"is trust a big deal? And the answer is: we do not know" Trust is a very big deal. The biggest deal. As long as you are not a specialist on climate science yourself, all you can do is trust. That is true for all scientific endeavors. We pick people we trust and more or less believe in their stance on things.

> Trust is a very big deal. The biggest deal.

100% agree. And yet, observe the lack of concern in the "pro" camp (some of it on display here) where there is clear evidence for reasonable lack of trust.

I'm not asking that you adopt my beliefs, but if you stop and think about this discrete (lack of concern over at least partially justified distrust) point, does it not seem to be potentially a big deal as well (in that it might actually be driving human behavior)?

> As long as you are not a specialist on climate science yourself, all you can do is trust.

I disagree. Just two of many alternative actions:

- do your own research, to try to get a feel for how trustworthy the message is (for example, are there any clear mistruths being peddled)

- do not assume the message is necessarily correct, and repeat it as if it is absolute fact. History has taught us this lesson.

> We pick people we trust and more or less believe in their stance on things.

Some people do, others do not.

Considering a political consensus needs to be reached, it seems to me that it might be worthwhile expending some additional mental horsepower on the lower level details of why we seem to be incapable of achieving this, rather than just guessing at why people won't get on board. It's rather disappointing that this notion seems to be considered dumb in a normally rational community such as HN, and that it does seem to be considered dumb among the intelligent is to me an extremely interesting and counter-intuitive phenomenon in itself, that also may warrant some investigation.

Well if your gut says so then I'll tell the scientists they can throw away their ice cores, tree rings, sediment samples, fossilized coral and pollen, etc. You literally give zero reason for disbelief. It just sounds unknowable to you therefore it is.

Not JUST my gut, friend! There was "7 °C (13 °F) of warming in just a few years" during the Younger Dryas (around 12,900 to 11,700 years BP). That is in your 130k year range. https://en.m.wikipedia.org/wiki/Younger_Dryas If you've got tree rings from that time that say otherwise, then by all means share. I'll tell my scientists to standby and wait for your scientists' call.

About halfway through the warming at the end of the last ice age there was a return to cooling followed by a rebound to previous warming conditions. It was most pronounced in northwest Europe, Greenland, and northeast north America. That's where you see the rapid 7C warming. Other parts of the planet were doing the opposite in a see saw fashion. The younger dryas is visible in the global temperature record, but it isn't as pronounced as proxies in those local areas.

It looks like a small hiccup in the middle of the warming. After the warming at the end of the younger dryas the planet was basically at the temperatures it would be for the entire 10,000 year holocene period. Which we are now above.

> Surely there was one model that happened to come up with the right prediction What does that mean? This "model" is someone sitting down and, using what we know of physics, calculating how something will warm up when you add some extra energy (in this case, the earth). You surely don't think that physics works by people randomly guessing answers and then one of them "happened" to be correct? You don't, do you?!

> What does that mean? It means that if you are dealing with a complex multivariate system where the behavior of individual variables is not perfectly understood, let alone the behavior in an interactive system, and you are building multiple systems to model the environment and output a prediction between 1 and 10, undoubtedly some of the models will be correct (since you are predicting within such a small range), bu…

Even zero and one dimensional ultra simplified energy balance models come pretty close to approximating how much warming we've had based on the amount of co2 we've released.

Global average temperatures are governed simply by the need for incoming energy to be balanced by outgoing energy.

You're confusing the complexity of weather with the complexity of climate. A lot of the value of increasingly large scale, complex, supercomputer based climate models is the spacial resolution to be able to tell people of particular regions how their local climate might be affected. For instance a lot of work is going into understanding how the monsoon season will be affected.

This is the right question and there is an easy answer: If all climate models are wrong, it still makes sense to reduce emissions, waste, garbage, cruelty to animals etc. Worst case would be that we "wasted" money on stuff that makes no difference to the climate.

A bit off your conversation, wasted money means lives lost. A direct example is, building, vehicle, and work safety tends to increase as people are more able to afford the extra costs of safety features. Those things are both cheaper and less safe in poorer countries. Another example is the 2008 world food price crisis which killed people and is partly attributed to biofuel subsidies causing food crops to be replaced with biofuel crops. There are surely much bigger and more indirect causes of loss of life like reduced future technology due to reduced research and industry as people can't afford fancy ambitious stuff.

You cite a lot of uncertainty about Solar activity! Sure, you can use models to make predictions for a date in the future. Then, you wait to see if you reach that date and the predictions come true. Then you can make qualitative assertions about the accuracy of the model, its shortcomings, and whatnot. Do we have evidence of past climate models making accurate future predictions?

Surely we have historical data to validate models with?! I'm no expert, but this all sounds very plausible to me. Some parts are even basic physics, like reflection and black-body radiation, which I'm pretty sure we have nailed down exactly by now. Other parts are uncertain: simplifications of topology, chaotic processes, methane content of melting grounds, etc. The model allows to answer "what-if" questions, and the…

> does it sound so unbelievable that we have a model accurate enough to predict the rough effect of additional CO2 on global temperature?

Yes, it does sound unbelievable because CO2 is a tiny fraction of the atmosphere, and water vapor is approximately 2.5% of the atmosphere while also being the strong greenhouse gas.

It's a giant fraud used a political tool for the brainwashed masses.

a) Please forgive my annoying point-by-point communication style. My belief is that it adds clarity and precision, but I realize it's also annoying.

b) Everything I should should be read in the spirit of "in my opinion"...I see this as an exploratory conversation about unqualified armchair theories, not a statement of facts.

> I started responding to your GP comment, but I moved it here (and lightly edited/expanded it) to let you know that I see you

Sincere thanks.

> (though your pivot from "suspicion" and "bias" to "psychology" and "identity" makes me leery).

Suspicion, bias, identity, and a whole schwack of other things, all fall under the domain of psychology. But I don't ask that you accept anything I say at face value, I will address any questions you have, and consider all criticism.

> Without specific cited examples I'm not sure if you're talking primarily about

It's like 90% armchair psychology, based on non-acedemic education, and a fairly long period of close observation of human interactions. I claim no authority on the subject, I only ask that people think, and be honest (or at least try). That said, the possibility remains that I may not be entirely incorrect, even out of sheer chance.

> Our primary tool for communicating, human language, didn't develop to meet complex communication needs (be they scientific, technical, philosophical, etc). Some concepts are hard or impossible or tedious to communicate in language. Worse, these can get folded into nuanced domain-specific terminology or unstated shared context among practitioners.

Exactly. And this isn't news to anyone, but what I think might be somewhat of a novel/underinvestigated idea, is how these things manifest in day to day interactions, and in turn affect subsequent behavior, such as the influencing of peers, voting patterns, etc. Has there been any academic study into this? Should there be (are the stakes high enough that out of the box thinking might be warranted, or are staus quo ideas getting the job done to an acceptable degree)?

> I won't impute, but if you see this in climate science and not everywhere--do investigate why.

It appears on any culture war topic, which is why culture war topics are often banned from being discussed in multiple communities. But again, what I find interesting, is the unwillingness for people to discuss the specifics of why they are banned.

> Not that I would know where the Overton window is, here--but I get the impression from how you frame this that you think you are further outside of it than I think you are.

This is an ever-present risk, and it's undoubtedly a motivating factor in my choice of when to wade into discussions, but I think(!) I've managed to become fairly disciplined in actually discussing things in an honest, mostly emotionally detached manner.

My framing of it is certainly not a comprehensive overview of the subject, and I have tried to go to great lengths to acknowledge that. My intent is to not discredit or derail the climate change initiative, but rather to introduce the idea, for consideration, that perhaps our perceptions of the nature of "resistance" or "disagreement" may not be accurate, and in turn our solutions/response to that may be suboptimal. Maybe I've done a less than perfect job of communicating this idea, but I see little evidence that others are making any effort to understand. Rather, it seems that my lack of complete agreement is immediately considered to be disagreement, and therefore dealt with accordingly. Any pushback seems to invoke an authoritarian, tribal response.

> I wonder if you're seeing (something like?) Dunning-Kruger here--many (but not all) of the people left arguing on the internet about facts and gigatons and global cooling and ivory tower conspiracies may just be identifying at each other.

Of course. But again, this isn't so much what I am pointing out, which is the amazingly widespread inability and unwillingness among intelligent people to step out of this mode of thinking, or acknowledge clear signs of it.

> In any case, I'm unsure what practical application this realization has (beyond the obvious--lobbing fact-grenades into the other trench doesn't accomplish much). Do you see applicable lessons, here?

At this point, I think there is some potential value in investigating how true some of these theories are. Is the fact that climate change is (has become) a culture war topic interfering with people's ability to discuss or think clearly about the matter, or does group identity trump everything (System-1 overpowers System-2, ~without exception, even among the intelligent). I believe some clear patterns can be observed. If so, what to do with this knowledge?

> One lesson can be that the message should come from someone with a lot of identity overlap.

Yes indeed! If the requirement is mass persuasion (and it very much is), and the topic is identity-related (causing the human brain to malfunction, resorting to tribal, System-1 thinking), then adopting an approach where the message is delivered via influential figures in various sub-communities seems like a very logical approach.

Which raises the question: do we see any of this happening?

> I think it's useful, but it takes a while to scale well (for example, you need people willing to risk ostracism and exclusion from groups that are core parts of their identity; people most knowledgable about the science don't have a lot of identity overlap).

Agreed. Assuming this theory is sound, scaling is a big problem. Perhaps some people who are smarter than me in the HN community have some related expertise in the field, or just some good old-fashioned smart ideas to consider. But how one might persuade them to think about the problem from this perspective seems like a difficult nut to crack. I will continue doing my best (as you can see I am not deterred by ostracism and exclusion, and @dang seems content to let me go about my business), but if you have any good ideas, I'd love to hear them.

Even if we could get everyone's sentiments pointed in the right direction, there are a lot of other seemingly unrelated issues that may need to be taken into consideration, but if a higher frame of enlightenment (willingness to cooperate, MAYBE) could be established, perhaps we could fix several problems at once. Dare to dream, eh?

> Katharine Hayhoe is a decent case study, here. She stays busy, but I don't have a good sense of how readily she can move the needle with skeptics. Either way, her identity doesn't seem to defuse the regular conspiratorial comments on posts/videos about her.

To me, sending a climate scientist to deal with skeptics is like bringing a knife to a gun fight, or trying to put out a grease fire with a bucket of water. You need a lunatic to deal with lunatics, because you need to understand how they think. Authorities and rationalists have high-resolution perceptions of how deniers and conspiracy theorists think, but they are only perceptions, almost completely manufactured by their minds. No wonder no one can make any progress with them.

> I find the discussion of memes in The Selfish Gene useful here. It's worth a read if you haven't. Considering the "fitness" of individual memes, fellow travellers, and memeplexes as a whole (i.e., their virality, whether they fit in well with or oppose other common memes, how resistant they are to displacement, etc.) is a good place to start with evaluating how climate change denial slots into people's broader belief systems.

150% agree, the propagation of "knowledge" via memes is fundamental to this problem, but it is key to realize that it is not only "deniers" who are thinking in memes (as opposed to reasoned logic) - this is how everyone is thinking, if to varying degrees. This is well known in the fields of psychology and neuroscience, and few here would dispute it within a thread on that specific topic. But try raising the notion in an unrelated topic, particularly a culture war topic, and watch people's logic exit the room instantaneously (yourself being an obvious exception).

Many thanks for the conversation, any criticism of anything I've said is appreciated.

There is research that found the massive local population extinction after America conquest was linked to the planet cooling in that period, so I'm quite sure reducing human population either literally (by limiting growth) or virtually (by reducing consumerism/consumption, which is the key for limiting pollution) or both! will help a lot https://www.bbc.co.uk/news/science-environment-47063973

Genociding multiple continents isn't exactly a model I want to follow. "Population control" will continue to be Nazi-speak as long as it applies primarily to post-colonial countries, which while having high birth rates, also contributed minimally to CO2 emissions.

birth-control should be globally enforced nowadays (don't know how, but it just must be since the vast majority of people have an environmental footprint way too big), as the state of environmental problems is serious. Along with other levers to ease this climate crisis

I'd like to draw your attention to something. Notice how you've dropped a key idea that @adventskalender pointed out: "And once people see one of your arguments is shoddy, why should they give your other arguments the benefit of the doubt?"

I think this type of behavior is interesting, common, and potentially consequential.

> 1) This statement is fundamentally irrelevant to the (scientific) discussion, because it does not contain a scientific argument.

And yet, it is commonly repeated on a regular basis in the "scientific" discussion, despite not being technically true.

> It could be 0%, it could be a 100%, that wouldn't change the validity of any of the scientific arguments presented.

It changes the rhetorical/persuasive value of it though.

Perception of truth is.

> the point that a consensus broadly exists in climate science is correct

Then say that, rather then falsely report the statistically tortured "97%".

I see only more rhetorical support for the number, not mathematical support. Not that it matters really, just sayin'.

> But your point is also wrong: I am not a climate scientist, and the whole discussion can be followed with a bit of high school physics, chemistry and biology, plus Wikipedia to fill in the gaps. Your next point shows that you were unwilling to put in that effort, but it isn't actually that hard ...

It may not be hard to "follow it", but what does that expression mean, and what does it not mean. I'm fairly certain it doesn't mean understood at a level sufficient to form epistemically sound conclusions. Again, high marks for persuasiveness, but I don't find this line of reasoning convincing. But that's me.

To be clear: I say this not in dispute of the actual science of climate change, the axe I am grinding is related to the nature of the conversation around it. I am hoping some people might become more willing to consider the possible detrimental consequences of the way this topic is discussed.

Pointing out that 95% (or more) climate scientists say that climate change is happening is not appeal to authority, but appeal to expertise. The former is a logical fallacy. The latter is not.

If the statistic was actually true it would.
