lazide•3h ago
Not that you’re wrong, but I find it darkly amusing that rather than than cut back on all the crazy things we’re doing, it would make sense to instead bio engineer a bunch of plant life to deal instead.
griffzhowl•3h ago
> cut back on all the crazy things we’re doing

How would you get grant money for that?

lazide•3h ago
Certainly ain’t gonna stimulate the economy either!
squigz•3h ago
Wouldn't it be the same way one would get money for bioengineering the global ecosystem? At least we know how we'd go about one of these options.
griffzhowl•26m ago
I think cutting back on what we're doing already wouldn't draw a lot of grant support.

We can make a presentation showing "Look, if we just ate in-season locally-grown vegetables and wore clothes made from the fibres of our locally grown nettles and wool we could solve the climate crisis in maybe 100 years!"...

It doesn't seem to be economically compelling for people in the UK or US who are getting tomatoes in January, living in a house made from bricks mass-produced in the third world, and clothed in threads made in Bangladesh.

I hope things can change, but it will take people waking up to the fact that their comfort is bought at the expense of many people far away suffering through long ass work days, and even if they then recognize it why would they change their habits?

I want everyone to live in sloth gardens - just reach out, grab a leaf, and there's your food.

It's a dream but that's how we grow <3

lumost•3h ago
What is the proposed mechanism for implementing a cut back? A global population with 8 billion people and 1950s carbon emissions implies an average living standard somewhere in the realm of the 1900s. Are you volunteering to move back to the horse and buggy?

Bear in mind that the industrialized world of 1950 was only inhabited by a small portion of the global population at most a billion people.

The only path forward is technological innovation to reduce or remove carbon emissions.

bix6•3h ago
I volunteer yeah. I can get everywhere I need on my bike so horse and buggy would give me enough range and prevent all the over touristing.
dingnuts•2h ago
there are many problems with this attitude but even bicycles require industrial processes and trade to maintain. Mainly the tires but if anything breaks the metallurgy for the spokes wouldn't be available
JackMorgan•2h ago
This feels like whataboutism. "Sure, you're not doing international air travel and avoiding all the incredible waste of a modern car, but whatabout that small amount of resources needed for a bike?!"

It encourages helplessness and fatalism. Don't let perfect be the enemy of good.

bix6•1h ago
Sure there are also many problems with saying only tech can fix all our issues. Tech is the reason we have all these issues in the first place. People survived just fine in teepees. Some might even say they lived a better life before the tech (guns) and non-native disease enabled by tech (travel) wiped them out. Swap the bike for a horse then. All you need for that is wild food and people who care about animals.

I’d be completely happy with technological innovations that allowed us to restore heat balance (solar radiation management, marine cloud brightening, etc). That can buy time for transitioning from fossil fuels.

tcoff91•2h ago
The moment anyone tries anything on that scale of geoengineering, they will immediately be blamed for whatever weather-based natural disasters that follow. I just don’t see how this can work without creating massive diplomatic tensions.
oorza•1h ago
I mean, if I had Elon Musk money, I'd build some kind of giant carbon capture mechanism. Perhaps I'd buy the largest basalt quarry I could find and start sequestering carbon at a planetary scale. It would cost a ton of money, but I'd do it in secret. If it worked, eventually it would show up on the scales, and I'd emerge from the shadows. This particular method of carbon capture could potentially work at a planetary scale and could potentially be done in secret, at huge cost, but the only blocking factor today is money.

https://eos.org/articles/basalts-turn-carbon-into-stone-for-...

This is the answer to carbon storage by the way, people just do not know about it. There's more than enough reactive mineral sites on the planet. The process is basically just dissolving CO2 into water, heating it, and soaking basalt in it to allow crystals to form. The water becomes heavier than ground water and can simply be poured into the Earth. The unsolved problems are optimization problems: direct air capture of CO2, using saltwater, that sort of thing.

If the world's billionaire class decided to buy carbon sequestering, we could have global CO2 levels returned to 1900 levels within a decade or two. The technology exists, the economic willpower does not.

https://www.bbc.com/news/world-43789527

> Potentially, basalt could solve all the world's CO2 problems says Sandra: "The storage capacity is such that, in theory, basalts could permanently hold the entire bulk of CO2 emissions derived from burning all fossil fuel on Earth."

Having said all of that, this is likely the most dystopian option. It's the "tech bails us out, yet again" solution because we could deploy it thoroughly enough that we can solve climate change without addressing any of the existential issues that got us here. The right combination of corporate+government partnership commercializing this technology and making it mandatory is a very plausible way to arrive at "there's 4 corporations on Earth that run the show" a la Aliens.

lazide•1h ago
I think you don’t understand the true scale of the problem. Just the additional fossil carbon being put in the atmosphere by the US alone is trillions of KG/yr.

Not only is there no way to hide trying to do something about it at that scale, there is no single site (or even multiple sites) that could handle that amount of sequestration - we’re talking hundreds.

And even Elon Musk could not afford it, even if he dumped everything he had into it.

oorza•1h ago
No, but you could do enough of it in secret with Elon Musk resources to prove that it's both planetarily viable and doesn't cause catastrophes by existing and then lend your political weight to having it scaled up globally. By the time the public heard about it, it would already be a done deal.

I think you could prove it out at a scale that people could measure on planetary CO2 sensors for a couple dozen billion dollars, then take that data to a sitting POTUS you're friendly with and work out a multi-trillion dollar commercialization plan, using the USA's global bullying power to immediately establish a global monopoly.

A particularly cynical view would be this CEO buying global laws that dictate carbon neutrality while simultaneously also making it impossible to achieve without his CCS. Then merely canceling a sales contract topples a regime and you've arrived a global corporatocracy.

lazide•30m ago
Mind doing some math and showing your work?
tcoff91•1h ago
Carbon capture is probably the only geoengineering thing you could do that isn’t going to be massively controversial. Probably not practical though.

The other options mentioned like messing with the atmosphere to make it reflect more heat into space will likely cause wars due to lack of global consensus

marcosdumay•9m ago
It's very much the wrong time to scale carbon capture. Doing some pilot plants for research is a good idea, but if your goal is to see the effects on the global plots, you should be working on something else.

There's a sibling with the long-form reasoning. The problem is that we are pushing a lot of new carbon into the atmosphere, you just won't be able to scale anything enough and there's a really big opportunity cost to try to push the tide away.

How does that make sense? The US reduced their emissions by shifting production to China, and China gladly lapped it up (in massive amounts).

It would be good to have a graph showing where the ultimate products of these emissions ended up.

tfourb•27m ago
Ask and you shall receive: https://ourworldindata.org/consumption-based-co2

You will notice that the picture does not change radically if you include emissions from trade (which is what you were asking).

Turns out while China expects a lot of stuff to the us, it doesn’t have that big of an impact on net emissions.

griffzhowl•9m ago
Thanks, but what is it supposed to show? Looks like West outsourced their production to the East and this data just shows that?
Arainach•2h ago
We could start by banning things that explicitly waste resources such as proof of work cryptocurrency and adjust tax incentives to punish huge energy consumers for things like AI. Make the energy cost factor in the long-term externalities and maybe companies will hesitate before burning the world for things that aren't necessary.

Things don't have to be perfect - you start with the biggest polluters/consumers and use trade incentives to convince other nations to join. We've seen this work under Democratic administrations (China's outputs are dropping) before Trump etc. threw it all away.

exoverito•1h ago
Disturbingly authoritarian impulses for a dubious prescription.

The climate goes through natural cycles, we are actually coming out of a global temperature low after the ice age. Cold eras are actually far more dangerous throughout human history, for example the Little Ice Age during the Dark Ages which caused widespread crop failures and famine in Europe. Warm eras are correlated with the golden ages of civilizations, such as the Roman Warm Period. Zooming out over geological time, the Earth is currently near an all time low in terms of surface temperatures.

Cryptocurrency functions as a decentralized means of exchange outside of the control of centralized powers. Governments have been feverishly debasing their fiat currencies, which has fueled inflation, pricing many young people out of owning a home. It would seem you would rather trap people in an inflationary monetary paradigm, justifying it with secular eschatology. Millenarian Marxists have similarly latched onto climate change as their justification for abolishing private property, policies of degrowth, and other anti-human initiatives.

Energy per capita is tightly correlated with living standards. We saw broad wealth increases up until about 1970, after which energy per capita flat lined, and income inequality started worsening. Europe has implemented many of the polices you want, and has achieved nothing besides deindustrialization and irrelevancy.

China's CO2 emissions are increasing dramatically, and they continue to build more coal and natural gas plants. The USA and Europe reduced their emissions mostly by offshoring manufacturing to China.

It seems you're deeply confused about how the world works.

anon84873628•1h ago
>Warm eras are correlated with the golden ages of civilizations

Yeah, and hot eras kill civilizations. There's a famous one called the 4.2 kiloyear event. Does modern mesopotamia seem like a great place for the birthplace of agriculture?

I don't necessarily agree with the parent's politics, but you seem to be completely ignoring the categorical difference of CO2 emissions and associated risks of climate tipping points to our civilization.

oceanplexian•57m ago
> Does modern mesopotamia seem like a great place for the birthplace of agriculture?

Actually yes, if not for the massive cultural and political dysfunction.

Modern Day Mesopotamia would be one of the most agriculturally productive regions in the world if managed. Like the California Central Valley and Central Arizona which share similar climate classifications and are the most productive regions (per Acre) on the planet.

roelschroeven•1h ago
If you think the rise in global temperature that's going on now is going to lead to the golden ages of civilization, you're deeply confused about how the world works.

Go to the Wikipedia page on the Little Ice Age, have a look at the graph Global Average Temperature Change, and explain to us how current climate change is at all comparable to the Little Ice Age, or the Medieval Warm Period for that matter.

Or have a look at https://xkcd.com/1732/ (scroll all the way down) to get an idea of the rate and scale of temperature changes throughout human history.

ethanpailes•1h ago
China turning the corner on emissions has far more to do with their desire to get out from under the possibility of an oil blockade locking up their economy than green pressure from the west. They also organically have an environmental movement, though not one that they are willing to kowtow to at the cost of growth.
keyringlight•1h ago
Another factor for China was their cities choking on smog. One of the anecdotes I remember from Covid was that mask wearing in Asian cities was just another thing you did depending on that aspect of the weather, except in 2020 it had another reason behind it.
keyringlight•1h ago
I think a cap on what consumption you're allowed until you can prove utility to society would be beneficial. That said, with crypto it was distributed so it'd be extremely hard to enforce, and using the example of how AI has played out there's companies willing and able to dump money speculating on it just so they don't lose out if it does bear fruit. I expect for anything in future that shows potential they can organize themselves around regulations faster than new rules and enforcement could adapt.
lazide•1h ago
Notably, I’d count ‘technological innovation to reduce or remove carbon emissions’ as cutting back on the crazy.

I’m pretty sure that’s long forgotten now in the list of national priorities eh? Definitely in the USA. With war on their borders even the EU is reconsidering plans eh?

griffzhowl•1h ago
> The only path forward is technological innovation to reduce or remove carbon emissions.

Jared Diamond said a funny thing in his book 'Collapse', when talking about the last person on Easter Island to have cut down a tree.

Easter Island had at one point been densely forested and supported a dense human population. When Europeans found it there were no trees and it was sparsely populated. It's thought that their famous Moai statues were rolled to the shore on logs, and trees were found plentifully according to the pollen record there.

Anyway, Diamond envisages the person cutting down the last tree as thinking "It's ok, technology will save us!"

griffzhowl•47m ago
btw, Jared Diamond's "Collapse" begins with a chapter on Montana gold mines. When I first got it I thought "oh no, this is gonna be boring af", but his depth and breadth of knowledge made even that captivating. I also learned later in the book about the Greenland Norse and their ups and downs, and that was also revelatory. Reading that book was one of the top edifying experinces of my life. I highly recommend it.
tfourb•33m ago
CO2 emissions are not the driving force behind economic development. Energy is. And energy generation has been decoupled from CO2 emissions in almost every major economy, including China. Heck, in many countries economic growth has been decoupled even from energy use, with economies growing while energy use shrinks.

And while technological innovation is always nice, we always possess all the technology we need to get rid of the vast majority of emissions today. It’s just a question of implementation (ie the political will to spend some money and maybe reduce the share price of a few fossil fuel companies).

Amezarak•2h ago
That's a good practice anyway. Focusing on the capability to flexibly adapt our agriculture ensures long-term survivability. Focusing on hyper-efficient extraction that assumes a steady state gives a high-output but incredibly fragile agricultural industry. One black swan event, like a few volcanic eruptions, and we're all toast - and of course, the climate is constantly shifting even in the absence of such events and human inputs, just more slowly.
griffzhowl•3h ago
What's the connection? I thought the Ci would be Koppen climate classification but it's actually alternate carbon-fixing photosynthetic processes
colechristensen•3h ago
C4 is more efficient than C3 photosynthesis and allows plants both to produce more energy and to do so with less water which is an adaptation for hotter, drier climates.
i_k_k•2h ago
Plants build three-carbon sugars during photosynthesis by fixing a CO2 molecule onto a two-carbon chain with an enzyme called RuBisCO. In a typical "C3" plant, this happens relatively directly. But RuBisCO can screw up and fix an O2 molecule instead, and the erroneous result costs the plant energy to repair.

As the temperature rises, so does the error rate. At a high-enough temperature, the plant loses energy overall, which it can't survive long term.

C4 plants separate this process into two steps spatially. They build a four-carbon molecule in a much less error-prone way, then move this to a part of the cell where it's broken down into CO2. RuBisCO is again used to build the three-carbon sugars, but because the relative concentration of CO2 to O2 is so high, the error rate is low. There's some additional overhead to this process, but it pays off in warm climates.

Incidentally, there's another warm-climate metabolism: CAM (crassulacean acid metabolism). CAM works by temporally separating parts of the process. At night, they open their stomata, and use CO2 to build an acid. During the day, they close their stomata, cleave CO2 off of the acid to increase the concentration, and let RuBisCO its thing.

I believe RuBisCO is the most common enzyme on Earth by weight. I find it striking that Mother Nature has had to find all these hacks to get around its shortcomings, but hasn't found a way to simply fix the enzyme so it doesn't make so many errors.

Yeah, ok. I read about half the article and it was just talking about growing tomatoes in Texas rather than their homeland of the northern Andes.

Now I see in the last paragraph it says C4 photosynthesis is more efficient in hot climates and C3 more efficient in cooler climates.

I don't see though what's the benefit of bioengineering C3 plants to operate with C4, rather than to utilise C4 plants where the climate is suitable for them?

thfuran•1h ago

Some areas are already running short on arable land suitable for some C3 species. Check out the napa cabbage harvests from Japan and South Korea, for example. Japanese rice production is also struggling, though that’s a more complicated example with several causes.

He does have one paragraph about tomatoes, but he also talks about Andean cacti like Browningia candelaris, "plants from places like cloud forests of Central America", Solanum pennellii, and "plants from (...) the Páramo of Ecuador".

My mother was able to grow tomatoes successfully in Pohnpei, which is at 3° latitude and never gets outside the temperature range of about 23°–32°. https://weather.com/es-GT/tiempo/10dias/l/cc8849a0250ec854cb.... They were pretty leggy though; she had a hard time keeping them alive.

chimpanzee•46m ago
> He's talking about growing tomatoes all the way through the article. Nothing but talking about how tomatoes grow

This is flat-out wrong. (And the comment you replied to is also wrong.)

He mentions tomatoes only 6 times in about 1500 words. These words appear half-way into the article, in only 2 of the roughly 16 paragraphs. Three of those instances are in direct reference or comparison to the wild ancestors of tomatoes.

While not specifying, the article also mentions high-altitude, tropical plants and cacti.

jyounker•5m ago
I think you're overstating his point.

While you can grow them in, lets say, Houston, they're not easy to grow. They get infections at the drop of a hat, and if you so much as turn around, some sort of insect will munch through them. They don't yield much fruit, and the fruits they do yield generally leave something to be desired in the flavor department.

This is his point. The plants don't have much energy to fend off infections or predators, and they don't have much less energy to put into their fruit.

If you put a tomato plant in a more suitable climate, the things are nearly weeds. You put them in a bucket, make sure they get enough water, and you a few months later you have sweet, juicy, flavorful fruit with basically zero effort.

While we've bred cultivars that can be grown in places like Houston or Florida, the plants don't particularly like it.

Plant metabolism depends on temperature and light in a way they can't control. If it's too warm and/or sunny, plants "run too hot" and exhaust themselves to death. If it's too cold or shady, they can't "run enough" and die from inadequate fuel and other biochemical precursors.

You can, if you keep them cool with shade and water if it's not excessively humid.

I practice zone denial with a shade house and have things like rhubarb, cilantro and lettuce growing right now. It's been over 100F many days this summer and these would not make it outside. I also have many varieties of tomatoes and pretty sure I'm the only one the region who does because they would not set fruit outside in these temperatures.

If it's a dry climate and you have water and shade, you can turn it into a moderate or cool climate.

mythrwy•2h ago
It's kind of a fine line with tomatoes because they really really do not like cool nights nor cool soil.

But if it's too hot they will not set fruit. You get blooms but they just drop.

Some tomatoes are more adapted to cool and others to heat. I have found Roma and cherry tomatoes set in hotter temperatures (generally) than many others.

1) did you start them indoors or buy seedlings? Getting a late start could delay things.

2) did you water them enough?

3) did you have good holes for them? Tomatoes do well if they can root deeply - giving them a 2-3' deep hole filled with good soil and compost helps.

4) cages: indeterminate tomatoes can grow huge, So give them a cage with plenty of space - the crap little cages you get at Home Depot do not suffice. If they were determinant, this does not apply.

Tomatoes do well in full sun but need quite a bit of water if it's dry. And possibly some calcium - we compost our egg shells as one source.

Thanks for these insights!

I did get seedlings this season, and even planted them mid May. I thought I did pretty well not being late this year.

The only thing I can think of is not enough water; I had a thick layer (1-2 inch) of straw for mulch, and figured that would let me water less frequently. (Though I did do a finger check every few days).

Interesting you mention the cherries; it's the only plant with fruit even this late in the season. The others are assorted regular size varieties like Cherokee or other heirloomy types.

(edit: correction: it was mythrwy in the sibling comment that mentioned the cherry tomatoes! Thank you as well.)

Agreeing with you and mythrwy: in Pittsburgh, our cherry tomatoes have been gonzo the last few years and our heirlooms have been only middling productive.

Which is annoying because they're so much more work to cook with. :)

Well ok, if you modify the environment to have a different climate then you can grow things that grow in that modified climate...

I don't know why the post title doesn't include the "Why" prefix from the source. Which is really a botany explanation rather than simple horticultural complaint.

mythrwy•1h ago
Agreed. But I saw an opportunity to show off my awesome tomatoes! (which would not grow here without shade).

Can you tell us a bit more about your greenhouse/hoop house? I’m in the CO front range - so very dry, cool nights, but quite hot in the sun. Our patio is getting re-done and I’m thinking about how I might rebuild our planters to better support growing tomatoes.
mythrwy•40m ago
Sure. I intend to put it in a blog at some point.

I'm several hundred miles due south of you in SE New Mexico, also right along the rocky front range, so similar climate with intense sun and day/night temp swings, although we are much warmer obviously.

The frame of the shade house in the video is cattle panels and the cover is called "aluminet". The cattle panels are hooped and tied to a wooden frame with posts sunk in the ground. It started as a simple 10'x20' structure but I kept adding rooms and and other portions are not hoop type. Someone gave me a 10x10 frame that is very tall from an old "greenhouse" so I tacked that on. The doors are used screen doors also covered with aluminet. It's been an ongoing process over years. But it hasn't been expensive, I would say under $1000 for the entire structure including redoing the cover once. The cover is secured with a zillion zip ties and has nylon straps to keep it from flapping (we get extreme winds).

There is a lot more I could say on the subject but hopefully that gets you some things to look into.

bikelang•13m ago
This is excellent - thank you. We have extreme wind as well - so that was a piece I’ve been trying to keep in mind.

Joey has really pushed boundaries on botany. Great to see his thoughts being discussed here. I think everyone could learn something from him

I’m looking into building a shadehouse. I think I need that a lot more than my greenhouse, especially as the climate changes. Summers are just brutal and my garden plants getting some shade some of the day under trees are doing a lot better than ones in full sun.

but who wants to grow slime and mold anyway?!?

Apparently I have cool climate plants: apple, avocado, lavender those are germinated from seeds and blackberry, and fig from cuttings also living in a hot and humid climate. Definitely they can grow here, but can they be farmed? Of course not without expensive climate controls
7thaccount•1h ago
Blackberry and it's variants like dewberry are very common in the south and do fine in the high heat and humidity. It's almost impossible to kill. I have 4 different varieties growing wild and in planters at my house.

I also have many apple trees and they do struggle - even the native varieties. I think that's mainly due to fungus, aphids, and the poor soil though.

No idea about avocado.

a012•1h ago
Yep, blackberry grows like weed here but I’m fine with them because its fruits.

I sowed apple seeds from the supermarket apples (Covid time) so probably that’s why they adapted well. They definitely love the sun and heat.

griffzhowl•1h ago
Are you talking about the southern US? How can there be native apple varieties? I thought they were all originally from around central Asia and a quick look on wikipedia confirms this
marcosdumay•1h ago
Wait, avocado and lavender are supposed to be cool climate plants?

They grow like weeds around here. The tomatoes the article cites don't grow as well, but are still perfectly farmable.

Besides, people have been adapting species for other climates for millennia. I don't think it makes sense to talk about entire species that way.

And you can not grow hot-climate plants in heating up cool zones, as the swings winter to summer remain. We need to transport possible neophytes that wont survive in the bulbbelt up the temperature zones and help them via selective breeding to acclimate.

I assure you people who live in Phoenix grow things like Tomatoes and Lettuce perfectly fine in winter months. The OP would learn more visiting his local gardening center than vomiting up a bunch of wikipedia facts.
nothercastle•2h ago
Great blog I bookmarked it. It’s so hard to find articles written at this level.
sollewitt•1h ago
Good thing we're not doing anything silly like heating the entire planet. That would be a very alarming finding if we were.
HarHarVeryFunny•27m ago
On the upside, since Trump's tariffs are going to make importing tomatoes/etc from Mexico in winter unaffordable, maybe winter here will become warm enough that we can grow them here!

The Iowa corn crop may start failing, but we can start growing pineapples instead. Cows eat pineapples, right ?

Wouldn't a hydroponic setup help the author with this?

Dumb question, but is it difficult to setup a temperature and humidity controlled box or room where you could stow away the plants at night? A possibly dumber question, why do hydroponics always seem to involve indoor/UV lighting? Why are there no container-sized setups that you can place outdoors, but the climate and sun-light is controlled, and it's all powered by solar energy?

(sorry for all the dumb questions, i don't know anything about this topic)

NooneAtAll3•1h ago
do you mean greenhouse?

I guess in this case it would have to be greenhouse with good AC?

MathMonkeyMan•52m ago
You can do hydroponics outside, but it will still be warm at night. And with hydroponics, you need to prevent the water from getting too warm -- the roots will rot. So you might have trouble during the day, too.

[This guy][1] does a bunch of hydroponics and hydroponics adjacent projects outdoors.

All of these things are possible, but the cost difference between “put the plant in the dirt” and “put the plant in a specially constructed climate and humidity controlled box” are why large-scale hydroponics are only really used for high profit margin crops for which there’s a good reason not to just plant them outside.

In southern Sweden the vast spruce forests are starting to die because of the spruce bark beetle. You can see it everywhere now.

Supposedly due to warmer summers.

And new planatation replace spruce by larch or leaf trees.

Luckily they don't seem to affect pine trees, but they have their own climate expectations.
