One other interesting point to add to the list. If you look at plots of historic CO2 estimates derived from the Vostok ice core [1], you'll notice that we are presently at the very peak (in time) of a climate cycle that aligns almost perfectly with four other cycles from the last ≈400k years. Now two points here: 1. It is extremely unlikely that anthropogenic emissions would align so conveniently with the tip of a na…

There's also evidence that CO2 lags temperature increase historically, meaning CO2 was not the causative agent for temperature increase, rising CO2 might be an artifact of increase temperatures.

At that point you're questioning pretty basic physics. What part of the influence of CO2 concentration on the infrared transmittance of the atmosphere are you questioning [0]? Extraordinary claims require extraordinary evidence.

Oh, wow, okay. That changes the perspective quite a bit. Thanks!

There's a lot of issues with depending upon solely nuclear to solve these problems, but I'd like to see nuclear in the mix. Unlike the MIT model, components of electric generation are not simple linear systems that exhibit the superposition principle. Renewables need a whole lot of moderate-term storage and over-provisioning to get to where we want to be, and nuclear could help ease that by providing a source of depe…

It has a residence time in the atmosphere of 72 hours. Water vapor only works as a feedback. It isn't a prime mover of climate change.

The sun is the prime mover of climate change, literally everything else is feedback. If increased temperature creates increased water vapor, and increased water vapor causes increased solar radiation retention due to greenhouse effect (resulting in further temperature increases), that's a positive feedback cycle. Water vapor is undisputed as the the #1 greenhouse gas.

The sun has been ruled out already.

No, it has only warmed, otherwise we'd be in another ice age.

> The periodic variability in earth's orbit should have us cooling ever so slightly

That is only a single input. The other input is solar activity, which has increased. Also, if there is indeed a positive feedback loop, after the earth reaches X degrees, then water vapor will continue to increase the earth's temperature absent a reduction in solar input large enough to stop the loop.

> same warming as what brought us out of the ice age is false and has been known to be false for a long time

It's not known to be false, that's just nonsense.

Look how hot it used to be: (from [1])

Crocodiles above the Arctic Circle!

But keep telling me how CO2 is going to cause the planet to combust.

Case in point, I believe in climate change... that it's man-made (so to speak), that it results from higher than normal levels of carbon, that it will cause sea level rise, etc. But I disagree on some core orthodoxies. I think the root cause is deforestation / removal of carbon sinks, and a even lower-level root cause is simple human overpopulation.

The problem is that this is a tragedy of the commons situation. For every individual actor, taking action is detrimental because the cost is paid by the individual but the benefit is broadly distributed over all actors. Tragedy of the commons type situations can be overcome by some sort of binding legal framework. This is why no one is proposing for any single country to solve the problem alone, but rather to coordinate internationally.

As a side point, morally speaking western nations have a particular responsibility because they are the ones who caused most of the increase in CO2 levels since industrialization. True, China is the biggest emitter now, but that is a fairly recent development.

Theres no sources that support that, but ok.

Solar activity has been declining for 40 years exactly at the same time as the planet has been warming to record high temps. Solar has been ruled out not only through direct observation, but also through the nature of the warming. The lower levels of the atmosphere are warming fast while the upper reaches like the stratosphere are cooling. This is because the heat is being trapped at lower levels by the increasing greenhouse effect. Also night time temps are increasing faster than day time temps. Both of these are fingerprints of greenhouse warming and not solar.

These are too abstract for most humans. Someone needs to do a layer on top of this that instead has options like: - fake meat becomes widely adopted and we stop farming cattle - electric cars see 50% market share adoption Tangible things anyone can wrap their head around.

> - fake meat becomes widely adopted and we stop farming cattle

You can simulate that by tuning deflorestation to a minimum and methane to a lower value. Spoiler: it makes approximately no difference.

Yes it is. Milankovitch cycles are in cooling mode and they don't work at these speeds. Nobody besides internet crackpots are blaming milankovitch cycles.

Crocodiles above the Arctic Circle!

What was the co2 concentrations back then?

Nobodys saying the planet is going to combust, but thTs a nice strawman.

Some thoughts for your consideration, delivered with collaborative intent: > I have a bunch of coworkers that think scientists are making up this data and skewing results because their jobs depend on it and they want to continue to get funding.

Disclaimer: the style in which I write this reply is highly likely to be considered highly antagonistic, provocative, and non-constructive. Indeed, it may very well be this in many ways. But please consider the possibility that the actual underlying intent is other than what you might presume it to be...that there may be a method to my madness.

> I do not harbor this same suspicion, however, I'm determined to learn whatever is necessary to understand it.

Let's find out.

> Not because I can argue a point to completion for someone who doesn't share epistemological solidarity with me...

I doubt we differ much in actual epistemological beliefs, but rather my epistemological beliefs are much more pedantically stringent than yours, and that my stance on climate change is much less ~identity-related (for lack of a better term) than yours. But, I'm very pleased that you introduced epistemology into the discussion, as I believe it is one of the more important issues in play.

> ...but because it might allow me to aid in whatever needs posterity has in solving the problems we are creating today.

Here we are in strong agreement.

> https://www.coursera.org/learn/global-warming

Here is where our respective analyses of the problem diverge, although I didn't happen to touch too terribly strongly on this aspect of my beliefs in the comment to which you are replying, but I will do so now (and, see my other comments in this thread).

Essentially, my belief is that "the" problem of climate change is not one of science, but one of psychology. It seems to me that the manner in which the issue is being framed/discussed, is roughly:

1. figure out the "the science"

2. figure out the technical solutions

3. implementation

This seems generally logical/reasonable to me, and is typically an effective approach in the field of engineering - well, if you don't look too closely that is. I believe that 1 and 2 are complete (or more accurately, complete enough), and we should now as a society be moving on to step 3. But this is where the wheels are coming off the wagon, is it not?

Implementation, in the real world, has the following dependencies: [Public Consensus] --> [Politics] --> [Human Psychology] (note: I wrote this in a different order in a prior comment, but I think this order is more correct). Public Consensus is (largely) achieved via Politics, and Politics requires interacting with and persuading people - as they are, not as they "should" be (Human Psychology).

So let's look at some examples of human psychology in action....

> I feel as if you should do so as well, as it's the only way to understand the scientific position, if [all you are going to do otherwise] is [attack them with conspiracy theory]

> Further, you want to disabuse others of speculation, but [you haven't taken the work to do so yourself].

> Now, you could go ahead and do all the work above [for every scientific point of view that you want to challenge].

Here I will urge you to consider this in the most open-minded, least self-defensive manner possible. Please try to be acutely aware of System-1 vs System-2 thinking [0], and do your best to disable System-1. In order to assist you in that endeavor, I will openly admit that my line of reasoning has the appearance of arguing in bad faith, gas lighting, non-constructive pedantry, you name it. My behavior is clearly suspicious.

1. Remember this discussion is taking place within a context of epistemic humility (what we know is true, as opposed to what we "reasonably think" is true, but do not actually know for sure)

2. Note that I have added [brackets] to several phrases

So here is my challenge to you: re-read what I actually wrote, and answer the question:

From where did the ideas come from, that:

a) I am going to act in a particular manner

b) my beliefs (or, rhetorical techniques) are (or will be) based on conspiracy theories

c) I accuse others of speculation, but imply I am not doing the same

d) what I am doing is "challenging scientific points of view"

Is it possible that your mind has formed a highly detailed internal model of who I am and what I'm all about, based not entirely on factual observations, but rather based on subconscious heuristic judgements? I hope you can realize and acknowledge this, because it is the essence of my entire theory. And to assist you in this endeavor, I will explicitly note that this behavior isn't "stupid" or unusual - this behavior exists, and is so highly tuned that it takes place entirely without our conscious knowledge, because it evolved this way. It is an extremely useful capability of the human mind, but while it delivers tremendous advantages under most conditions, it also brings dangerous disadvantages in certain situations, such as when 100% pure, disciplined, rational thinking and analysis is required to solve a problem (say, analyzing and predicting human behavior with respect to a specific complicated situation).

So, it "shouldn't" be too hard to recognize that this is true in an individual scenario such as this conversation. But consider this: what if the entire public discussion on climate change is failing due to a mass manifestation of this well-known human behavior (combined with bad actors in politics and industry, general human stupidity, etc). What if this whole thing is little more than one big misunderstanding?

I think this is an extremely interesting and novel way of looking at this problem. The issue is, how might one get a feel for how true this is? I have a few ideas (but not being the sharpest knife in the drawer, I could use some help):

- observe the nature of discussions/arguments on climate change - We very much like to think we are discussing "pure facts" (after all, to our mind is appears in crystal clear resolution that this is what we're doing, doesn't it!), but is this really the case? For each statement in a discussion, does it have any epistemic flaws? (And, if you present these flaws to the author of the comment, observe the response - not only of the author, but also of moderators of the platform you are on!)

- how many of the "facts" we use aren't actually facts, but rather factoids (ie: "97% of scientists agree....")

- do humans sometimes literally say things that they don't literally actually believe (something you can determine by engaging in controlled, deep collaborative discussions)

- do humans sometimes behave in obviously illogical, counter-productive ways, "cutting off their nose to spite their face", "scorching the earth", voting "against their interests" (that one could actually go in the factoid category as well)

So what's the point of this long, schizophrenic rant? My point is, I think a perfectly plausible, evidence-based case can be made that what is primarily preventing us from moving forward on this problem is not a misunderstanding of the science (which there definitely is, on both sides), but a misunderstanding of the importance of human psychology. And, I will provocatively (but speculatively) assert that a recurring refusal to even acknowledge this as a valid possibility, is in fact evidence that supports the very theory. My suspicion on why this behavior exists, is that on ~identity-related issues, it is simply human nature to blame one's opponent while absolving oneself of all guilt [1].

I am worried that once again, my effort at articulating this theory will be completely not understood, or completely ignored (again, behavior that I would assert is suggestive of the very theory), as if my comment didn't even exist. But hey, as I provocatively challenged you at the very start when you claimed you were "determined to understand": "Let's find out.". So, let's, shall we?

Nonetheless, I personally believe that this is actually the problem, so I will continue to beat this dead horse in hopes that eventually someone will actually consider the idea. Under the circumstances, this seems like the right thing to do, although I highly doubt my approach is optimal.

This is great and all, but what can we do about the people that don't believe this data? That's where the real issue is.

I don't think climate change denialists are the target audience for this, though.

I think this chart is extremely useful as a way to show people which approaches are more effective at mitigating temperature increase. For example, in my experience in this types of discussions, some people like to claim that "population control" should be a top priority. However, this page shows that the effect of it would actually be rather small compared to other approaches like carbon pricing or reducing methane emissions.
