a mild winter in 2008/2009 and that the prediction held up. He couldn’t; it was the coldest in a decade. The next winter’s predictions were even further off the mark. He didn’t say that he looked at the predictions of increased hurricane activity in 2007 and that the prediction held up; 2007 was one of the mildest hurricane years in the past hundred years. He didn’t say that he looked up the predictions of snow loss in the Himalayas, or of any of the other disproven predictions of anthropogenic global warming.
If human-caused global warming were a scientific theory, the people who made those predictions would have moved on to something else; their theories were disproven.
The test for any scientific theory is, how can it be proven false? A theory that can’t be proven false no matter what happens is religion, not science. For example, these twelve months are not proof: they weren’t predicted. But suppose sometime in the next ten years there were 12 months with similarly-record-making lows. Would that be a disproof of global warming? What if temperatures had stagnated for the past ten years? Would that be a disproof?
Science needs theories that make predictions about both what happens when they’re right and how to falsify the theory if they’re wrong. Scientists do not try to prove their theories. They try to disprove them. A scientist with a theory will tell you how to disprove their theory. That is, they will either show that their theory makes a prediction which, if it doesn’t come true disproves their theory; or they will show that the theory predicts something not happening, and if that something happens it disproves their theory.
- What is the theory?
- How does it predict some future event happening or not happening?2
- How will that prediction be measured?
Then, and only then, do you get to “perform the experiment”. You don’t get to make predictions in hindsight; you don’t get to choose the measurements afterwards. Not if you want it to be science.
As John Tierney wrote on January 1, 2008:
But there’s bound to be some weird weather somewhere, and we will react like the sailors in the Book of Jonah. When a storm hit their ship, they didn’t ascribe it to a seasonal weather pattern. They quickly identified the cause (Jonah’s sinfulness) and agreed to an appropriate policy response (throw Jonah overboard).
You can always sift through statistics to find something out of the ordinary. Statistically speaking, there will always be something out of the ordinary: 50% of everything is above average. Parts of the United States are hot this summer; other parts were colder, but I wouldn’t be surprised if San Diego’s turns out to be colder than normal, too. We normally get at least a few hot days in July, and we haven’t yet. Now, there’s still time in August for hot days; if we do get hot days in August, I can expect that (a) there will be cold days in other parts of the world, and (b) those cold days will be ignored but our hot days will be proof of man-made global warming.
My Facebook friend wasn’t doing anything out of the ordinary proselytizing for global warming as if it were a religion rather than a science. Man-made global warming proponents tend to act more as a cult than as a religion, with instructions on how to talk with your relatives about the cause. It’s frustrating for those of us with a scientific background. Six years ago, a friend of mine was talking about how soon global warming was going to cause catastrophes. Within six years, the bay he lived one was going to be several feet higher; by 2016 it was going to be 12 feet higher. I have no idea where he heard that, but it doesn’t matter, because the failure of that prediction hasn’t changed his faith in global warming. He’s just turned to different prophets who are more careful to talk in terms of centuries rather than predictions that can be verified in a single lifetime.
Man-made global warming is an impressive theory; to become a science, its proponents need to start making measurable predictions that can prove their theory false. Instead, they hide their predictions and change their data. If man-made global warming were science, you wouldn’t see its practitioners seeing divergent temperatures between rural and urban measuring stations, and always adjusting upward to the higher temperature urban sites.
If man-made global warming were science, you wouldn’t see its practitioners predicting fifty million climate refugees by 2010 and then hiding the decline. Even natural evolution, where some things get bigger and some get smaller is proof of global warming: initially, global warming predicted smaller birds, but when birds started getting bigger, the researchers think that the trend is due to climate change.
The theory predicted one thing; they found the opposite. They decide that both results support their theory. That isn’t science. Science is making measurable predictions: predictions that specify both what will happen and how it will be measured.
Until global warming theory works in more than just hindsight, it’s not something we can spend trillions of dollars on, because there’s no way to plan for the future using a theory that can’t make predictions. If you think man-caused global warming is science, ask yourself “how can it be proven false?” When a religious leader predicts the end of the world on May 21, you know that when the end of the world fails to come, they’ll just re-predict the end of the world for October 21. Science doesn’t work that way. Science needs to be falsifiable, or it isn’t science.
And as Saul journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven: and he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?
And he said, Who art thou, Light? And the Light said, I am the Earth whom thou persecutest: do not thou be such a prick.
And he trembling and astonished said, Gaia, what wilt thou have me to do? And Gaia said unto him, Arise, and go into the Huffington Post, and it shall be told thee what thou must do.
And Saul arose from the earth; and when his eyes were opened, he saw no man: but they led him by the hand, and brought him into the Huffington Post.
And he was three days without sight, and neither did eat nor drink, nor browse the Web for Porn.
And there was a certain disciple at the Huffington Post, named Ullman; and to him called Gaia in a vision. And he said, Behold, I am here, Gaia.
And Gaia said unto him, Arise, and go into the street which is called the Internet, and inquire in the house of Ariana for one called Saul, the Republican: for, behold, he prayeth, and hath seen in a vision a man named Ullman coming in, and giving him a homeopathic remedy, that he might receive his sight.
Gaia said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Republicans, and conservatives, and the confused voters: for the voters are confused at the poor track record of our alarums.
And Ullman went his way, and entered into the Huffington Post; and diluting his medicine to make it powerful gave it to Saul to drink, and said, Brother Saul, the Light, even Gaia, that appeared unto thee in the way as thou camest, hath sent me, that thou mightest receive thy sight, and be filled with the Holy Green, and shall be diluted to the nth degree that thou mayst be most powerful.
And immediately there fell from his eyes as it had been scales: and he received sight forthwith, and arose, and was baptized in the name of global weirding, and went forth to make alarums in Gaia’s name.
- August 19, 2012: The 329th consecutive month of hot temperature adjustments
-
You can always sift through statistics to find something out of the ordinary.
This is especially true when you control the statistics. For example,
July was the fourth-warmest such month on record globally, and the 329th consecutive month with a global-average surface temperature above the 20th-century average, according to an analysis released Wednesday by the National Climatic Data Center (NCDC).
However,
Actually, 864th, but matching the numbers sounds better. It’s all a matter of what statistics you choose to look at. But, as I said in July, you don’t get to make predictions in hindsight; you don’t get to choose the measurements afterwards. The most important part of this chart isn’t that the numbers are being adjusted upward, it’s that they’re being adjusted differently every year.
At first it was global warming, but when the globe didn’t cooperate it became climate change. And when the theory still didn’t allow for predictions, it changed to global weirding. The word itself half-invokes the supernatural, and is specifically chosen to avoid a testable theory.
↑Or, how does it predict the outcome of some experiment? But while there are a few experiments, such as the CERN cloud experiment, for the most part we can’t do experiments on the weather, we can only make predictions.

So, yeah.
1. What is the theory? That human activity is causing the surface temperature of our planet to rise.
2. What does it predict? NOT THE WEATHER. Anyone on either side who uses single weather events or even seasons to prove or disprove global warming is trying to prove or disprove statistics with a single roll of a die.
It DOES predict long-term weather trends. It does not say that there will be no places with record cold temperatures, but it does say that there will be more record highs around the world than record lows. And that's been happening for a while now, and at least in the short term (with dicey statistical significance) seems to be accelerating.
3. How will that prediction be measured? Note that the study you cite about adjusting for thermometer siting also agrees that the temperature is rising. The dispute is over how much. Measurements will continue to get more accurate over time, and that's a good thing. If this downward revision turns out to be more accurate, that's good news for everyone.
As you point out, science should always be challenging itself, and while it's easy to find blowhards on both sides of the equation to chuck stones at, there are a lot of good scientists working to understand what's going on, and to diminish their work because some dimwit said there'd be catastrophe by 2012 is doing everyone a disservice.

The problem is that those dimwits predicting catastrophe and hiding their failed predictions are the scientists in the United Nations and other politically-funded research bodies, setting policy and funding other dimwits. The 50-million climate refugees by 2010, for example, came from the U.N. Environmental Program, and when their prediction failed completely the prediction was scrubbed; and then re-released a few months later with 2020 as the target date.
Can you be more specific about the prediction you mention? Provide a link that describes the mechanism which will cause the expected results, the prediction, and the pre-agreed measurement? (Too often, the measurements are chosen while they are being measured, to ensure that the prediction came true.)

Blowhard = policy maker has never been more apparent than in the "what to do about global warming" debate.
In my very very brief search (gotta go to work), I found this, but it isn't much use without references to the actual studies involved. Not really worth bothering with except as a reminder to me to do more digging later.

OK, I promised a reference, and here it is. I've been sitting on it for a long time because I didn't want to throw it out there without well-reasoned commentary. Alas, the following commentary will have to do.
Anyway, there are a lot of places that cite the same study. Here's one of the calmer ones:
Record High Temperatures Far Outpace Record Lows Across the US.
Some things worth noting that the article may not make clear:
1) That bar graph is not about absolute numbers, it's about the ratio. You might look at that graph and conclude that record highs are way up, but in fact they're not. Each bar is the same length.
2) Over time, you would expect fewer record highs and record lows. After ten years of collecting data, a new extreme temperature would be common. After a thousand years, a new extreme would be unusual. With a smaller number of extreme events, the ratio will skew faster.
3) This data is based on the same temperature stations we discussed above. Remember though, the dispute about those stations is not whether things are getting warmer, but how quickly they are getting warmer.
4) Back to the ratio business. Record highs have not increased that much, but record lows have dropped off significantly lately. Unfortunately, this is consistent with greenhouse warming, as less heat is radiating back out into space at night.
5) I found it painfully funny reading the comments to these articles, in which a handful of chicken littles took the data for the last two years, drew a logarithmic graph and concluded that the earth would be a million degrees next week. Not really contributing to rational debate there, fellas.
6) Not sure if it was this article of one of its sisters who carefully explained that the data did not come from the UN. That's how much credibility that august body retains on this issue.
But even taking all the above points into consideration, there's still the conclusion: things are getting warmer. Broad statistical averages that span decades (the time frame of climate) are swinging. The argument about whether it's the result of human activity or not is silly; either way we have to deal with it.

The predictions made by Meehl will require waiting until 2100 to do anything—that’s when we know if their models made an accurate prediction. And even, then, this is typical of the global warming science I’ve read elsewhere: besides putting the prediction so far into the future that it’s practically useless (I doubt that you posted that example because you want to wait until 2100 to start fixing the problem), but it already contains so many weasel words that they have already started making excuses if their prediction is wrong.
“This is our prediction based on our models. The actual results may be higher or they may be lower, and even our current model clearly doesn’t match the problem at hand.”
The argument about the cause of the issue is paramount: we are currently, especially in California, being asked to expend massive resources on fixing the problem. We are diverting our scientific resources away from identifying the problem and toward fixing a problem that’s barely more than a guess. If we end up fixing a cause that wasn’t the problem, what then?

Sorry for the slow response.
An important thing to remember when reading the above or any other article: It's not science unless the writers make an honest effort to enumerate the ways they could be wrong. It would be far more alarming if the article did not discuss sources of error.
Do not pay any attention to any so-called scientist who does not openly address sources of error, no matter how enticing their theories. This goes for nutritionists and boson-hunters, and everyone in-between.
Even in the part of the article you quote, the greatest source of uncertainty is future human behavior. That's encouraging, actually. And even here, even if you assume the greatest error margins, the conclusion is that the earth is not heating up as fast as people say, but it's still heating up.
My statement that the cause doesn't matter is simply wrong. The cause does matter. I feel dumb for not deleting it after I abandoned a tedious discussion of prevention vs. mitigation. Even the twenty seconds of review were not enough for me to realize that it was a silly thing to say.

Ah, and I have to say that the predictions most certainly do no "require" waiting until 2100 to do anything. By that logic we should not act on any prediction. "Forecast says rain tomorrow afternoon -- but we won't know until then, so let's plan out picnic anyway."
Obviously the difference is the confidence in the predictions, but we will be improving our confidence in climate predictions for decades to come. Skeptics play an invaluable role in this process, even if like Richard Muller they eventually say, "oh, I guess you guys were right all along. You're welcome."

I chose 2100 because it was the only verifiable prediction I could see in the article (assuming pre-determined measurement methods, which I’m giving them the benefit of the doubt as existing but being too boring to put in an article).
I’ve just re-read the article and it’s still the only verifiable prediction I can see. What in that article was your example of “if this does/does not happen, his theory is false”?
