RCP 4.5 is really bad as well. In our last project it was kind of the worst case scenario we considered. It means that rich countries will have problems adapting to the changing environment. The changes will happen so fast (20 Years), no new infrastructure can be built to prevent natural disasters (for example dam's). Poor countries have even less possibilities to adapt. For example countries like Kazachstan completely rely for it's water resources in summer on glaciers. In Switzerland we already know that all glaciers will disappear or melt by 80% to 90% in all likely scenarios.

What can an individual do to not suffer?
Invest in oxygen masks and a mountain cabin?
You should be asking what an individual can do to not starve to death or die of over heating.
Most answers are: move to a rich, powerful country not in the danger zone
There might not be any. Migration pressure from uninhabitable areas will keep mounting, and some of the countries in the "danger zone" have nukes.
With global changes this big, we can't expect the usual MAD Mexican Standoff a couple big powers to keep everyone safe. It may be that all nuclear powers (or all that remained after a brief nuclear war) will decide together to politely ask NZ to open up or else.
I say the people threatening with nukes here would turn to more subtle methods of invasion, that's their objectives. They won't destroy it because they can't have it. That'd be a waste of nukes.
Now is there someone threatening another country with nukes at the moment but not using them because he knows that'd be useless anyway and would it prove my point ?
Then I recommend you spend more time around people. Grown men have been convicted of throwing acid in an ex-girlfriend's face because "if I can't have you, no-one can."
> Now is there someone threatening another country with nukes at the moment but not using them because he knows that'd be useless anyway and would it prove my point ?
It doesn't prove your point because no country today is facing imminent extinction. Rationality changes when desperation comes into play.
> Then I recommend you spend more time around people. Grown men have been convicted of throwing acid in an ex-girlfriend's face because "if I can't have you, no-one can."
You come up with a stupid analogy based on children behavior and now you invoke people throwing acid ?
This is nickelodeon level debate here.
> It doesn't prove your point because no country today is facing imminent extinction. Rationality changes when desperation comes into play.
You are making the extraordinary (and quite childish considering you started with an analogy based on children behavior) claim that a country would nuke another one to go and settle there, it's up to you to prove it. So far, in the real world, no one has used nukes like that.
I'd follow the argument but if a guy would throw acid and was in position to throw a nuke over a country they were denied access to it's most likely plausible they have the means and resources to get into this country in a more discrete and safe way (safe as in: he's in a country that wasn't nuked).
It’s called an analogy. Given we’re talking about nuclear war, it’s not an insane analogy.
> claim that a country would nuke another one to go and settle there, it's up to you to prove it.
I never said they’d try to settle the wasteland. I think you’re struggling to understand the analogy.
> It’s called an analogy. Given we’re talking about nuclear war, it’s not an insane analogy.
It looks more like a slippery slope bias to me. You can "prove" any dangers with that analogy but it's running against what history and reality have shown us so far.
> > claim that a country would nuke another one to go and settle there, it's up to you to prove it.
> I never said they’d try to settle the wasteland. I think you’re struggling to understand the analogy.
True, true, somehow the "threaten to" stayed in the keyboard. I still stand by the fact that this analogy doesn't scale to the real world.
I have no idea what you’re talking about.
I’m simply making a point that humans don’t always behave reasonably in a way that would achieve their stated goals. I tried to use an analogy to make this easier but you seem confused. I could have replaced “acid” with “murder.” Would that have helped?
> I have no idea what you’re talking about.
Sorry, I reread the definition from the bias list and it's not the good one. Read the whole line, it's too small an illustration to fit a bigger picture:
> It looks more like a slippery slope bias to me. You can "prove" any dangers with that analogy but it's running against what history and reality have shown us so far.
> I’m simply making a point that humans don’t always behave reasonably in a way that would achieve their stated goals.
This, I agree with. But:
> I tried to use an analogy to make this easier but you seem confused. I could have replaced “acid” with “murder.” Would that have helped?
No. I understand your analogy but it happens that I disagree with how it is an argument in favor of your opinion (which I also disagree with but that's for another paragraph).
If anything, I think it undermines your position because it reduces the many more complex steps leading to nuking another country to a petty and cruel behavior from one individual. The analogy doesn't explain the reality behind a potential revengeful nuclear strike (geopolitical moves leading to that decision, climate disasters, consequences stemming from the reaction of other nations, etc.). All it is saying is "there are humans who would do crazy things so it follows that we are always at risks from one human doing the most crazy thing like nuking another country" but nuking another country, for the sake of the argument, requires more than one human (no matter how petty he is) and so far it hasn't been done yet (unlike people throwing acid at exes, which breaks the analogy). This is skewing proportions ("this analogy doesn't scale").
I'd rather we discuss the likelihood of such an event happening based on real world data and information, not using illustrations.
To follow on the analogy: unlike the guy with the acid bottle, the guy with the nuke has certainly the means to hop on a plane and buy his way into NZ rather than nuking it.
Of course we can always make the argument "but what if someone crazy comes and do the crazy thing" but how likely is it ? Adding "but what if he's under a lot of pressure ?!", that's still a what if scenario that would be better validated through real world examples/data than an analogy boiling down to "there are crazy people" or the single argument "people don't always act rationally so anything is possible. Well, duh.
On analogies, I like this blog post: http://itdept4life.blogspot.com/2012/04/why-analogies-suck.h...
That assumes money matters any more. It’s not unreasonable that we go past that point, leading to the irrational scenarios.
It’s hard to apply regular probabilities to this, since we’re discussing a situation where the best option for all humans is to get to New Zealand! We have no frame of reference for this scenario.
You have misunderstood the entire argument. Perhaps instead of calling other people stupid you should review your own reading comprehension.
If your civilization is on the verge of extinction then you are not concerned about wasting nukes. You are way overestimating human rationality under extreme pressure.
> You are way overestimating human rationality under extreme pressure.
Ironically, pretty sure the people with the power to launch nukes won't feel the same pressure as people suffering from climate change consequences. So.. keep the restless and angry gods content and they won't wage war and spread destruction.
A hypothetical country threatening NZ with nukes in this example would be presenting an argument: either let us in, or else we will nuke you - in hopes that NZ prefers being overcrowded but surviving, over being glassed. NZ will not take the deal - at first. The other country can insist more and more, until the situation is so tense that any random event could trigger launching the missiles.
And then, if NZ acquiesces and lets people from one country evacuate to their land, another nuclear country would ask for the same deal. Or they may even point half the nukes at the first country early on, to make sure that either they get the deal or no one else.
Thing with brinkmanship is that at no point anyone wants to actually use the nukes - but at every point it's locally optimal to up the threat, and there is no obvious stopping condition until someone trips over a cable, hits a launch console, and the nukes starts flying.
Before nuclear war, lots of constructive things like geoengineering could happen.
Do you think if e.g. India or Pakistan start experiencing lethal wet-bulb temperatures and people there decide to mass-migrate to survivable lands, only to be stopped at the border and denied entry, will those people and these countries just throw their hands up in the air, seeing there's nothing they could do, and accept imminent death? Or maybe they'll try to threaten or force to be let in, using any means available, up to and including nuclear weapons?
(This applies to all nuclear-armed countries - I mentioned these two, because AFAIK they'll be the first nuclear powers likely to experience lethal wet-bulb temperatures - but that's not the only way climate change could make a country mass-evacuate, and such other factors could hit other nuclear powers first.)
Nuking your desired safe haven is obviously a stupid idea. But threatening them with nukes so they accept you in, that's a reasonable negotiation tactic when you're otherwise up against the wall. If they refuse, making a stronger threat is an obvious next move. There is, however, no obvious stopping point before tensions are so strong that a small mistake - or someone at high enough level getting irrational - will cause the nukes to be launched.
All cooperative moves are much better than extended suicide - for both sides.
It's effective, because the other side is forced to bet their own lives on you eventually accepting defeat and agreeing to die, so that they may live. It's not an easy bet to make and stick to.
All cooperative moves are indeed better than suicide, but when we're at the point everyone wants to get to NZ, we're way past the time of cooperative solutions.
Also, assuming that there are only zero or negative sum moves left is a really big assumption.
If there was a viable geoengineering technology available, we'd be using it right now. Assuming that something will pop up is wishful thinking.
China? Norway? UAE? I feel like they will all fare very differently
Incapable not, but unwilling most certainly - just look at the state of politics across all Western countries and that doesn't even include China and India who're hell-bent on growth.
> What can an individual do to not suffer?
Move to somewhere high up north, these places are going to be those where climate change will at least not cause them to get uninhabitable.
Unwilling and incapable are sort of two sides of the same coin. Our political and economical systems are set up as a greedy (in the CS sense) optimization process.
This makes solving long term global scale problems all but impossible in any case that would entail any sort of short-term inconvenience, and anyone seeking to solve such problems by such means are (by definition) politically and economically irrelevant.
I think in general there's a somewhat unfounded notion that someone is actually in control that's getting harder to defend in the light of what's been several decades of fairly public failures to address obvious problems in society. You to look very hard to find examples of public policy successfully addressing any sort of problem, and even in that case it's questionable whether the problem was actually solved or whether it's just a case of regression to the mean.
I think it's obvious by now when all that began: with the collapse of the USSR and Yugoslavia in the early 90s. With the corrective against capitalism lost, everything defaulted to greed in the following decades.
Before that, humanity showed many times over that it could cooperate on critical crises and to ban dangerous stuff: sulphur in fuel was banned after "acid rain", lead and asbestos were banned, CFCs were banned after the ozone hole, nuclear weapon tests were all but abolished, biological and chemical weapon developments as well. Even the right to wage wars of aggression was under pretty solid control.
Does "suffer" take into account "transitive suffering" from children? (from future generations, our offspring)
i.e. if I'm physically fine but my child is suffering, I suffer too.
Now, for what one can do, there are always two ways: one is, as suggested, to find a better spot for oneself and let the others go to hell for all I care. But what about the children?
other is to become millitant, and force action. Worse outcome for oneself, but potentially a better outcome for the children.
Let's say we reduce that 2.43 ppm increment to 1 ppm at some point. Or even to 2.41 ppm. Does that mean we failed? In a way, yes. But was the effort meaningless? No, the 1.43 ppm we didn't put out in the atmosphere really had an impact, and in a similar way, the 0.02 ppm we reduced also had a real impact on actual people. Both would translate to less sealevel rise, less floods, droughts, storms, heatwaves, biodiversity loss, etc. Which means a reduction of death, migration, hunger, suffering, extinction, chaos, economic loss, etc.
I know your question is about adaptation and not mitigation, but we need to get out of the either/or mindset. Every single action we take to reduce our emissions matters. I mean that in a very matter of fact way, not as a call to action. It is just technically incorrect to think it does not matter (though by no means I am implying you specifically think so).
Be independent in all your supplies as much as possible (food, water, basic necessities). Cyclical gardens, Biosphere-2 like systems, etc. Then scale up and do the same with a small community. The bigger the community, more chances to repel an attack of cannibals.
There’s nothing you can do strictly by yourself in my estimation that will help over the long term.
The only way out is through as a team
Why? 1+1=2 2+2=4 3+3=6 And 0.5+0.25=0.75
When two people don't give it 100% you can't get the results you are looking for. Just ask anyone who has been divorced...
I watched a documentary about bread bakers in Afghanistan and there was a whole ecosystem of wheat growers, millers and bakers who were all centered around a river and had been doing the same work for many generations. They are screwed.
Beyond that you are supposing based upon bad data and conjecture which results in a scenario where worry will kill you.
But let's say the worst happens and you can't live in a city anymore. Can you grow your own food? Can you grow all of it? How many resources does that take near where you live? How about in the mountains near where you live? Now go learn how to do it.
Because, like you said, we do need to step up our game. The middle of the road is not good enough. We must resist both the naivety of the techno-optimists as well as the doomist fatalism. Any perspective that leads to inaction is wrong.
The CO2 emissions from a world full of vegetarians vs a world full of vegans are pretty close to indistinguishable.
gotta say i see the challenges between animal-free and car-free life as much the same: most people around me generally agree we’d be better off with both these lifestyles, but the issue is practicality. best way to promote veganism around me in the past couple years has literally been to cook vegan meals with friends. if the stigma you’re talking about is “vegan food stinks” or “vegan food’s hard to prepare”, then that’s an easy way to address those two.
It may have higher emissions, but that's not the sole metric I use when deciding what to do. I think that would result in clinical depression, because I could always ratchet down my emissions by, for example, buying fewer board games, until I just don't really do anything.
Can't even go camping with a gas stove!
In everyday life I don't generally discuss my diet beyond small talk.
So you'd probably lump me in with that 95% of irrationals, because in person, I'd just try to change the subject.
The fact is though that board games and gas stoves are nothing in comparison to animal husbandry.
"Animal agriculture produces 65% of the world's nitrous oxide emissions which has a global warming impact 296 times greater than carbon dioxide.
Raising livestock for human consumption generates nearly 15% of total global greenhouse gas emissions, which is greater than all the transportation emissions combined. It also uses nearly 70% of agricultural land which leads to being the major contributor to deforestation, biodiversity loss, and water pollution.
Ending our meat and dairy production could pause the growth of greenhouse gas emissions for 30 years, new study suggests."

I'm happy to discuss it, but almost always, including now, it seems to be a waste of time, because I agree with you! I think you're correct in identifying that a vegan diet has lower emissions and externalities than an omnivorous diet.
The top thing is for people to consider emissions and allow emissions to become part of the decision process. In terms of diet that could be to introduce and consider food outside of the cultural limits, like shell fish and sea weed. A related issue are that a large number (majority?) of Europe and northern American lakes has major issues with eutrophication with mostly fish that people refuse to eat because of culture. Eating those kind of fish would solve two problems at the same time, feeding people and removing uncontrolled overgrowth caused by artificial fertilizers.
Right now it is also cheaper to operate heavy machinery that run on fossil fuels to control plant growth in nature reservation and around power lines, rather than raising animals that would do the same job and create food. Same thing with Lawn mowers. One of the most ecological method to keep grass cut is (real) free range hobby scale chickens. Produce food, cuts grass and keeps pests away.
As with everything else, everything change if people allow emissions to be part of the decision process.
A carbon tax would do so. Unfortunately it's hard to get anything done nationally, much less globally
In lieu of that, despite variance in environmental impact across foods, on the whole, the average vegan diet is almost certainly going to be far better for the environment than a non-vegan diet.
And this is not even getting into other positive elements such as health and animal welfare, but those are unrelated topics likely to spark additional argument, so I won't go further.
Emissions are not a significant consideration in this global economy. The key factor that everyone cares about is cost.
https://www.colorado.edu/ecenter/2022/03/15/it-may-be-uncomf...
Climate change is primary caused by humans burning fossil fuels, and humans extracting fossil fuels to be used in chemical processes like artificial fertilizers. In the short term it might be beneficial to reduce the number of animals that eat plants that has sequestrate carbon from the air, but in every case it would be worse if we humans use fossil fuel to burn the same plants.
Some people has argued that in the very short term, reducing methane while increasing emissions of fossil fuel emissions could beneficial be a better strategy if we can know for sure that carbon capture will save us in the future. I am doubtful to that strategy.
It should be noted that methane leaks from fossil fuel industry is larger than that from cows. A primary source of those methane leaks are the production of artificial fertilizers, but of course all steps between extracting natural gas to producing the fertilizers has large amount of emissions and leaks.
Solving that faster, is what is needed. Maybe instead of having everything be handled at the top level inter community personal outreach is needed.
What you eat is personal - having an impact on emissions/environment is not solved at a personal level, it requires nation level negotiations.
What you eat is at best a signal to higher level political groups of your inclinations.
Political groups are lazy and/or inept and will assume such.
As far as veganism is concerned, it is notable that it is much easier to be vegan now than 20 or even 10 years ago, as vegan ingredients are more widespread and higher quality, and "vegan options" are essentially standard in restaurants. This didn't happen through legislation, but by the application of social pressure by vegans - if vegans can't eat at your restaurant, they won't just go somewhere else, they'll take their friends with them. It is the output of a massive multiparty negotiation.
If you're talking about "convincing people to go vegan", most people don't like being preached to regardless of the topic, that's not a stigma.
For example, drinking alcohol has its' negatives, but if I'm in the pub with friends and some teetotaler decides to go off on a mission to convert me, my response is going to vary from smiling and nodding to telling them to piss off depending on the mood I'm in that day.
Like, uh, the comment you replied to.
Maybe there's a way to fix this with language? If someone says that they use the metro or cycle to work, I'm like, cool man, trains are sick, let's chat.
If someone says they "support a car-free lifestyle", I'm probably already starting to think about something else and glazing over.

Here are the rolled up stats, which indeed show animal agriculture using more than transportation:
https://www.colorado.edu/ecenter/2022/03/15/it-may-be-uncomf...
An incredibly strong feedback mechanism exists (see article above).
Societal problems, yes. Extinction to the human species? I think that’s extreme hyperbole. What would the mechanism even be, to eradicate all humans, across the globe?
Climate change is real, things will be bad, etc, but the possible end of the species is an incredible claim, that doesn’t follow logic.
What is "this kind of argument"? Something ridiculous was stated, and I pointed out an apparently annoying reality. The argument that you seem to want to have is unrelated to what was said and my response to it. I don't think hyperbole has a place on meaningful discussions. Relevant points should be made without theatrics.
Now we got these fungi chewing things all up. Thanks a lot, fungi.
Higher CO2 levels are said to have led to a "global greening", in which crop yields have gone up a lot. This is especially true in Africa, so that reduces global hunger and increases wealth. The idea that more CO2 = less life is not as simple as it's made out to be. Climate doomers ignores this type of thing because they are convinced society can't handle complexity, so have to insist that CO2 is always bad even when it's not.
https://fee.org/articles/rejoice-the-earth-is-becoming-green...
The argument is that the total effect of increasing CO2 in the atmosphere is net negative for most people.
Crop yields have gone up a lot? Unfortunatly our farming has even more problems, but let's leave it at the increased greening: How much have crop yields increased by that please, any numbers? Or at least how much the increase of greening is?
Do you know our crops vs the plants that mostly benefit from this and will also thrive in the future weather conditions, that is more than the CO2 level?
Hunger in Africa has already reduced? Please wtf, any numbers?
And that this will outweigh the other bad consequences.. no comment.
Even your reference doesn't get to anything more concrete than wishful but hilarious extrapolation based on ... just opinion (vs facts of.. but I think it is not worth continiueing, right? :/ )

If you really need to "make" something "sure" please pick something real and not a political football.
In the early 70's alarmists were "making sure" everyone was panicking about an ice age.
See..no ice...
Wait a while....I predict the alarmists will change to something else when people no longer buy the current looming disaster.
Please stop participating in the most recent fashionable doomsday fantasy.

https://www.nytimes.com/1976/07/18/archives/the-genesis-stra...
But there is considerable evidence that this warm period is passing and that temperatures on the whole will get colder. For example, in the last 100 years mid‐latitude air temperatures peaked at an all‐time warm point in the 1940's and‐have been cooling ever since.
[Climatologists] are predicting greater fluctuations, and a cooling trend for the northern hemisphere.
The most imminent and far reaching [danger] is the possibility of a food‐climate crisis that would burden the well to do countries with unprecedented hikes in food prices, but could mean famine and political instability for many parts of the non-industrialized world.”
So writes Stephen Schneider, a young climatologist at the National Center for Atmospheric Research in Boulder, Colo., reflecting the consensus of the climatological community in his new book, “The Genesis Strategy.”
Yes Wikipedia claims that "Having found that recalculation showed that global warming was the more likely outcome, he published a retraction of his earlier findings in 1974". Yet there he is in 1976 - two years after this supposed retraction - telling the NY Times that there's an absolute scientific consensus on global cooling.
Wikipedia isn't reliable for anything climate related or on many other topics. Their citation for this claim of a retraction doesn't go to any retraction, but rather a book written by a Guardian journalist.
It's really depressing how systematic this problem is. I'd try to fix Wikipedia with a link to the 1976 interview but there's no point, it'd get reverted quickly for sure.
For the wider point here see my other comment. According to present day understanding not only the media but also scientists were massively misleading the public about the climate and what other scientists believed. So how do you know it's not still happening?
Cool, we're going to be like that. What's depressing is that I made the effort when you tried to pull things off into a rabbit trail of to a single book review.
To be clear you didn't refute my initial argument here which looked at the state of the scientific community, you threw out a (from the sounds of things favorite cherry picked) book review from the New York Times.
> So how do you know it's not still happening?
Because it's much easier for scientists to have their own independent voices and easier to hear from the scientific community directly. Our ability to communicate these points, much like the science itself, is greatly improved from the 70s.
This point is relevant because you can't directly measure what the scientific community believes. It's not even a well defined group to begin with. So in practice everyone relies on summaries, articles, assertions by scientists about what other scientists believe and so on. If you read HN discussions on climate you'll see all kinds of things stated with 100% certainty that everyone believes those things, but it's easy to find research papers refuting them or providing contradictory evidence. Whilst communication abilities are indeed better than the 1970s this does not lead to more rational discussion because attempts to bring up the complexities and contradictions of the actual evidence base are invariably suppressed, along with people pointing out the unreliability of the climatological community. Many scientists today in climate will tell you point blank that their views are never brought to public attention and even actively suppressed.

The central thesis is that the climate crisis has already been solved with technology and capitalism. The worst offenders (like Max Roser of Our World in Data https://twitter.com/MaxCRoser) overemphasize success in western countries and hint the problem lies in China and India not doing enough.
A more run of the mill climate optimist claims that the efforts we’ve done so far are enough to avert disaster, and we just need to do more of the same. The YouTube channel Kurzgesagt (https://www.youtube.com/watch?v=LxgMdjyw8uw) is guilty if this form of denialism.
Err, just NO. This is largely due to global trade being flat for the past 10 years [1], this is a good proxy to measure real economic growth. Don't believe GDP as an indicator of real growth, they keep on adding fictitious sources to these numbers. Did you know that rent is part of GDP? And even rent that homeowners would have paid to a landlord had they owned their home? [2]
So basically this is just about the world becoming poorer since the 2008 financial crisis (and covid of course).
Also, "not following the worst case scenario" is not really a reason to rejoice, 4.5 degrees is still absolutely terrible.
Also, funny enough the page they link to as a source for "Global CO2 emissions (both fossil and land use) have been relatively flat" has for title "Analysis: Global CO2 emissions from fossil fuels hit record high in 2022" [3]. So, lols.
I could also add that less emissions growth doesn't mean less carbon accumulates in the atmosphere [4]

Of course renting is an economic activity that should be reflected in the GDP, and it is as "real" as anything else. To focus solely on international trade feels shortsighted as well. When a doctor sees you and charges you $200, that's going into the GDP but not into any trade balance.
The world is richer since 2008 by almost any metric you can think of, including inflation-adjusted per capita income which is independent of GDP.
If my neighbour owns a house (outright) and lives in it, I pay nothing, and no impact on GDP
If I rent from my neighbour for $10k a year, and he rents from me for $10k a year, GDP increases by $20k a year, but nothing has really changed, expect the amount of money paid in taxes.
So that's why you have imputed rent as part of GDP. Fine, I get that.
How about this scenario
I have a kid and look after it, I pay nothing, and no impact on GDP
My neighbour has a kid and looks after it, he pays nothing, and no impact on GDP
I look after my neighbours kid 3 days a week and he looks after mine, in an exchange, no impact on GDP
I look after my neighbours kid 3 days a week and he pays me $300, and he looks after mine 3 days a week and I pay him $300. GDP increases $600 a week, and more money is taken in taxes.
Do we include all unpaid work?
If I (a painter) pay my neighbor (a gardener) to garden my front yard and he pays me to paint his garage, then GDP increases.
If I do the gardening myself, and he does the painting himself, GDP doesn't increase.
How about me looking after my old parent vs me working overtime and paying a care home to do it?
> How about me looking after my old parent vs me working overtime and paying a care home to do it?
Yes of course the latter will have an impact on the GDP, and the former not. You are producing more work for money and you are buying more work for money.
If someone is paid to dig holes and fill them up right after, the country is not any wealthier even though GDP is increased, in fact slightly less wealthy because of wear and tear on the shovel/excavator.
A company that pays contractors to do nothing but dig up holes and fill them back up again will quickly go bankrupt, so most people aren't going to engage in such enterprise.
Just because you found a way to hack the GDP in an online argument doesn't immediately throw its usefulness in the real-world.
e.g. repairing a water main, then laying some underground electrical cables, then laying some fiber optic wire.
Due to inefficient coordination, country A may have the same patch of ground dug up and filled three times.
Whereas country B, more efficient, only has to dig once, do all the work, then fill it up once.
So country B records lower GDP but in fact ends up slightly wealthier.
Shadow economies also exist and comprise different % in different countries.
I think the confusion here is because it seems odd that taking care of your parents by yourself is not considered productive unless you exchange money for it. GDP is an imperfect measure, and by definition does not take into account such voluntary/unpaid activities.
The caregiver is doing the same work either way. Where is the wealth increase coming from?
The OECD definition seems suspect, an increase in money reserves does not guarantee an increase in wealth when there's been inflation. Do you have a source for it?
I neglected to mention I work in an old peoples home. The overtime is the exact amount of care my parent needs.
In a more realistic examples, alcoholics purchasing booze, obese people overeating, and people wasting their lives watching TV all contribute to GDP.
Not really because even if you are living in your own paid-off house, the rent will be added to the GDP.
> If I do the gardening myself, and he does the painting himself, GDP doesn't increase.
There is a law being worked out somewhere (probably Europe) that will tax any activity you are doing. If you paint your garage, this activity will be evaluated financially and you'll have to pay taxes on it. Not doing so is tax evasion.
* last one was /s but maybe not really?
New feudalism
But capital increase. Next time this capital will hit market - when you decide to sell fruits or home with beautiful garden it will be taxed and will increase GDP.
GDP is statistics anyway, so any work that doesn't rot and hit the market will eventually show up in GDP.
This is not true, at least in the US. If you're a homeowner, they estimate how much it would cost to rent your own home and include that in the GDP.
> So that's why you have imputed rent as part of GDP. Fine, I get that.
I then came up with other parts where economic activity is not imputed
It could be backed by products that nobody wants (wars and such) or it could be at the expense of other quality of life metrics such that the juice is not worth the squeeze.
It's like lifting weights to get huge instead of to get strong or healthy, you can end up some undesirable results.
How can a smart, presumably educated person not know that rent counts as economic activity?
To say the world is poorer than in 2008 is just utterly preposterous.
Per capita GPD in China went from 3500 to 12500. India 1000 to 2200.
There is half the world. US, Canada and Europe is only 15% of the population but I don't know how the case can be made we are poorer than in 2008 either.
https://www.propublica.org/article/yieldstar-rent-increase-r...
Of course it's "economic activity". But if I sublet to someone that sublets to someone that sublets to someone that lives in an apartment, that's a 4x increase in money flow but there's no production of goods or services at all.
It makes sense to have the cost of building and maintaining homes represented somewhere, but rent is a poor proxy for that.
Right, which is why the insult in the post I quoted is getting things very wrong.
> GDP only considers the value of the final consumed goods and services, and rent is a consumed service. If you're a homeowner, they estimate your rent and use that instead.
I understand that but it's a notably flawed way of going about it. Prices in general can have a loose coupling to value but with rent it's extra bad. A small change in housing stock can trigger a massive swing in rent and GDP even though the service being delivered doesn't change.
Watch this. Counting rent is about as sensible as counting financial services.
Gross World Product was about $43t in 2005 and $78t in 2014, so that would suggest international trade has increased from $10t to $18t in 10 years, nearly doubling, inflation adjusted.
You can say that the non-international part of GDP is overestimated, lets say by 40% more in 2014 than in 2005. That would mean that real GWP in 2014 was just 56t, and therefore the 18t international trade would actually be 32% -- a 33% increase in 10 years.
We're talking global control here so displacement is not that far fetched.
Also, related, check out Nate Hagens work on the Great simplification (he's got a podcast and on youtube). I won't spoil it here but he and his team of scientists have made some very interesting discoveries on future GDP growth.
People are consuming more international goods and more domestic goods, so trade as a percentage of trade relative to GDP has stagnated, but not volume of trade. Since 2008, maritime trade has increased by 3 billion tons or 37% [1].
> Did you know that rent is part of GDP?
It's also a component of the inflation, so it cancels out. Housing is getting more expensive, but part of it is that we are consuming more of it than we used to. Home sizes have been growing, but household sizes have been falling [2].
[1] https://www.statista.com/statistics/264117/tonnage-of-worldw...
[2] https://www.thezebra.com/resources/home/median-home-size-in-...
I suspect sheer maritime freight tonnage may be a less reliable proxy due to factors like cost of shipping changes, role of air freight, tariff changes, etc. Maybe share all the trade and globalization graphs instead? https://ourworldindata.org/trade-and-globalization
Your second source, hilariously, predates the entire pandemic (which is when home prices really took off). It also says very little to support your point that we're "consuming more" housing because home sizes are growing. The Case-Shiller U.S. National Home Price NSA Index seems to suggest that home prices were rising only modestly until the pandemic. https://www.spglobal.com/spdji/en/indices/indicators/sp-core...
This doesn't seem to match what you'd get by multiplying their figures of inflation-adjusted GDP [1] with their figures of exports as a percentage of GDP [2].
> Case-Shiller U.S. National Home Price NSA
Home prices aren't factored into in either GDP or inflation because they're considered an asset. You're right that the economy has stagnated since the pandemic, especially in America. My point is that it's absurd to suggest that the global economy hasn't grown in the past decade.

you raise concerns about the interpretation of GDP and use trade as a more believable replacement - but how about using manufacturing as a more direct replacement? it seems to have continued it's rising trend through the present. [2] rising by 50% in the last 10 years.

I think it is more fair to measure temperatures directly, as we already do, and make estimates from there. It's not the CO2 which would harm us (at least not that much), it's the temperature, so we need to base our analysis on the thing that interests us directly. And not on the derivative of the derivative of it (emission rates).
I suspect it doesn't matter how good are our models or how good are humanity's efforts in green tech. Until we are actually removing gasses from the atmosphere permanently, the planet is fucked. Just faster or slower, doesn't really matter.
https://keelingcurve.ucsd.edu/
You don't even need to be a big wig scientist to test this assumption. Open the graph on the big monitor and put a ruler or anything straight like a piece of paper to the median points corresponding to years 2000-2010. If emissions were "level" in the last decade then we should have 2010-2022 datapoints at most at the same line or even below the line. But in reality we see that the curve is raising up faster, meaning that the rate of emissions increased between years 10-22 compared to years 00-10, which contradicts author's graphs.
(To anyone a bit confused, the Keeling graph is the cumulative amount of CO2 in the atmosphere, so emissions are the first derivative of this graph.)
Not exactly. There is a net sink of emissions every year into the land & ocean, so d(CO2)/dt = emissions minus the net sinks, roughly. See the graph on CO2 partitioning [0]. A lot of research goes into whether these sinks continue at their current rate of removal.
[0] https://en.wikipedia.org/wiki/Atmospheric_carbon_cycle#Anthr...
1: https://substackcdn.com/image/fetch/f_auto,q_auto:good,fl_pr...
Easiest visually would be to integrate the emissions and compare it to the keeling curve, or differentiate the keeling curve and compare it to the emissions.
I think the secondary things you describe are almost large scale weather events, not quite climate.
But most fundamentally, the 'primary driver' of temperature change is CO2 and that's that so of course we have to measure it.
And yes, it's far more fuzzy than they let on, which is not good they should be more open about that, or find a way to communicate it more effectively.
No, the planet is not all 'fucked' and CO2 levels will go down as we put less in the air, and of course, if we want to start to decarbonize the atmosphere we can do that as well.
I wish they would use the term 'climate risk' - because risk all about less likely probabilities, than 'specific paths to the future'.
What? You are saying that if your are cooking meat on a skillet and turn the fire down from 3 to 1, or even to 0, then your meat temperature would start actively decreasing below the ambient temperature and freeze on it's own? Because that's what you are saying, literally.
I'm not against measuring emission rates, that's an important metric. I'm against making any far reaching assumptions based ONLY on the emission rates estimates. Because that's like cooking meat inside an opaque black box by measuring torque forces applied to the regulator over time. It loosely corresponds to the result, but the meat would be charred most likely, due to big amount of conversions and estimations. On the other hand measuring meat temperature with a thermometer inserted directly into it would give us a precision result.
Considering that nature provides carbon traps and that the Earth is ultimately in the void of the space, you cooking meat is a kitchen with opened windows and freezing weather outside, and you turn down the climate that was set to full throttle.
Permafrost won't help because first the planet need to cool down a lot and start general cooling trend. And we will be heating up the atmosphere due to existing gasses. So it's a dead end.
Vegetation is a linear carbon sink. Because microbes decompose dead vegetation and release gasses back in the atmosphere, the most of the captured carbon in vegetation must be in the actual alive plants. And number of alive plants scales linearly with the area we humans leave for them. Since humanity is increasing in numbers and each human demands more and more land to be used, I highly doubt that we can spare a lot of arable land for a NEW vegetation. So that's also dead end.
And at last oceans. I have no idea what is the capture mechanism of an ocean and how much carbon on it's own it can capture permanently. Maybe yes, maybe no. But considering that a) we are acidifying oceans, b) overfishing them, c) raise sea levels, d) heat up oceans - all this together would probably hamper natural carbon capture capabilities of an ocean.
So maybe this is possible. But I haven't heard a lot about such possibility from scientists, and I doubt it's a solution for our problem. Until some research will be done at least.
https://www.theguardian.com/environment/2012/jan/16/greenhou...
Overall the OP's assertion seems to be only technically ture - it seems that CO2 is indeed absorbed, but only on a scale of decades to centuries essentially.
You're having trouble with the meaning of word 'literally', but also analogies, and climate.
The earth has various mechanisms for absorbing CO2 over time.
If I have a cancer, and a lifestyle change would make the difference between whether the cancer kills me in four years or forty… I definitely wouldn’t say “I’m fucked anyway, no point in doing anything unless the cancer can be permanently removed.”
The problem is, this is not cancer, and all the people who take the "fucked anyway" view are damning the rest of us
Sure, it's great that we are changing our society globally, it is beneficial for us. If we will ever decide to cool the planet then green energy is must have tech for that, because we can't sequester gas while emitting more of it, it's dumb. But we are talking about a long term estimate now, and that one unfortunately in my uneducated opinion didn't change much. The heating rate didn't change much because of a few Leafs and Teslas on the road, and some northern EU countries actually reducing emissions.
1: Discover some previously unknown method to directly recreate cheap and easy unlimited photosynthesis either electrically or mechanically or
2: Somehow create a fan system that can atomically slice the carbon atoms off of gaseous co2 particles
And the one that we create is ALSO cheap enough to deploy world wide en masse capable of equal or greater CO2 concentration reduction than the number of CO2 producing ICE engines in use and industries put out, it's not going to ever be a miracle fix.
or
3: Hijack a currently existing biological system to do the heavy lifting for us:
I imagine that with government incentive something like a self-regulating robotic rooftop duckweed farms being required for every vehicle owning household, but something like that would first need to be perfected and made available at an affordable price, like $400 or less with minimal maintenance expense which is a HUGE ask considering that duckweed propagation is not a solved part of agricultural science.
I chose Duckweed because it is the fastest growing plant in the world, which can double in mass almost daily under ideal conditions, uses photosynthesis to convert water and carbon dioxide into oxygen and carbohydrates, fats, and proteins, and its dietary requirements are met easily, only needing a small amount of additives to common water and a ready source of carbon dioxide as could be handled by bubbling atmospheric air into the water.
Additionally, duckweed is edible by humans and animals, and if there were unconsumable excess as would be likely given 3 billion home duckweed farms, we could theoretically dry and burn it for carbon negative fuel (as the leftover carbon ash from the burn would count as sequestered carbon).
Alternatively, some genetically modified cyanobacteria could probably do the trick, but with risk of harm should it escape from its confines into the ecosphere.
http://en.wikipedia.org/wiki/Clathrate_gun_hypothesis
>While it may be important on the millennial timescales, it is no longer considered relevant for the near future climate change: the IPCC Sixth Assessment Report states "It is very unlikely that gas clathrates (mostly methane) in deeper terrestrial permafrost and subsea clathrates will lead to a detectable departure from the emissions trajectory during this century".
The planet will be fine. It will be different, but that's a normal thing in its 4 billion year history.
Whether it will be habitable for humans is a different question. I suspect we'll adapt (like we did for the last ice age), but I'm no expert.
On the bright side, more heat and CO2 means more arable land and better growing environment. Veggies and grazing animals are all I need to get by, food wise.
Just looking casually at topo maps and assuming the worst case I've seen (all land and sea ice melts, resulting in sea water rising 250'), the land we'll lose in coastal regions and major river basins is smaller than what we'll gain near the poles. Farming just Antarctica would probably produce enough food to feed the world several times over.
Edit: This isn't to say that worst case scenario wouldn't displace high percentages of the population or that that isn't a major issue; however, it's not an insurmountable obstacle given the gradual nature of the change.
I'd bet a paycheck that there's no top soil worthy of the name under all that ice. Same with when people yuk it up with, "we'll just farm Canada!" Have you seen the dirt in British Columbia? I don't think that soil could grow anything other than more dirt. (Though Manitoba and Saskatchewan would probably do better, dunno.)
I can understand how, over a period of years, farms near the equator may become less tenable and land farther from the equator more arable, but, at the scales I've seen (single digit average degrees up over the next 100 years), we should be able to account for that.
Edit: I don't know the Carlin bit you refer to. Link?
The standup I've referenced: https://www.youtube.com/watch?v=uHgJKrmbYfg I've seen way way too many folks on the right who take it at face value, literally. Even his not so subtle references that humanity will die out don't phase people with an agenda.
You don't know enough. Stop watching Carlin and go learn something about growing things in your environment.
If you live in the Northern Hemisphere step away from the keyboard, get outside, breath some fresh air and soak in the sunlight while you dig in the dirt and plant some food for yourself. Then perhaps you can think clearly enough to make steps that make sense.
So Earth will be fine and life will go on, the only thing that will destroy everything is when the Sun goes om nom nom many billions of years from now as it feasts upon its inner children to become a red giant.
Life itself survives, but most living things die. It would be pretty disingenuous to say "hey, an amoeba survived, who cares all other life is dead" - because somehow every second commenter seems to have the incredible insight "but the planet earth will not literally be destroyed, so why should we care".
Obviously we measure and study both and they both matter so the point is somewhat moot.
> Until we are actually removing gasses from the atmosphere permanently, the planet is fucked.
I happen to agree with this, but realize that's exactly the same metric: it's just negative GHG emissions. We would do the same thing: simulate potential future outcomes given an emission / capture balance that is overall negative, estimate what might happen, and then measure what we're actually doing to see whether we might actually be on that path or not. Once we start removing gasses, it's still useful to track overall emission balance.
> What does this flattening of emissions and divergence from the high-end scenario mean for the climate going forward? First, its important to emphasize that a flatting of emissions does not mean that global warming will stop or the problem will be solved. The amount of warming the world experiences is a function of our cumulative emissions, and the world will not stop warming until we get emissions all the way to net-zero. Even after we reach net-zero emissions, the world will not cool back down for many millennia to come in the absence of removing more CO2 from the atmosphere than we emit.
> This is the brutal math of climate change, and the reason why its so important to start reducing our emissions quickly. We are already well off track for what would be needed to limit warming to 1.5C without large overshoot (and the need for lots of negative emissions to bring temperatures back down). If we do not start reducing global emissions over the coming decade, plausible scenarios to limit warming to below 2C will move out of reach as well.
In other words, this is heartening progress, but not an excuse for apathy.
Let’s keep bending the curve!
This does not mean that going to zero will be possible with just more of the same.
US and Europe, maybe. What about China and India?
"China permitted more coal power plants last year [2022] than any time in the last seven years, according to a new report released this week. It's the equivalent of about two new coal power plants per week. The report by energy data organizations Global Energy Monitor and the Centre for Research on Energy and Clean Air finds the country quadrupled the amount of new coal power approvals in 2022 compared to 2021"[0]
[0] https://www.npr.org/2023/03/02/1160441919/china-is-building-...
So, at least morally, they seem to have every right to increase their emissions, and it is up to us, the largest historical polluters, to contract our economies if we are serious about both climate change and moral rights. Why should we expect to live in luxury in the EU while peasants in India live without electricity just because they can't afford a non-coal power plant?
Of course, an even better approach would be for the large historical polluters to contribute funds, manpower and know-how, freely, to build clean power and clean industry in China and other places.
And finally, I am also well aware that this is higy idealistic and none of this has any chance in hell of happening. We'll just keep pointing fingers at China and India (and the USA, speaking as an EU citizen) and avoid too much actual change.
Per capita is relevant when we are talking about countries or regions, if not the easy way is to cut the region in 2 and say you have cut emissions by 50%.
The per capita is irrelevant is often used by small countries as an excuse for not doing anything because "they" are so many more than "we", so what "we" do don't change anything
If they build 2 coal plants, we can tear down 4 natural gas plants and still reduce overall emissions. Sure, we may need some rolling blackouts, but such is the price - we'll still live much better than the vast majority of the world.
This will change with more wealth though. We must ensure that future energy hunger in India (and Africa) ist not satiated by fossil fuels.
But yeah, we need a lot more investment in non-fossil-fuel energy production, and we need to be able to move and store electric energy on a much bigger scale than we can now. Fossil fuels for ground transportation needs to stop being a thing. We can do it with existing technology, we've just chosen not to.
I'm also a little wary that the apparent plateau in the data might not pan out in the longer term. Particularly because of carbon cycle feedback loops that we may not be seeing the worst of yet.
> Ultimately, the progress we have made should encourage us that progress is possible, but the large and growing gap between where we are headed today and what is needed to limit warming to well-below 2C means that we need to double down and light a (carbon-free) fire under policymakers to ratchet up emissions reductions over the next decade. Flattening the curve of global emissions is only the first step in a long road to get it all the way down to zero.
The tone of which suggests the studies are not wide-ranging enough:
each study has its flaws and limitations, as do all scientific studies, and
in combination with the North American/European bias where most of studies
were conducted, this means that it would be a stretch too far to say the
science currently supports global insect declines: the jury is still out on
insectageddon.And more! Destruction of coastal mangroves. Groundwater over-extraction. Pollution of freshwater reservoirs and rivers. Destruction of tropical rainforests and their collections of many possibly useful organisms.
A while ago (2010?) the US Defence National Intelligence Council's report on threats labeled climate change a "force multiplier".
That's all it is, really: the least of the things we're doing wrong, that we will have to fix this century. It makes the real problems a bit worse.
People are going to be really disappointed when we change the car fleet to 100% EV, but somehow things still keep getting worse.
There MUST be more sustainable ways of farming than killing the biosphere.
The size of the increase each year is much higher now than in 1980s even accounting for the increased CO2 value. So the rate of change has increased.
The bigger and counterintuitive picture is that vast numbers of people do not enjoy the quality of life that is nominally achievable with todays technologies and a more peaceful and better managed world would actually enormously increase emissions unless we find sustainable substitutes for whatever really contributes to quality of life.
We need to snap out of such absurd incentives and false dilemmas. The task is global sustainable prosperity and we are lucky to have a worthy purpose.
It means that somehow, if we care about the environment, we may have to be against economic growth and/or good economic health.

It's not. Local emissions are a thing, too - a new car will have way cleaner exhaust than a 20 year old beater, and an electric vehicle even less. Nitrous oxide is the big issue in urban areas, the less of it is in the air the better for those having to live near high traffic streets.
Maybe because companies do not have interest in it? And this way there is nothing change: just produce the same, but with new type of engine. Even better, because more money is earned. Meanwhile ecology is about putting down the production, but the production blossoms for some reason...
Electric conversion kits exist, but these are relatively niche as you have to replace the entire guts of the car and have to find room for the batteries. It's way more cost-effective to buy a new, from-scratch electric vehicle.
> Why nobody produces filters for used cars?
Essentially every modern ICE car carries a whole portable miniaturized chemical factory with it - catalytic converters, particulate filters, systems to inject more fuel to burn off the particulate filter, adblue injection, constant real-time analysis of a whole host of different parameters... a retrofit to bring an older engine to modern emission standards is incredibly complex. You'd need to replace the entire ECU, place sensors everywhere, redesign the entire aerodynamics of the exhaust stacks so that the system doesn't collapse from accidental standing waves or pressure shockwaves, and have all of that certified to be road legal.
Oh, and on top of that you need to fight for every cubic inch of space as most vehicles of the last 20 years have been designed to be as compact as possible for aerodynamic reasons.
Again, not worth the effort.
Individual approval is a thing.
Improving local emissions is good but it doesn’t help with global emissions if you’re still buying a couple tons of metal which will sit idle 95% of the time and will on average haul 1.1 people when in use. There’s also a concern that EVs not only don’t help but actually worsen the health impacts of tire particulates.
They might take away my US passport for saying it but if we want to reduce emissions the solution isn’t spending more. The best options are things like walking, biking, taking transit, and eating less beef.
That's a different problem - US consumers are (lured to) buying SUVs because of an old loophole [1] and because SUVs make really good margins so manufacturers prioritize these in advertising. Nothing, absolutely nothing makes an electric vehicle be heavier than an ICE vehicle.
Comparing apples to apples, a Tesla Model S clocks in at 2255kg max dry weight, a 7-series BMW at 2525kg.
[1] https://www.wired.com/story/the-us-wants-to-close-the-suv-lo...
Indeed, but during the course of its operation, the BMW will consume a ton of fossil fuels (which may be produced at harm to the environment such as with fracking) while the Tesla can be driven completely emissions-free using renewable electricity. It's a trade between upfront and recurring emissions, and given just how long cars can last (many a first-generation Tesla from over a decade ago is still on its first battery pack), I seriously prefer the former as the total lifetime emissions are what matters.
"The strongest witness is the vast population of the earth to which we are a burden and she scarcely can provide for our needs; as our demands grow greater, our complaints against Nature's inadequacy are heard by all. The scourges of pestilence, famine, wars and earthquakes have come to be regarded as a blessing to overcrowded nations since they serve to prune away the luxuriant growth of the human race."
We have been beating this same drum for nearly 2000 years, at least. Nothing is new, we're tripping ourselves ad infinitum.
Here is how the earth 'greenhouse effect' really works: https://m.youtube.com/watch?v=oqu5DjzOBF8&pp=ygUlZ3JlZW5ob3V...
This is why Co2 do not have any effect until it reaches the high troposphere. That takes 20 years. The average climate we have right now is caused by emissions from 2003.
I'll repeat that in the comments of every climate article I read by the way, sorry for the repetition. M
Whether the CO2 is pulled from the air or from more concentrated industrial sources, the carbon sequestration industry would need to grow to the size of the fossil fuel industry (in terms of mass moved). But instead of extracting resources and selling them for financial gain, it will be a pure financial loss for an ecological gain. Under capitalism it's as impossible as water flowing uphill.
> the majority of the world needs to agree
Mmmhhh, not sure if betting on a world economic agreement to protect our climate and biodiversity is a good idea.
But I personally expect things to just get worse and worse in the next few decades. Capitalism will not slow down and climate change effects will increase, driving migration into rich countries, causing societal uproar and reduced quality of life for everybody.
Not true, under the current EU emissions trading scheme you can actually earn money by selling the certificates for the CO2 you remove. If you check the price of it you can see that well defined markets can actually get the power of capitalism to work in your favour, with the price jumping from $30 to $90 within last year.
Please don't do that. Thank you.

When you're done with that search, look up volcano explosions on land and under the sea, and compare them to the explosive power of a missle.

There is nothing about “military engines” or “military supply routes” or “military explosions” that leads anyone to believe their impact would be any worse than their civilian equivalents, and even if they were, you still have to prove that they are so much worse that even their limited activity compared to the normal economy must be given priority attention.
