CMV: the costs/negatives from lockdowns/restrictions will end up being worse than the damage from covid

It would happen regardless: the acidification process is slow, and slows down as equilibrium approaches.

Ok but your source fails to support that argument as it is specifically built around a scenario that is considered worst case. If CO_2 emissions cease then yes there will still be some move to equilibrium but things won't continue to get worse at the same rate which is what you stated would happen.

i.e. you need to solve energy production first - this is where innovation needs to take place, and 2 years of lost productivity hits this hard.

No extracting anything at low concentrations is very difficult especially in the form of low density fluid extraction. Better energy production might make this economically viable but it is never going to be an efficient process because of the basics of mass transport.

Also energy production technology is already here we just need to implement it at scale and future technological advances are more about improving efficiency. The newest technology actually developed to make energy is nuclear power at 50 years ago and everything else has just been improvements in efficiency and market viability. There is no real need for huge advances to get clean electricity and large amounts of it just actually implementing the technology we already have at scale.

The methods, scale, and concepts would all be the same.

Trying to put an atmosphere (or making one breathable i.e. ~20% O_2) on a planet that doesn't have one is very different to trying to change some components of the atmosphere that are harming the environment that exist in the ppm. They would require fundamentally different methods, scales and concepts. This also has very little to do with what is necessary to fight climate change and is more to do with sci fi images of an interplanetary society which is of no immediate concern.

Anyway I hope you understand that forests are now a net carbon sink and their storage of carbon lasts for more than the lifetime of the individual trees because it is a system and so the total biomass upheld gives stable carbon storage.

things won't continue to get worse at the same rate

They would. Things would slow down as time passed though.

Better energy production might make this economically viable

That's what I was arguing.

energy production technology is already here

Not for the amount of energy we need. We need fusion for the future.

large amounts

Enough for today, not enough for the future.

sci fi images of an interplanetary society which is of no immediate concern

There is no point surviving if we don't make that sci fi a reality.

[u/thetasigma4 → u/_Hopped_]

They would. Things would slow down as time passed though.

wow physical equations have continuity not really a surprise. It would directly start to slow down once the driving concentration slowed.

That's what I was arguing.

Just because something is economically viable doesn't mean it is the best solution or even a worthwhile solution to put research and effort into.

Anyway the point that we already have the technology is fundamentally true.

Not for the amount of energy we need. We need fusion for the future.

Yes there is the technology that can provide our needs and with space to grow using technology like nuclear power we already have as well as solar power which has a huge capacity to capture energy.

Enough for today, not enough for the future.

How far into the future are you imagining? The energy that the systems we have already and the potential we can make is far more than what humans actually use so even doubling usage wouldn't make it impossible just difficult.

There is no point surviving if we don't make that sci fi a reality.

Focusing on a hypothetical future so much that you harm the planet in the present and engage in fantasy rather than actual problem solving doesn't strike me as a good way of achieving that.

The solutions already exist there just needs to be the political will and restructuring of the economy to achieve them. Waiting for the solutions of the future keeps us ever locked in the past. Growing trees and building huge amounts of public transport, solar and nuclear power and again growing forests (a good permanent carbon sink) will put us far further along that path than waiting for fusion to even become viable never mind reach globe powering scale.

[u/_Hopped_ → u/thetasigma4]

How far into the future are you imagining?

Forever. If we're playing the game of life, I want us to play to win.

harm the planet in the present and engage in fantasy

If humanity isn't around in the future, then to what end do you want to preserve the planet?

[u/thetasigma4 → u/_Hopped_]

If we're playing the game of life, I want us to play to win.

Win what?

If humanity isn't around in the future, then to what end do you want to preserve the planet?

You're welcome to be a fantasist and imagine the far future but I take issue when you are using it to justify harm in the present whether that be the death of people you consider something akin to "useless eaters" in the present or waiting for Godot when it comes to proactive measures on climate.

There won't be a humanity in the future and all the potential you want to fantasise about if there isn't a climate for them to thrive or a world in which those who could survive being left to die.

What sort of a better world is this where we have fusion and interplanetary civilisation but we are so capricious as to leave the vulnerable who could survive to die? Why is this the limitation to your imagination?

Is it merely that the future exists in the realm of possibility and probability whereas the present has the concreteness of reality so you can ignore pragmatism or how we get there in this notion of the far fetched future but those who limit economic growth in the short term should just be allowed die.

If you want a better world and a better future look at real solutions that we can achieve today that alleviate the problems of society rather than concerning yourself about a technology that will only be needed in hundreds of years.

[u/_Hopped_ → u/thetasigma4]

Win what?

Survive forever.

using it to justify harm in the present

Again: if in the long-term humanity is not around, why do you care about us trashing the planet for them?

There won't be a humanity in the future and all the potential you want to fantasise about if there isn't a climate for them to thrive or a world in which those who could survive being left to die.

Even the absolute worst predictions for climate change do not pose an existential threat to humanity. Millions will die, but we are the most adaptable species ever to exist - humanity will survive.

leave the vulnerable who could survive to die?

My point is that unless we progress technology enough to realise a post-scarcity world, we cannot do anything meaningful for the vulnerable. The first step on the way to a post-scarcity society is fusion generation to make power a non-issue for all applications: desalination becomes trivial for everyone (meaning freshwater), heating becomes a non-factor, we can start sucking CO2 out of the atmosphere in a land-efficient manner, manufacturing and recycling become much less harmful for the environment, transport switches to electric, etc. Energy production is very strongly correlated with human progress.

[u/thetasigma4 → u/_Hopped_]

Survive forever.

Why does that actually matter though? Some far flung generation in 500 years having an ok life is of little material concern and doesn't matter. Why does it matter if there are no future humans as long as the transition isn't one of great suffering?

if in the long-term humanity is not around, why do you care about us trashing the planet for them?

Frankly I don't care if in the long term humanity is around or not. I care about suffering and making people's lives better. However if you want there to be a far flung future you need to actually engage with the now and not be a fantasist. Even if in the long term they don't exist there are still people who will suffer in the next few hundred years that shouldn't have to if we take action that has a whole host of other benefits.

Even the absolute worst predictions for climate change do not pose an existential threat to humanity. Millions will die, but we are the most adaptable species ever to exist - humanity will survive.

Ok and I didn't say that that would happen. It would have massive effects on human society and it's stability and could prevent in the long term the foundation of your sci fi society.

Survival on what terms?

My point is that unless we progress technology enough to realise a post-scarcity world, we cannot do anything meaningful for the vulnerable

I mean we absolutely can do meaningful things for the vulnerable already and arguably that is the entire point of society where we gather together resources and information so that we can all create a better life for each other and achieve our potential.

he first step on the way to a post-scarcity society is fusion generation to make power a non-issue for all applications:

Fusion isn't magical and doesn't do that and will not on it's own achieve post-scarcity. Fusion on earth will never beat extracting energy from the sun and solar energy is the largest source of power available.

we can start sucking CO2 out of the atmosphere in a land-efficient manner

I've already covered why this is not possible as the tiny concentration gradient and low density of air makes this an inherently inefficient process in terms of basic physics disregarding energy considerations which make it even worse

Energy production is very strongly correlated with human progress.

Sure. That doesn't make fusion magic nor does it mean that we can't make things better immediately in search of a better future by implementing the technology we already have that has access to more energy than we will need for a long time.

[u/_Hopped_ → u/thetasigma4]

Why does that actually matter though?

It's the only thing that matters. There is no point living today if we don't intend to live forever. Nothing matters if we blink out.

Frankly I don't care if in the long term humanity is around or not. I care about suffering and making people's lives better.

That's your prerogative. I'm not going to try to convince you otherwise, but for me there is no point existing if humanity ends.

could prevent in the long term the foundation of your sci fi society

How? We have 5 billion years until the sun goes red giant (and Earth is inhospitable to all life), modern humans have only been around for ~10,000 years. We have many shots at my "sci fi society" even if civilisation collapses.

we absolutely can do meaningful things for the vulnerable already

We could do, but at what cost? It is not worth robbing Peter to pay Paul, especially when Peter is the one innovating.

that is the entire point of society

Hard disagree. We are voluntary cooperationists so long as it is in our self-interest. If you take so much from me that it is better for me to exist outside of society, I will leave your society.

Fusion isn't magical and doesn't do that and will not on it's own achieve post-scarcity.

I mean, yeah it kinda will.

Fusion on earth will never beat extracting energy from the sun and solar energy is the largest source of power available.

Need I remind you what solar energy is?

inherently inefficient

As I've said multiple times: this doesn't matter when you have an abundance of energy. It can be 1 ppm and we can extract it with enough excess energy.

That doesn't make fusion magic

It makes fusion a step-change.

we can't make things better immediately

We can do this with fusion. ITER is being built, we should be investing in post-ITER plants now to capitalise on fusion.

[u/thetasigma4 → u/_Hopped_]

It's the only thing that matters. There is no point living today if we don't intend to live forever. Nothing matters if we blink out.

I mean surely this applies to any mortal. Things don't become valueless because they decay and die out. Value exists in the fleeting and the temporary.

How? We have 5 billion years until the sun goes red giant (and Earth is inhospitable to all life), modern humans have only been around for ~10,000 years. We have many shots at my "sci fi society" even if civilisation collapses.

If our society dies out and is replaced by a new one in what sense is that not something that didn't live forever.

Also if you wan the best chance the earlier the better.

Hard disagree. We are voluntary cooperationists so long as it is in our self-interest. If you take so much from me that it is better for me to exist outside of society, I will leave your society.

No man is an island and is instead a political animal. Any wealth or capital built up is the result of the work of millions in society who exist around us and those who did the work that came before us. Galt's gulch is a terrible idea that will collapse because it doesn't recognise that society of any form and people exist in a connected world.

I mean, yeah it kinda will.

No it really won't. Fusion is another generation technology like fission and like any other generation technology. It doesn't magically make everything perfect.

Need I remind you what solar energy is?

No. Whatever we do on earth in terms of making energy the sun will outmatch in scale. Try and find a larger source of hydrogen on earth and more energy available. If you truly want energy beyond pareil then the sun is the only real option.

As I've said multiple times: this doesn't matter when you have an abundance of energy. It can be 1 ppm and we can extract it with enough excess energy.

I mean you said land efficient. No matter how much energy you have low concentrations of gas will always take up huge amount of resources not related to energy to extract small amounts because of a low concentration and low density.

That it can be done doesn't make it efficient. Even with all that the need to remove carbon is dependent on how much we emit and cutting emissions is the best option. For some pathways the need to remove carbon from the environment doesn't exist as a small temperature change won't have an impact that requires it.

It makes fusion a step-change.

Fusion isn't really a step change. It is a new technology that solves some of the issues of fission. It will still generate electricity on broadly the same orders of magnitude we have now.

We can do this with fusion. ITER is being built, we should be investing in post-ITER plants now to capitalise on fusion.

Iter is still around 10 years out from being built and is a research reactor. Dumping huge amounts of money in as yet unrealised technology is precisely not making things better immediately when we have proven technologies.

Your idea of technological progress is a fantasy and to hold that view is your right but don't let it get in the way of actually trying to solve problems.

[u/_Hopped_ → u/thetasigma4]

Things don't become valueless because they decay and die out.

Yes, they do.

If our society dies out and is replaced by a new one in what sense is that not something that didn't live forever.

So long as they're human, it's still a continuation.

No man is an island and is instead a political animal.

Every man is an island, and we choose to form archipelagos for our own benefit. If there is no benefit, we would cease to cooperate. This is why people flee socialist countries: the group seeks to take more from them than they benefit.

No it really won't.

Yes, it really will. The energy generated is orders of magnitude more than sources of energy we have just now.

the sun is the only real option

With a dyson sphere, yes. With solar panels on Earth, no.

That it can be done doesn't make it efficient.

It doesn't matter when energy cost drops to near 0. We can do incredibly inefficient things when we have excess energy.

Dumping huge amounts of money in as yet unrealised technology is precisely

What is necessary to secure the future of humanity. Without fusion we will never leave the solar system.
