What Do Scientists Think About Global Warming?

In my previous post, I mocked the common tactic of listing as many scientists as one can find opposing a scientific consensus. They do it frequently for scientists who disbelieve in man-made global warming, but also for creationism and other subjects.

Here's a list of 2,648 people whose "doubts about AIDS are publicly known," for example. It includes scientists, doctors, nutritionists, lawyers, pharmacists, engineers, and for some reason a large number of mathematicians and physicists.

By contrast, the Republicans in the Senate only came up with 650 scientists who don't believe in man-made global warming. (Here is the document (.pdf) linked to in a comment on my previous post by Ezzie with the claim that "science disagrees.")

As I pointed out in my last post, listing the number of scientists who hold position A tells us nothing useful without also listing the number of scientists who hold position not-A. (It would of course disprove the argument that NO scientists believe in A, but nobody actually makes that claim. It's a straw man argument.)

So, because I'd like to know what's likely true rather than propagandize for a point, I thought I'd look into just how many scientists really don't believe in man-made global warming as compared to the number that do.

Examining the Scientific Consensus on Climate Change (.pdf) is the most recent answer to that question that I could find. (I found it in the very well-sourced wikipedia article Scientific opinion on climate change.) Published just last month in Eos, Transactions, American Geophysical Union, a publication of the American Geophysical Union, the paper details the results of a poll of 10,257 Earth scientists (with 3,146 respondants.)

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?

The answers:
Results show that overall, 90% of participants answered “risen” to question 1 and 82% answered yes to question 2. In general, as the level of active research and specialization in climate science increases, so does agreement with the two primary questions (Figure 1). In our survey, the most specialized and knowledgeable respondents (with regard to climate change) are those who listed climate science as their area of expertise and who also have published more than 50% of their recent peer-reviewed papers on the subject of climate change (79 individuals in total). Of these specialists, 96.2% (76 of 79) answered “risen” to question 1 and 97.4% (75 of 77) answered yes to question 2.

They then compare these numbers to the beliefs of the general public.



Okay. So the public is divided, but the 82% of scientists and 97.4% of scientists specializing in the subject come out on the same side. Yes, it's a web survey, and yes, "is a significant contributing factor" is probably too vague. But all of the other surveys (there are several more referred to on that wikipedia page, for example) come to similar numbers.

Here's just one more:
In 2007, Harris Interactive surveyed 489 randomly selected members of either the American Meteorological Society or the American Geophysical Union for the Statistical Assessment Service (STATS) at George Mason University. The survey found 97% agreed that global temperatures have increased during the past 100 years; 84% say they personally believe human-induced warming is occurring, and 74% agree that “currently available scientific evidence” substantiates its occurrence. Only 5% believe that that human activity does not contribute to greenhouse warming; the rest are unsure; and 84% believe global climate change poses a moderate to very great danger.[75][76]

I think it's safe to say the large majority of scientists believe in man-made global warming. Could they be wrong? Of course, anything's possible. But what could be the basis for assuming that they are wrong, let alone the extreme confidence with which many on the right make that claim? I submit it's pure wishful thinking combined with a reflexive rejection of anything the "other side" believes. Al Gore devotes his post-VP life to "spreading the gospel," ergo the gospel must be false. And did you hear about his mansion?

These scientists are aware of Martian warming, and of sunspot activity, and of all the thousand other little straws the deniers have grasped at. They are professionals in the field, and they've heard it all. But they still believe. To assume that you, a layperson, can better interpret the evidence than the majority of scientists is pure hubris. This isn't the kind of thing where everybody's opinion is equally valid. It's the kind of thing where some people are experts and most others are just talking out of their asses.

Presumably none of you deny the HIV-AIDS link, and even most of my religious readers have accepted that evolution is true, so why cling to this position? What good reason do you have? How can you be so sure?

And please, please stop with the "X number of scientists believe this!" garbage.

Atheist 13

I've been tagged by that other Jewish atheist, The Atheist Jew, with a meme of ten questions:

Q1. How would you define “atheism”?

There are at least two kinds of atheists: Those who do not believe in God and those who believe God does not exist. I'm among the latter.

Q2. Was your upbringing religious? If so, what tradition?

I grew up in a relatively left-wing Modern Orthodox tradition.

Q3. How would you describe “Intelligent Design”, using only one word?

Desperation.

Q4. What scientific endeavour really excites you?

Neuroscience. Also, genetics, nanotech, robotics, and AI.

Q5. If you could change one thing about the “atheist community”, what would it be and why?

I'd like to see it become less a community of the bitter and wounded and more a community of those who share a common philosophical stance.

Q6. If your child came up to you and said “I’m joining the clergy”, what would be your first response?

It depends on the kind of clergy. Humanistic Chaplain/Rabbi? "Wow, that's great!" Orthodox Rabbi or Catholic Priest? "Maybe we should have a little talk..." Ultimately, it's their life.

Q7. What’s your favorite theistic argument, and how do you usually refute it?

Without God, I can't see how we have free will. It appears that we have free will, therefore God must exist. Curiously, nobody seems to make this argument except me, on Opposite Day.

My refutation is that we actually don't have free will. This has disturbing implications, which I have not yet come to terms with.

Q8. What’s your most “controversial” (as far as general attitudes amongst other atheists goes) viewpoint?

I don't think there is a "general attitude among other atheists." Among atheists are secular humanists, libertarians, Randian libertarians, doves, and hawks. Perhaps I have more respect for some religious people than many atheists do.

My psychologist is an Episcopal priest, for example.

Q9. Of the “Four Horsemen” (Dawkins, Dennett, Hitchens and Harris) who is your favourite, and why?

Dawkins, by far. Even though he sometimes goes too far as activists tend to do, his book The Blind Watchmaker blew my mind. To be fair, I haven't read much of the others. Hitchens, though, strikes me as a pompous blowhard.

Q10. If you could convince just one theistic person to abandon their beliefs, who would it be?

Great question. Let me think as I type:

Osama bin Laden? Nah, I don't think that would much matter at this point.

Rav Aharon Lichtenstein? Too selfish. While I would love to see a prominent Modern Orthodox rabbi publicly admit there is no God, it just wouldn't matter that much in the grand scheme of things.

Ultimately, I'd like to convince that kid or young adult who thinks they're a bad person because of their sexual orientation or sex life or curiosity about the outside world or lack of religious fervor.

Now name three other atheist blogs that you’d like to see take up the Atheist Thirteen gauntlet:

XGH, although he's only admitted to being an agnostic, Abandoning Eden, and Lubab No More.

Atheist Attrition Rate

In response to my post about Orthodox attrition, Orthoprax asked about atheist attrition.



The answer, at least as far as the GSS goes, is that 51.3% of people who had no religion ("none") at 16 still had none when they took the survey. This number appears to be lower than the major religions' retention rate but higher than Orthodox Judaism's at 27.3%.

An Inside View of Scientology

An interesting slashdot comment from an ex-Scientologist on what he calls their "reality tunnel."

Orthodox Jews might find that some parts of his story hit a little close to home:
Anyone who attacks the church is either a suppressive person (2.5% of the population who are evil - think Hitler), PTS due to a connection to an SP (Potential Trouble Source - 20% of the population), or has committed various other overts and withholds (ie sins and secrets) and it trying to justify their own actions by making the Scientology seem less (because if you admitted to yourself that Scientology was the "one and only solution" then your otherwise small crime would have to weigh fairly heavily on your conscience).


It is also taught that if someone encounters the OT3 materials before being ready for them, then as part of the psychological conditioning to create "prison-planet" earth, the person may get sick and die and this is the reason it is considered "confidential" and heavily protected, and only available to members of the church past a certain level.
(Zohar, anyone?)

This "truth" or "reality tunnel" is slowly conditioned into you until you internalise it. There is a huge taboo against reading or discussing anything potentially negative or "entheta" against Scientology or the church, often the taboo will extend down to the point that you feel it is wrong to "think" about potentially negative things regarding Scientology. To do so would potentially detract from Scientology and is thus a mortal sin against humanity, or you might wind up making yourself sick. I know this, because I was brought up within the church, and through the process of leaving the church and the Scientology "reality tunnel", it took me around two years to fully confront this internal taboo to the point I could openly think and speak on the subject.


Well back to the original question of do David Miscavage, Tom Cruise and the others running the Church, truly believe in what they say? My guess is that they do, they are so fully immersed in the Scientology reality tunnel, that they cannot actually see outside of it. Once you start questioning it, the contradictions become obvious and starts to crumble fairly quickly (it can be scary if you have nothing to replace with), so instead it is accepted 100% as a matter of faith to the point that they have dedicated the whole of their lives to this mission of "clearing" the planet, and "handling" anyone who gets in their way. There is too much at stake (the whole future of mankind) to even consider the possibility that they might be wrong or deviating from their course.

What Do Orthodox Jews Really Believe III, and Why Don't They Speak Up?

(Previously: one, two.)

XGH, DovBear, and Ezzie all link approvingly to this answer from James Kugel about what the implications are to Orthodox Judaism if the Torah is not divine. The comments at XGH's are well worth reading, as well.

The question is in response to Kugel's recent book How to Read the Bible: A Guide to Scripture, Then and Now. Kugel is a Biblical Scholar and a professor at Harvard, who believes in the Documentary Hypothesis but nevertheless considers himself an Orthodox Jew.

Anyway, here's the gist of the question:
I suppose I am writing to you to get your thoughts on how a religious person can maintain his/her faith and fealty in and to a rabbinic system that is so directly based on the belief of a Divine text and the “Four Assumptions”? I fully realize that I am asking this question to a Bible professor who happens to be observant rather than to a Rabbi - I am more interested in the former's response than the latter's.

And the answer in full:
Before getting to the specifics of your e-mail, I should say something exculpatory (I hope) about this book in general. It really is not addressed specifically to Orthodox Jews, or even to Jews as a whole. I think there’s been some confusion about this. I’m a Bible professor, and the purpose of this book is to teach something about the nature of modern biblical scholarship – something that the general public, and even quite a few modern scholars themselves, are largely unaware of (i.e., the great gap separating ancient and modern scholarship, and the crucial role of ancient interpreters in shaping the Bible’s message). It’s true that, in the last chapter, I also tried to offer some thoughts about how different groups, including what I called "traditional Judaism," might try to reckon with the insights of modern scholars, but if that were all I was out to do, the book could have been considerably shorter.

A second point is also worth mentioning – and this is a bit closer to the subject of your e-mail. Orthodox Jews (myself included) are, by definition, people who like to be told what to do. We accept eagerly the whole “prepared table” of Judaism – not just the idea of avodat H’, but all the detailed plan that goes with it. In fact, the general idea alone would not get us very far (this was the oft-repeated theme of my book “On Being a Jew”). And so, it is part of the whole posture of seeking to do God’s bidding that we absorb ourselves in the details of the traditional way of life, "davening three times a day" as you say, and kashrut and learning and Shabbat. We don’t take easily to going beyond this, looking up from those daily tasks to contemplate our Employer, that is to say, to think about the really basic issues of theology. In fact, to talk about such things even seems to us un-Jewish; it is neither a necessary nor a particularly comfortable activity for someone who has undertaken to live as an Orthodox Jew. If it ever does come to such basic questions, I think our preferred path is, as in the details of halakhah, to look to our classic texts to tell us what to think. I’m sure I’m not telling you anything you don’t already know.

The problem posed by modern biblical scholarship is that it calls into question some of the most basic teachings of Judaism, and, since it really is modern, its specific arguments are not addressed by our classical sources. So what should a Jew think about modern scholarship? As I said, I wrote this book for a broad audience from different religions, but as far as Jews are concerned, my purpose was certainly not to get them to incorporate into Judaism modern scholarship’s version of what the Torah is or where it came from. In fact, I think I recommended pretty clearly at the beginning of the book that people of traditional beliefs think twice about reading it, and at the end I said outright that modern biblical scholarship is altogether incompatible with traditional Jewish belief and
practice. In other words, I think that if you want to be an Orthodox Jew, the Documentary Hypothesis and the other insights of modern scholars can have no place in the way you study Torah. (This, by the way, puts me at odds not only with the stance of Conservative Judaism, but also with a fair number of biblical scholars who describe themselves as Orthodox.) I really don’t even buy the idea that you can go halfway down the modern path, adopting the linguistic or philological insights of modern scholars but not the rest. Ultimately, all roads lead to Wellhausen.

But the question I tried to address in that last chapter was: bedi’avad, what is someone who has heard or learned something of modern scholarship (and this includes an increasingly large number of Orthodox Jews) to think?

I know that the answer of some people, perhaps a great many people, is what your e-mail calls “burying their heads in the sand,” though perhaps we should rather call it: “trying to stick with Judaism’s traditional teachings by ignoring or dismissing what modern scholars say.” I really have nothing to say against such a stance. I know perfectly well how much is at stake for most people in adopting any other position. For the same reason, I feel pretty sure that most Orthodox Jews will continue to declare modern scholarship off-limits.

But I also know that this is not an adequate response for some people – not for you, according to your e-mail, and truthfully, not for me either. It just feels wrong to say about anything that really matters to you, “Well, I know that scholars have turned up a lot of disturbing facts, but I don’t want to know about them.” My impulse, anyway, is to face the truth as best it can be known and then try to make sense of what it is telling us.

In your e-mail you say that if modern scholars have proved that the Torah is not a "divine document," then our whole system of halakhah collapses. I don't think I'd ever accept that premise in the first place: modern scholars may have proven a lot of things, but I don't think they've ever tried to determine what is or is not divinely inspired, simply because there is no litmus test by which you can decide such a thing. Words are words, whether written by prophets or interpolators or editors, whether written in this particular set of circumstances or another; the words never carry little flags identifying some of them as divinely inspired and others and ordinarily human.

I believe what I just said is absolutely true, but I wouldn't want to use it as a cop-out to avoid addressing what seems to me to be the real issue. Modern scholars have said a lot of things that are indeed upsetting to traditional belief: they've cast doubt on the Torah's reliability as a historical account of things that actually happened, they've highlighted contradictions within the text, and so on and so forth. Doesn't this indeed undercut the Torah's standing as the basis of our whole way of life?

Forgive me if I restate some of the overall argument I made at the end of the book. (I know you didn't find it particularly convincing the first time around, but I'm hoping this time I may say it better.)

When you actually consider Judaism as it is, the role of the Torah in it is really not what you say it is. Ultimately, Jews are not Torah-fundamentalists. On the contrary, our whole tradition is based on adding liberally to what the Torah says (despite Deut. 4:2), sometimes reading its words in a way out of keeping with their apparent meaning, and sometimes even distorting or disregarding its words entirely. (My book “The Bible As It Was” contains seven hundred pages of examples of how this all began.) What’s more, as everyone knows, much of what makes up the daily fabric of Jewish life has only a tenuous connection, or no connection at all, with what is actually written in the Torah. I mentioned such things as saying the Amidah three times a day, the berakhot that we recite before eating and on other occasions, netilat yadayim, many aspects of kashrut [e.g. basar vehalav], many of the particulars in the way we keep Shabbat and holidays, studying the Babylonian Talmud, and so on and so forth. Isn’t this an awful lot of what it means to lead a halakhic life? On the other hand, one might also mention such practices as mekhirat hametz, which on the face of it seem in fact to contradict what is written in the Torah, in this case, the prohibitions of bal yera’eh ubal yimmatze. And all these are really only the tip of the iceberg; you yourself could go into much greater detail on this theme.

So someone looking at this situation from afar would probably be reluctant to accept your assertion that the whole system of halakhah depends on the words of the Torah and their divine inspiration. (Of course I am aware that our Rabbis sought to find within the Torah itself the source of their own authority to add to or depart from the Torah’s own words, but I think our outside observer would rightly point out a certain circularity here: It is only the rabbis’ own, authoritative interpretation of a certain verse in the Torah that grants them the right of authoritative interpretation. In any case, this is a formalist argument, one that doesn't really speak to the larger issue.)

No, this observer would say, it is simply not true that the whole system of halakhah depends on the words of the Torah. Those words were the starting-point, but what has truly proven determinative in them (indeed, what was recognized as such from the start) was the general direction that those words point in and embody, and whose trajectory was then carried forward through the Mishnah and Gemara and all later writings. That "general direction" is the basic idea that Israel's connection to God is to be articulated through avodat H'. This is the whole substance of the Sinai revelation, and whether it took place at Sinai or somewhere else, biblical scholarship itself has highlighted the utter disconnectedness of this idea from all that preceded it. Before that moment, there was (for centuries) the God of Old, who appeared and disappeared; and there was the offering of sacrifices in the temple. Then, suddenly, the phrase la'avod 'et H' acquired a new meaning: it meant doing all these mitzvot. That changed forever the whole character of divine-human interaction, and it's that change that all later Judaism embodies.

As I said before, Jews generally don't like to think about such things, and talking about a "general direction" or overall character of the Sinai revelation is particularly disturbing for people who are otherwise so devoted to studying specific words and actual texts. But I think if you want to be absolutely accurate, you have to admit that, time and again, it's not a matter of the specific words, at least not if you try to see the big picture. What really underlies everything -- and what was the ongoing substance of the Sinai revelation -- was the revelation of a new way of being connected to God.

In the light of all this, I hinted at the very end of the book at what is called in German a “thought experiment.” What would happen if someone could demonstrate definitively that God had truly given only one commandment to Moshe at Mount Sinai, the one in Deuteronomy that says: “You shall serve the Lord your God with your whole heart and soul.” Then He said to Moshe: “Okay, you and the zeqenim and their later successors can work out the details.” Well, this is a somewhat jarring question, but please go along with it for a minute. In the end, I do not believe that this would, or could, invalidate our system of halakhah. Of course I do believe in nevu’ah, in divine revelation, and I don’t think that Israel got only that one commandment from God. Theoretically, however, I think it would be enough if that were all, since that would provide the firm basis for everything that followed -- Moshe's, or Rabbi Akiva's, elaboration of how this primal divine commandment is to be carried out. Because ultimately, any Jew must admit that at some point the divinely-given text leads to the human interpreter and the poseq, indeed, to this specific taqqanah and that specific gezerah shavah. And frankly, we don't really seem to all that aware of, or even care much about, where the dividing-line falls. This is our “prepared table,” the work of many hands. If someone wants a different table, let him go ahead – but this is the Jewish table, the way Jews serve God.

As one of our sages said: to what may the matter be compared? To a man who wished to see the King. So he went to the royal palace and stood outside and waited for the King to appear. After some hours, the King did come outside, and the man was thrilled. But soon the King went back inside the palace. The man returned the next day, and the next, and sometimes he did catch a glimpse of the King, but always only for a few seconds, and then his view would be blocked by someone, or the King would step behind a pillar or get into his carriage and ride off. What had at first been thrilling now became only frustrating.

Eventually, the king’s close advisor became aware of the presence of the man standing day after day outside the palace, and he approached him and said: “I know what you want, but you are going about it the wrong way. Go up to the palace door and ask to work inside – it doesn’t matter what: janitor, guard, woodcutter or water-drawer! Then you will enter the palace by right and see the King as a matter of course; indeed, He will recognize you and perhaps even call you by name.” And so the man did, and it was just as the King’s advisor had said: he saw the King up close every day, and the King called to him by name.

This is the whole idea of Judaism. If you want to come close to God, the only way is to become His employee. Understanding that avodat H' is the true foundation of our halakhah may not de-fang modern biblical scholarship; a lot of what it says will always be disturbing to Jews. But I think that modern scholarship does not, because it cannot, undermine the essence of Judaism or what Jews actually do in their lives; it cannot, as you suggest, cause the system to collapse.

That was not my whole purpose in writing this book, but it was one thing I wished to say, because I thought it might be of help to people like yourself. Of course I knew – I knew this even before I began writing – that some people would be upset by the book, and I knew that their natural reaction would be to attack me. I must tell you I really don’t mind. I know that for such people, even contemplating modern scholarship is off limits for an Orthodox Jew, so anyone who does so must be condemned. But after all is said and done and Kugel is long gone, the problems raised for Orthodox Jews by modern biblical scholarship will remain. My hope is that the response I’ve outlined here, which is really what I said in somewhat different terms in my book, will also be around for a while, and that it may help people like yourself to look squarely at those problems and at what seems to me to be their only truthful resolution.


In other words, it doesn't matter if the Torah came directly from God as told to Moses at Sinai, because the Torah itself isn't that central to Orthodox Judaism!

Now I agree with him that Orthodox halakha (law) is so far removed from the words of the Torah that the Torah itself is almost irrelevant. E.g., the Torah says not to cook a calf in its mother's milk and today's Orthodox Jews wait 1-6 hours after eating meat to eat milk, have separate dishes and silverware for milk and meat, and even sometimes separate dishwashers and ovens. The Torah says "an eye for an eye" and the Rabbis made it "compensation for an eye." The Torah says to bring sacrifices and the Rabbis turned it into saying prayers.

But as Kugel admits, "modern biblical scholarship is altogether incompatible with traditional Jewish belief and practice," so it strikes me as a strange leap to go from, "Oh, we've built so much on top of the Torah that it doesn't even matter if it turns out not to be from Sinai," as if the Torah were just a mold for the halakha that could be discarded once the halakha itself was built.

But yet he persists as an Orthodox Jew.

Many other Orthodox Jews no doubt would take issue with his self-identification with them, but I wonder how many others secretly agree, or have similar thought processes.

So far, we've seen in this What Do Orthodox Jews Really Believe series, that Jews who call themselves Orthodox might believe that the world is billions of years old, that Adam and Eve were mythological, that the Flood was either mythological or greatly exaggerated, that the Exodus was either mythological or greatly exaggerated, and now that the Torah itself very well might have been written by several different people and wasn't given at Sinai at all.

This doesn't give us any indication of how many Orthodox Jews believe these things, but it does give us an idea of the range of beliefs one can hold while still considering himself or herself Orthodox. There are X number of Orthodox Jews who believe that the earth is less than 6,000 years old and that Bilaam really had a talking donkey and then there are Y number of Orthodox Jews who believe that the Torah was written by men, albeit divinely inspired, and contains mythology, historical errors, and presumably other non-divine things, like maybe the whole idea about gay sex being an abomination. And, of course, there are Z number of Orthodox Jews who believe some combination of the above beliefs or any number of other ones and, perhaps the largest group of all, W number of people who are either incurious and simply take everything for granted or specifically avoid thinking about certain topics and dismiss out of hand any contrary arguments.

If Y is a large number, though, I think what we have is an enormous sham. Kugel is open about his beliefs, and so is XGH, at least pseudonymously, but I have to guess that they are just the tip of the iceberg. There are tens of thousands of modern, intelligent, educated, and curious Orthodox Jews in America who must be asking themselves these questions and arriving at some pretty similar answers. Kugel put it perfectly: once you start asking, "all roads lead to Wellhausen."

Is there a vast well of Orthodox Jews who believe these things in private but are afraid to speak up?

Do they have a responsibility to speak up?

A whole generation of intelligent, curious teenagers are feeling ashamed and scared for having doubts and questions about Orthodoxy's legitimacy. A whole generation of adults is stressing out every day about following to the letter an increasingly stringent and incomprehensible set of laws. Families are divided when some of us go "off the derech" or, God-forbid, marry a non-Jew. A generation of Chareidi (ultra-Orthodox) youth, especially the girls, are being shortchanged in their secular educations and career prospects. A whole generation of Orthodox gay children are being raised with the belief that God considers gay sex an abomination and worthy of death, even if we no longer execute people for it.

How many Orthodox people lied to me, overtly or by omission, when I was a teenager wondering how people could really believe this stuff? How many betrayed the gay kids I went to school with by keeping silent when they were taught at every turn that their desires and feelings were wrong? Why are the fundamentalists the only ones talking honestly about their beliefs?

I think the other denominations of Judaism have a lot to do with people's reticence to speak up. If the modern Orthodox suddenly started talking openly about these beliefs, they would instantly create a new denomination, de facto if not de jure. They don't like what they see in Conservative, in Reform, in Reconstructionist, or in Humanistic. They desperately want the ultra-Orthodox to consider them Orthodox. They want to maintain Orthodoxy's retention rates. They want to keep Orthodoxy's strong communities. They think that they'll lose what they love about Orthodoxy if they admit what they really believe, and they're probably right.

These are just my guesses. I have no way of knowing how many people believe these things, because people aren't talking. Maybe the blogs will change all that. Maybe if people have a safe avenue to explore forbidden thoughts, something new and better will come out of it. Or maybe it will just be the end of Modern Orthodoxy. Or maybe nothing will change, because that's just how the world works.
